Product Safety 3-1 3. Product Safety This section consolidates the general safety warnings associated with the IntelliVue MX40. These warnings are repeated throughout the book in context where relevant. Safety symbols and other markings on the MX40 are also described here. General Safety ............................................................................................ 3-2 Safety Symbols & Other Marks ............................................................... 3-5
General Safety 3-2 Product Safety General Safety Warnings The MX40 operates exclusively via a wireless network connection, therefore, it should not be used for primary monitoring in applications where momentary loss of the ECG is unacceptable at the Information Center. It sends ECG and optionally pulse oximetry data to the Information Center, where the Information Center displays real-time patient data, provides alarm annunciation, data storage and review applications. The ECG waveform data, alarms and optionally SpO2 can always be viewed on the MX40 regardless of the connection to the Information Center. A wireless patient monitoring system will never be as reliable as a patient monitoring system that transmits its signal through a wire, due to the inherent nature of radio frequency and the many variables that affect over-the-air communication. This factor should be considered when electing to monitor patients using wireless technologies. If occasional loss of ECG monitoring at the Information Center is not clinically acceptable for certain patients, alternatives must be sought. As the IntelliVue MX40 does not provide a wired network connection, we would recommend the use of an IntelliVue patient monitor with a wired connection to the Information Center for these patients.  For continued safe use of this equipment, it is necessary that the listed instructions are followed. Instructions in this manual in no way supersede established medical procedures.  Do not touch the patient, or table, or instruments, during defibrillation. The battery door must be closed during defibrillation. These steps protect the clinician from high defibrillator voltage.  This device is not to be used in the vicinity of electrosurgical units because such use may interrupt or interfere with the transmission of signals from the MX40.  This equipment is not suitable for use in the presence of a flammable anesthetic mixture with air, or with oxygen or nitrous oxide.  This equipment is not suitable for use in an MRI environment.  Do not use patient cables with detachable lead wires that have exposed male pins. Electrocution could result if these pins are plugged into AC power.  Do not use patient cables or accessory cables and sensors if prior visual inspection reveals cable damage or the presence of liquid, lint or dust inside.
General Safety Product Safety 3-3  The system is not completely immune from radio interference although it is designed to minimize interference. Sources of interference that may be a problem include failing fluorescent lights and construction equipment. See "Electromagnetic Compatibility p. 15-8". The product should not be used next to or stacked with other equipment. If you must stack the product, you must check that normal operation is possible in the necessary configuration before the product is used on patients.  Do not rely exclusively on the audible alarm system for patient monitoring. Adjustment of alarm volume to a low level during patient monitoring may result in patient danger. Remember that the most reliable method of patient monitoring combines close personal surveillance with correct operation of monitoring equipment.  If the MX40 enters a continuous "boot-up" cycle or the main display does not appear or update, ensure that you are using a freshly charged lithium-ion battery or new disposable batteries. If the batteries are fresh and the device reboots or does not update, remove the device from service and contact your service personnel.  Place the MX40 in a pouch or over clothing, or both, during patient use. The device should not touch the patient’s skin during use.  Patients should be instructed not to open the battery compartment while the MX40 is in use.  Failure on the part of the responsible individual hospital or institution employing the use of this equipment to implement satisfactory maintenance as needed may cause undue equipment failure and possible health hazards.  Because the coverage range of Access Points can sometimes overlap, including different floor levels, the IntelliVue Device Location feature is not intended for use when attempting to locate a patient.  Short-range radio connections are subject to interruption due to interference from other radio sources in the vicinity, including microwaves, bluetooth devices, and DECT phones. Outside the frequency band and 5% above and below, i.e. the exclusion band according to IEC 60601-1-2, the short-range radio connection is immune up to 3V/m in the frequency range from 80MHz to 2.5 GHz. Depending on the strength and duration of the interference, the interruption may occur for an extended period. Any interruption of the signal due to interference, moving out of range, or for other reasons is indicated with a Tele Disconnected INOP message on the IntelliVue Patient Monitor.
General Safety 3-4 Product Safety Caution Philips recommends that when using a pouch to attach the MX40 to your patient that you consider your patient's condition and are careful about placement of the straps as the straps could present a strangulation hazard.

Operating and Navigating 4-8 Basic Operation Operating and Navigating The principle method of operating your MX40 is via the Touch Display. Almost every element on the display is interactive. Display elements include measurement numerics, information fields, alarm fields, waveforms, SmartKeys and menus. Power-On Self Test Once battery power is supplied, the MX40 performs a power-on self test to check operational status prior to start-up. Should a failure be detected, an INOP tone will sound and if possible, the appropriate INOP message for the failure will be communicated to the Information Center and displayed locally. A successful power-on self test will then transition the MX40 to the start-up screen. Selectable background colors can be configured and display on the screen for assistance with device identification. This can be helpful when devices are in a pooled use setting. If the MX40 enters a continuous "boot-up" cycle or the main display does not appear or update, ensure that you are using a freshly charged lithium-ion battery or new disposable batteries. If the batteries are fresh and the device reboots or does not update, remove the device from service and contact your service personnel. You must visually check that a waveform is present on the display. You can access further status information is by touching the status area on the display. Navigating Touching the Navigation Bar on the right of the display will scroll through additional display items. Solid downward arrows indicate there are additional elements that are not currently displayed. The arrows briefly illuminate when touched. Your selection from the menu also illuminates when touched.

Battery Information 4-14 Basic Operation Battery Information Battery Safety Information Warnings  The battery compartment door must be closed during defibrillation.  Use the Philips Rechargeable Lithium-ion Battery or 3 Duracell Alkaline batteries, size AA, MN 1500, 1.5V, to ensure specified performance and correct battery gauge reporting. Outdated, mismatched, or poor-quality batteries can give unacceptable performance (e.g., insufficient Battery-Low warning time). If you are using disposable batteries, the use of fresh high-quality alkaline batteries is strongly recommended.  Certain failure conditions, such as short circuits, can cause a battery to overheat during use. High temperatures can cause burns to the patient and/or user. If the MX40 becomes hot to the touch, remove it from the patient and place it aside until it cools. Then remove the batteries and discard them. Have the MX40 checked by your service provider to identify the cause of overheating.  If you receive a TELE BATTERY LOW, TELE BATTERY EMPTY, REPLACE BATTERY T, or TELE BATTERY TEMP alarm, the batteries must be promptly replaced. If these conditions are not corrected, they will result in a device shutdown and cessation of monitoring.  Disposable batteries should be removed from the MX40 at the end of the battery’s useful life to prevent leakage. If battery leakage should occur, use caution in removing the battery. The leaked substance may cause eye or skin irritation. Avoid contact with skin. Clean the battery compartment according to the instructions in the Maintenance section. Wash hands.  To eliminate the risk of electrical shock or burn, do not carry loose batteries on your person, e.g. in clothing pockets. Cautions  Use of AA Lithium batteries or batteries with terminal voltage >1.6V may cause damage to the device.  When monitoring with the WLAN version of the MX40 (Model 865352), the lithium-ion rechargeable battery is the only approved power source. Use of AA disposable batteries is not supported.
Battery Information Basic Operation 4-15 Lithium-ion Rechargeable Battery Care Care of the rechargeable battery begins when you receive a new battery for use and continues throughout the life of the battery. The table below lists battery care activities and when they should be performed. Activity When to Perform Perform a visual inspection. Before inserting a battery in the MX40. Charge the battery. Upon receipt, after use, or if a low battery state is indicated. To optimize performance, a fully (or almost fully) discharged battery should be charged as soon as possible. Clean the battery At each patient discharge, or in cases when the battery is exposed to contaminants. Charge stored batteries to at least 90% of their capacity every six months. When not in use for an extended period of time. Decommission the battery When any of the following INOPs are displayed on the MX40: TELE SERVICE BATTERY TELE BATTERY TEMP Rechargeable batteries are charged using the IntelliVue CL Charging Station. For information on charging station use, see Charging Li-ion Rechargeable Batteries p. 14-8 . Note — The battery capacity of re-chargeable batteries degrades over time and number of recharge cycles. Toward the end of its useful life, the battery capacity may be reduced by 25-30%. If this reduced battery life is unacceptable based on your use model, Philips recommends replacing the rechargeable battery sooner. Lithium-ion Rechargeable Battery Handling Precautions Lithium-ion batteries store a large amount of energy in a small package. Use caution when handling the batteries; misuse or abuse could cause bodily injury and/or equipment damage.  Do not short circuit - take care that the terminals do not contact metal (e.g. coins) or other conductive materials during transport and storage.  Do not crush, drop or puncture - mechanical abuse can lead to internal damage and internal short circuits that may not be visible externally.  Do not apply reverse polarity.
Battery Information 4-16 Basic Operation  Do not incinerate batteries or expose them to temperatures above 60oC (140oF). If a battery has been dropped or banged against a hard surface, whether damage is visible externally or not:  discontinue use.  dispose of the battery in accordance with the disposal instructions. Lithium-ion Rechargeable Battery Storage When storing rechargeable batteries, make sure that the battery terminals do not come into contact with metallic objects or other conductive materials. If batteries are stored for an extended period of time, they should be stored in a cool, dry place, ideally at 15oC (60oF), with a state of charge of 20% to 90%. Storing batteries in a cool place slows the aging process. The batteries should not be stored at a temperature outside the range of -20oC (-4oF) to 50oC (122oF). Stored batteries should be should be charged to at least 90% of their capacity every 6 months. They should be charged to full capacity prior to use. Note — Storing batteries at temperatures above 38oC (100oF) for extended periods of time could significantly reduce the batteries' life expectancy. Inserting/Removing Batteries Warning Arrhythmia relearning is initiated whenever the MX40's batteries are removed for one minute or longer. Be sure to check your patient’s arrhythmia annotation for accuracy whenever relearn has occurred. Caution Remove the batteries before storing the MX40 for an extended period of time.
Battery Information Basic Operation 4-17 The battery compartment is located on the back of the MX40, accessible by opening the compartment door from the bottom. It accommodates three AA 1.5V Alkaline batteries or the Philips Rechargeable Lithium-ion battery. Only these batteries should be used. Note— Lithium-ion batteries should be fully charged prior to first use. Important— Do not use other rechargeable batteries. Use of this type of battery will adversely affect:  Battery gauge performance  Battery low warnings  Battery life performance Inserting Batteries  Insert the rechargeable lithium-ion battery using the following procedure: Open the battery compartment by lifting up on both bottom sides of the compartment door.
Battery Information 4-18 Basic Operation 1 Remove the AA battery tray if present. 2 Insert the battery pack so that the raised tab is aligned with the cutout in the base of the battery compartment. 3 Close the battery compartment door. 4 Watch for the start-up screen on the front of the MX40 to illuminate briefly.
Battery Information Basic Operation 4-19  Insert AA batteries into the MX40 using the following procedure: 1 Open the battery compartment by lifting up on both bottom sides of the compartment door. 2 Insert the AA battery tray if not already present. 3 Insert three AA 1.5V Alkaline batteries, matching the polarity with the + indications inside the compartment. Note—all batteries are inserted with the + polarity in the same direction. Use of AA batteries is not supported with the WLAN MX40 (Model Number 865352). Use only the rechargeable lithium-ion battery. 4 Close the battery compartment door. 5 Watch for the start-up screen on the front of the MX40 to illuminate briefly. Removing the Batteries Batteries should be removed when the MX40 is not in use or is being stored. To remove the batteries, open the battery compartment door and push from the opening at the bottom of the compartment to pop the batteries out. Device settings (patient cable type, SpO2 mode, volume, etc.) are retained when the batteries are removed. Do not use AA batteries that have different energy levels remaining. Fresh AA batteries are recommended for each new application.
Battery Information 4-20 Basic Operation Important— Do not "store" disposable AA batteries by leaving them in the incorrect polarity position in the MX40. Be careful not to short circuit the batteries. Batteries can get hot when shorted. Short circuits are caused when a piece of metal touches both the positive and negative terminals simultaneously. More than a momentary short circuit will generally reduce the battery life. In case of a short circuit, discard the batteries, or just the shorted one if the batteries are new. Disposal of Batteries When disposing of batteries, follow local laws for proper disposal. Dispose of batteries in approved containers. If local regulations require you to recycle batteries, recycle batteries in accordance with those regulations. Battery Charge Status The battery charge indicator displays in the Status Area and communicates the remaining battery charge time when using both AA batteries or the rechargeable lithium-ion battery. When the MX40 is initially powered-on, it takes approximately 25 seconds for the indicator to populate. During this time, the indicator displays a ? in the battery icon. In order to guarantee overall device performance, certain functionality is disabled when the battery charge reaches critical levels. See the tables below for additional information about battery status.

If the Multi-Function button has been configured to generate a Nurse Call alarm, recording at the Information Center, or both, instruct the patient to use the button when needed. If desired, you can turn off patient use of the Multi-Function button at the Information Center. For more information see Patient Configurable Settings in Telemetry Setup p. 11-10.
Alarms 5-1 5. Alarms The section provides alarm information that applies to all measurements. Measurement-specific alarm information is discussed in the sections on individual measurements. Alarms Overview ...................................................................................... 5-2 Physiologic Alarms ................................................................................. 5-10 Technical Alarms (INOPs) ..................................................................... 5-14
Alarms Overview 5-2 Alarms Alarms Overview The MX40 has two different types of alarms: physiological alarms and INOPs. For MX40 devices operating with IntelliVue Information Center Release L and M, physiological alarms are not available locally on the MX40. INOPs are displayed as described here. For MX40 devices operating with IntelliVue Information Center Release N or IntelliVue Information Center iX, physiological alarms are available locally on the MX40 regardless of network connection to the Information Center. Alarm settings are as configured by the Information Center. Changes to physiological alarm settings can only be made at the Information Center. Audible alarm indicators are annunciated only when operating in Monitor Mode or when the MX40 is not networked connected. Physiological Alarms Physiological alarms are red and yellow alarms. A red alarm indicates a high priority patient alarm such as a potentially life threatening situation (for example, asystole). A yellow alarm indicates a lower priority patient alarm (for example, a low SpO2 alarm limit violation). Additionally there are short yellow alarms, most of which are specific to arrhythmia-related patient conditions (for example, ventricular bigeminy). INOPs INOPs are technical alarms, they indicate that the monitor cannot measure or detect alarm conditions reliably. If an INOP interrupts monitoring and alarm detection (for example, LEADS OFF), the monitor places a question mark in place of the measurement numeric and an audible indicator tone will be sounded. INOPs without this audible indicator indicate that there may be a problem with the reliability of the data, but that monitoring is not interrupted. Most INOPs are light blue, however there are a small number of INOPs which are always yellow or red to indicate a severity corresponding to red and yellow alarms. The following INOPs can also be configured as red or yellow INOPs to provide a severity indication:  ECG LEADS OFF  REPLACE BATTERY (when using disposable batteries)  TELE BATT EMPTY (when using the rechargeable battery pack) All monitors in a unit should have the same severity configured for these INOPs.
Alarms Overview Alarms 5-3 The MX40 is designed to achieve visual alarm notification at a distance of up to one meter, which is consistent with its intended use model as a wearable monitor. Alarms are indicated after the alarm delay time. This is made up of the system delay time plus the trigger delay time for the individual measurement. For more information see ECG Performance Disclosure/Specifications p. 15-27 . A downward facing arrow symbol next to the alarm message informs you that more than one message is active and the messages rotate every three seconds. The monitor sounds an audible indicator for the highest priority alarm. Visual Alarm Indicators Warning The MX40 display is inactive for a majority of the time because it is operating in Telemetry Mode. You must activate the screen to view or hear any alarms at the MX40. Upon activating the screen, the alarm volume may be set to zero if desired. Alarm Message An alarm message text appears in the alarm status area at the top of the screen indicating the source of the alarm. The background color of the alarm message matches the alarm priority: red for red alarms, yellow for yellow alarms, light blue for standard INOPs, red for red INOPs and yellow for yellow INOPs. The asterisk symbols (*) beside the alarm message match the alarm priority: *** for red alarms, ** for yellow alarms, * for short yellow alarms. Standard INOPs do not have a symbol, red and yellow INOPs have exclamation marks beside the alarm message: !!! for red INOPs and !! for yellow INOPs. If more than one alarm is present, there is a downward facing arrow symbol at the right side and the active alarm/inop messages rotate every three seconds. Alarm limit violation messages are displayed in text form, for example ** SpO2 LOW.
Alarms Overview 5-4 Alarms Alarm Indicator An Alarm Indicator on the MX40 main display communicates alarm/INOP conditions that have not been acknowledged. The alarm indicator is divided into two sections and appears in the upper right hand corner normally occupied by the time display. The right section flashes for a physiological alarm, except for short yellow alarms where the indicator will light for approximately six seconds. The color is yellow or red corresponding to the highest priority alarm currently present. An unacknowledged physiological alarm and INOP appears as (portrait view): An acknowledged physiological alarm and INOP with an additional unacknowledged physiological alarm appears as (landscape view): The left section lights continuously for a standard INOP and flashes for INOPs configured as red or yellow alarms as follows: INOP Color On Off Yellow 1.0 seconds 1.0 seconds Red 0.25 seconds 0.25 seconds If only physiological alarms are present, and no INOPs, the physiological alarms will use both left and right sections to flash (for red and yellow alarms) or light for approximately six seconds (for short yellow alarms). If only INOPs are present, and no physiological alarms, red and yellow INOPs will use both left and right sections to flash, but standard INOPs will always light continuously in the left section only. Once all alarm/INOP conditions are acknowledged, the time display reappears. Flashing Numeric The numeric of the measurement in alarm flashes.
Alarms Overview Alarms 5-5 Audible Alarm Indicators when in Monitoring Mode The audible alarm indicators configured for your monitor depend on which alarm standard applies in your hospital. Audible alarm indicator patterns are repeated until you acknowledge the alarm by switching it off or pausing it, or until the alarm condition ceases (if audible alarm indication is set to non-latching). Warning  Do not rely exclusively on the audible alarm system for patient monitoring. Adjustment of alarm volume to a low level or off during patient monitoring may result in patient danger. Remember that the most reliable method of patient monitoring combines close personal surveillance with correct operation of monitoring equipment.  No audible alarm indicators are available when the MX40's volume setting is zero or when operating in Telemetry Mode. Audible alarm indicators become active as soon as the MX40 is no longer connected to the Information Center. Traditional Audible Alarms (HP/Agilent/Philips/Carenet)  Red alarms and red INOPs: A high pitched sound is repeated once a second.  Two-star yellow alarms and yellow INOPs: A lower pitched sound is repeated every two seconds.  One-star yellow alarms (short yellow alarms): The audible indicator is the same as for yellow alarms, but of shorter duration.  Standard INOPs: an INOP tone is repeated every two seconds. ISO/IEC Standard Audible Alarms  Red alarms and red INOPs: A high pitched tone is repeated five times, followed by a pause.  Two-star yellow alarms and yellow INOPs: A lower pitched tone is repeated three times, followed by a pause.  One-star yellow alarms (short yellow alarms): The audible indicator is the same as for yellow alarms, but of shorter duration.  Standard INOPs: a lower pitched tone is repeated twice, followed by a pause.
Alarms Overview 5-6 Alarms Acknowledging Alarms To acknowledge all active physiological alarms and INOPs, touch the Silence Alarm button. This switches off the audible alarm indicators, if present, and alarm messages at the MX40 and at the IntelliVue Information Center iX. A check mark beside the alarm message indicates that the alarm has been acknowledged . If the condition that triggered the alarm is still present after the alarm has been acknowledged, the alarm message stays on the screen with a check mark symbol beside it, except for NBP alarms and alarms from other intermittent measurements. When such an alarm is acknowledged the alarm message disappears. If the alarm condition is no longer present, all alarm indicators stop and the alarm is reset. Switching off the alarms for the measurement in alarm, or switching off the measurement itself, also stops alarm indication. Pausing or Switching Off Alarms If you want to temporarily prevent alarms from sounding, for example while you are moving a patient, you can pause alarms, if configured. Depending on your MX40 configuration, alarms are paused for one, two or three minutes. Cautions  When operating with Information Center Release L or M, the alarm pause time of the MX40 is not configurable. The alarm pause time for the MX40 is always two minutes.  When operating with Information Center Release L or M, if alarms are paused at the Information Center, the "Alarms Paused" message is only displayed at the Information Center. To Pause All Alarms Select the Alarms SmartKey and select Pause Alarms. A timer on the display shows the remaining pause time.
Alarms Overview Alarms 5-7 While Alarms are Paused  In the alarm field, the MX40 displays the message ALARMS PAUSED 1:28 or ALARMS OFF, together with the alarms paused symbol or the alarms off symbol.  No alarms are sounded and no alarm messages are shown.  INOP messages are shown but no INOP tones are sounded. The only exceptions are the INOPs CUFF NOT DEFLATED, NBP CUFF OVERPRESS and INOPs relating to empty, missing and malfunctioning batteries. These INOPs switch the alarms on, and the INOP tones are sounded, even if alarms are paused or off. You need to remove the INOP condition first before you can switch the alarm tones off again. Warning If connection to the Information Center is lost during an alarms paused period, upon reconnection, alarms remain paused at the Information Center for the set time. You can resume alarms from the Patient Window at the Information Center at any time. Restarting Paused Alarms To manually switch on alarm indication again after a pause, select Pause Alarms. Alarm Limits The alarm limits you set determine the conditions that trigger yellow and red limit alarms. For some measurements (for example, SpO2), where setting the high alarm limit to the maximum of 100 switches the high alarm off, or setting the low alarm limit to the minimum of 0 switches it off. In these cases, the alarms off symbol is not displayed. Warning Be aware that the monitors in your care area may each have different alarm settings, to suit different patients. Always check that the alarm settings are appropriate for your patient before you start monitoring.
Alarms Overview 5-8 Alarms Viewing Individual Alarm Limits You can see the alarm limits set for each measurement next to the measurement numeric on the main screen. Reviewing Alarms You can see which alarms and INOPs are currently active in the respective alarms and INOPs fields at the top of the screen. To see the currently active alarms and INOPs listed in one place, touch the Alarms area. All alarms and INOPs are erased from the Alarm Messages window when you discharge a patient, or if you change to Demonstration Mode. Review Alarms Window The Review Alarms window contains a list of the 50 most recent alarms and INOPs with date and time information. The Review Alarms window also shows when alarms are paused or silenced. Note — Alarms that occur during an alarm suspend period will appear in the Review Alarm window, however, they are not communicated to the Information Center. Alarm Reminders The MX40 provides alarm reminders when operating with IIC Release N or IIC iX. The reminder time period is selected at the Information Center. For Information Center Release L/M, reminders are only available for INOPs.
Alarms Overview Alarms 5-9 Latching Alarms The alarm latching setting for your MX40 defines how the alarm indicators behave when you do not acknowledge them. When alarms are set to non-latching, their indicators end when the alarm condition ends. Switching alarm latching on means that visual and/or audible alarm indications are still displayed or announced by the monitor after the alarm condition ends. The indication lasts until you acknowledge the alarm by touching the Alarm Silence button. Alarm Latching Behavior Red & Yellow Measurement Alarms Non-latching Alarms Visual and Audible Latching Alarm has not been acknowledged. Alarm condition still present. Alarm tone on. Alarm message.

Alarm Behavior at Power On If the MX40 is powered off for longer than one minute and then powered on again (or after a loss of power lasting longer than one minute, or when a patient is discharged), the device restores the latest alarm settings from the Information Center. If battery power is lost for less than one minute, the alarm on/off condition prior to the power loss is restored.
Physiologic Alarms 5-10 Alarms Physiologic Alarms Physiologic alarms indicate a life-threatening situation or a less urgent situation such as heart rate beyond limits. Warning  Do not rely exclusively on the audible alarm system for patient monitoring. Adjustment of alarm volume to a low level during patient monitoring may result in patient danger. Remember that the most reliable method of patient monitoring combines close personal surveillance with correct operation of monitoring equipment. Arrhythmia alarm chaining and customizing arrhythmia alarm settings are described in the ECG and Arrhythmia Monitoring chapter. There are two levels of arrhythmia analysis available: Basic and Enhanced. Enhanced analysis includes Basic alarms. The MX40 provides physiological alarms based on the settings at the Information Center Release N or IntelliVue Information Center iX. Alarming is not active on the MX40 until it is configured via an active association with the Information Center. In the following table, Red (***) alarms are listed alphabetically, followed by the Yellow (**) alarms, and the Yellow (*) alarms. Note — The physiological alarm messages displayed on the MX40 use a short text format. Alarm messages displayed at the Information Center use and extended text format, e.g. "*HR yyy<xxx".

ECG Safety Information 6-2 ECG and Arrhythmia Monitoring ECG Safety Information Warnings  The MX40 operates exclusively via a wireless network connection, therefore, it should not be used for primary monitoring in applications where momentary loss of the ECG is unacceptable at the Information Center. It sends ECG and optionally pulse oximetry data to the Information Center, where the Information Center displays real-time patient data, provides alarm annunciation, data storage and review applications. The ECG waveform data, alarms and optionally SpO2 can always be viewed on the MX40 regardless of the connection to the Information Center.  Always confirm MX40 and Information Center observations with clinical observation of the patient before administering interventions.  To avoid patient injury, assure that the patient cable is not positioned where leads could become entangled around the patient, or cause choking, strangulation, or inhibit circulation in extremities.  Every lead must be secured to an electrode on the patient. Conductive parts of electrodes must not contact earth or other conductive parts.  EASI derived 12-lead ECGs and their measurements are approximations to conventional 12-lead ECGs. As the 12-lead ECG derived with EASI is not exactly identical to the 12-lead conventional ECG obtained from an electrocardiograph, it should not be used for diagnostic interpretations.  EASI lead placement is supported for adult patients only.  Ensure that the patient cable is properly connected to the MX40.  Do not mix and match electrodes of different types. In particular, do not use electrodes of dissimilar metals. This helps ensure optimal signal quality.  Non-manufacturer supplied accessories and supplies can corrupt the performance of the equipment. Use only AAMI EC-12 compliant electrodes with this device. Use of electrodes that are non-compliant may provide erroneous results.  During complete heart block or pacemaker failure (to pace or capture), tall P-waves (greater than 1/5 of the average R-wave height) can be erroneously counted by the arrhythmia algorithm, resulting in missed detection of cardiac arrest.
ECG Safety Information ECG and Arrhythmia Monitoring 6-3 Caution  To protect the MX40 from damage during defibrillation, to ensure accurate ECG information, and to provide protection against signal noise and other interference, use only ECG electrodes and cables specified by Philips.  Philips recommends that you change the lead label only to reflect the physical placement of electrodes. This will ensure a match between the monitored lead and the label, and prevent any possible confusion. Note— When switching from EASI to standard monitoring, there is a momentary loss of data. For Paced Patients Warnings  The output power of the MX40 and other sources of radio frequency energy, when used in the proximity of a pacemaker, can be sufficient to interfere with pacemaker performance. Due to the shielding effects of the body, internal pacemakers are somewhat less vulnerable than external pacemakers. However, caution should be exercised when monitoring any paced patient. In order to minimize the possibility of interference, position electrodes, electrode wires, and the MX40 as far away from the pacemaker as possible. Consult the pacemaker manufacturer for information on the RF susceptibility of their products and the use of their products with the MX40. See the IntelliVue Information Center Instructions for Use for additional information on monitoring paced patients.  When an external pacemaker is being used on a patient, arrhythmia monitoring is severely compromised due to the high energy level in the pacer pulse. This may result in the arrhythmia algorithm's failure to detect pacemaker non-capture or asystole.  Pacemakers that create fusion beats (pace pulse on top of the QRS complex) cannot be detected by the monitor's QRS detector.
ECG Safety Information 6-4 ECG and Arrhythmia Monitoring  For paced patients who exhibit only intrinsic rhythm, the monitor can erroneously count pace pulses as QRS complexes when the algorithm first encounters them, resulting in missed detection of cardiac arrest. The risk of missing cardiac arrest can be reduced by monitoring these patients with the low heart rate limit at or slightly above the basic/demand pacemaker rate. A low heart rate alarm notifies you when the patient begins pacing. Proper detection and classification of the paced rhythm can then be determined. Note— During defibrillation, monitoring may be temporarily interrupted or distorted. It may take several seconds for the ECG trace to reappear on the screen. After defibrillation, the device will continue to monitor as before; the device settings will not be affected.
Measuring ECG ECG and Arrhythmia Monitoring 6-5 Measuring ECG The electrocardiogram (ECG) measures the electrical activity of the heart and displays it on the MX40 and the Information Center as a waveform and a numeric. In order to compare measured ECG signals, the electrodes (or patient cables) are placed in standardized positions, forming "leads". To obtain ECG signals optimized for use in diagnosis and patient management in different care environments, different leadsets in varying lead placements are used. Standard lead, Hexad and EASI lead placements can be used with the MX40. The Heart Rate calculation resides in the arrhythmia algorithm on the MX40. Arrhythmia analysis is always turned on for telemetry patients. Arrhythmia analysis is either Basic or Enhanced, depending on the product configuration.
Connecting and Positioning ECG Electrodes 6-6 ECG and Arrhythmia Monitoring Connecting and Positioning ECG Electrodes Correct lead placement is always important for accurate diagnosis. Especially in the precordial leads, which are close the heart, QRS morphology can be greatly altered if an electrode is moved away from its correct location. Each electrode is color-coded. Use the placement diagrams available on the display of the MX40 and in this section for guidance. Additional lead placement information is available in the Online Help at the IntelliVue Information Center. When placing electrodes on the patient, choose a flat, non-muscular site where the signal will not be impacted by either movement or bones. Philips recommends that electrodes be changed every 24 hours. Clinicians will tend to see more motion related artifact on the ECG of ambulatory patients than on patients that are restricted to a bed. Proper skin preparation and electrode application are very important in reducing this problem. Problems with the ECG signal stem from two main sources: 1 Patient-related sources with noise on the waveform caused by clinical considerations such as poor skin prep, dry electrodes, and poor electrode adhesion, as well as by patient motion and muscle artifact 2 Frequency-related sources resulting in dropouts from signal disturbances and loss of signal. See Risk Management Considerations p. 15-5. Even in complex situations where problems overlap, most of the time you’ll be able to greatly enhance performance by taking corrective action. In addition to correct positioning of the electrodes, optimal skin preparation prior to electrode placement will help ensure a clear signal for diagnosis. 1 Prepare the patient’s skin. Good electrode-to-skin contact is important for a good ECG signal, as the skin is a poor conductor of electricity.  Select sites with intact skin, without impairment of any kind.  Clip or shave hair from the site as necessary.  Wash site with soap and water, leaving no soap residue. Note— Philips does not recommend using ether or pure alcohol, because they dry the skin and increase the resistance.  Dry thoroughly.  Use ECG skin preparation paper (abrasive) to remove dead skin cells and to improve the conductivity of the electrode site.
Connecting and Positioning ECG Electrodes ECG and Arrhythmia Monitoring 6-7 2 Check electrodes for moist gel, and attach to the clips. If you are not using pre-gelled electrodes, apply electrode gel to the electrodes before placement. Note— Gel must be moist to provide a good signal. 3 Place the electrodes on the patient according to the lead placement you have chosen (see the electrode placement diagrams following). Place the edge down, then "roll down" the rest of the pad. Press firmly around the adhesive edge toward the center. 4 Attach the patient cable to the MX40. An ECG waveform and numeric appear on the monitor display.
Selecting the Primary and Secondary ECG Leads 6-8 ECG and Arrhythmia Monitoring Selecting the Primary and Secondary ECG Leads When multilead analysis is used, the MX40 uses the primary and secondary lead selected at the Information Center to compute HR and to analyze and detect cardiac arrhythmias. They are also available for recordings and for display on the Information Center. Only the primary lead is used if your device is configured for single lead arrhythmia analysis. You should choose a lead as primary or secondary lead at the Information Center that has the following characteristics:  the QRS complex should be either completely above or below the baseline and it should not be biphasic  the QRS complex should be tall and narrow  the P-waves and T-waves should be less than 0.2 mV
Checking Paced Status ECG and Arrhythmia Monitoring 6-9 Checking Paced Status It is important to set the paced status correctly when you start monitoring ECG. Note — Paced status is set at the Information Center and can only be changed at the Information Center. When Paced is set to On:  Pacer Algorithm is switched on. This means that pacemaker pulses are not counted as extra QRS complexes.  The pacer spikes are shown in white.  The paced symbol is displayed. When Paced is set to Unconfirmed (IIC iX only):  Pacer Algorithm is switched on. This means that pacemaker pulses are not counted as extra QRS complexes.  The pacer spikes are shown in white.  The paced symbol with ? is displayed. When Paced is set to Off and your patient has a pacemaker, pace pulses may be counted as regular QRS complexes, which could prevent an asystole event from being detected. Warning  Pace pulse rejection must be switched on for paced patients by setting Paced to On. Switching pace pulse rejection off for paced patients may result in pace pulses being counted as regular QRS complexes, which could prevent an asystole event from being detected. At admission/discharge, always check that paced status is correct for the patient.  Some pace pulses can be difficult to reject. When this happens, the pulses are counted as a QRS complex, and could result in an incorrect HR and failure to detect cardiac arrest or some arrhythmias. Make sure that pace pulses are detected correctly by checking the pace pulse markers on the display. Keep pacemaker patients under close observation.

Lead label of the displayed wave 2. 1 mV calibration bar 3. Pacer spikes 4. Current heart rate 5. Current heart rate alarm limits 6. EASI lead placement label (located here when active) 7. Paced status ECG HR numeric: This is the heart rate derived from the monitored ECG. Pacer Spikes: The pacer spikes are shown in white.
Monitoring Paced Patients ECG and Arrhythmia Monitoring 6-11 Monitoring Paced Patients An ECG optimized for monitoring a paced patient should look like this: 1. Normal Beats 2. Pace Pulses/Beats Choose a lead as primary or secondary lead that has these characteristics:  the normal QRS complex should be either completely above or below the baseline and it should not be biphasic. For paced patients, the QRS complexes should be at least twice the height of pace pulses.  the QRS complex should be tall and narrow  the P-waves and the T-waves should be less than 0.2 mV. Optimizing Lead Selection for Paced Patients Some unipolar pacemakers display pace pulses with repolarization tails. These tails may be counted as QRSs in the event of cardiac arrest or other arrhythmias. If you note a visible repolarization tail, choose a lead that decreases the size of the repolarization tail. 1. Repolarization tail (note width) Avoid fusion and pseudofusion beats. 1. Fusion 2. Paced 3. Pseudofusion
Changing the Size of the ECG Wave 6-12 ECG and Arrhythmia Monitoring Changing the Size of the ECG Wave If any of the displayed ECG waves is too small or clipped, you can change the size of the ECG waves on the screen. Changing the adjustment factor only changes the visual appearance of the ECG wave on the MX40. It does not affect the ECG signal analyzed by the algorithm. Comparing the wave size to the 1 mV calibration bar on the ECG wave segment can help you get an idea of the true ECG signal strength.  To change the size of the ECG waves on the screen by a fixed adjustment factor: 1 Touch the HR parameter. 2 In the Setup ECG menu, scroll to the second page and select Adjust Size. 3 Select the required adjustment factor from the list.  Size X1/2 to halve the wave size  Size X1 to display the wave without zoom  Size X2 to double the wave size  Size X4 to multiply the wave size by four or 4 Touch the ECG wave and enter the size from the Change Wave menu. 5 Select the required adjustment factor from the list.
Choosing EASI or Standard Lead Placement ECG and Arrhythmia Monitoring 6-13 Choosing EASI or Standard Lead Placement Choose either standard lead placement or EASI lead placement: 1 In the Setup ECG menu, select Lead Placement to toggle between Standard or EASI. 2 Select Standard or EASI. Note — When changing lead placement, the patient cable must be attached to the MX40. EASI is shown beside the 1 mV calibration bar on the ECG wave on the display, and EASI is marked on any recorder strips and printouts. See the sections on Lead Placement for electrode placement diagrams.
Derived 12-lead ECG 6-14 ECG and Arrhythmia Monitoring Derived 12-lead ECG Hexad When operating with the IntelliVue Information Center iX, the optional Hexad ECG system generates a Mason-Likar 12-lead ECG from a 6-wire leadset (including four limb electrodes and two chest electrodes) placed according to the Mason-Likar 6-electrode placement. To generate a derived 12-lead ECG using this configuration, 8 out of the 12 leads are directly acquired (I, II, III, aVR, aVL, aVF and the two directly-recorded V leads) and only 4 precordial leads need to be derived. This means that 8 of 12 are identical to the 12 leads acquired using a full set of 10-wire standard ECG lead set. For more information refer to the 12 Lead ECG Monitoring Using a Reduced Lead Set Application Note, Part Number 452296278591. Caution Hexad derived chest leads and their measurements are approximations to the standard ECG, and should not be used for diagnostic interpretation. EASI The EASI system, a method of deriving 12ECG leads using a five-electrode configuration (4 monitoring electrodes and a ground electrode), has been developed to better address the goals and challenges of continuous ECG monitoring. EASI monitoring makes it possible to obtain 12-lead ECG information under continuous monitoring conditions across the continuum of care. The EASI method of obtaining a 12-lead ECG requires only five electrodes. The electrodes are placed on the upper sternum (S), the lower sternum (E) at the level of the fifth intercostal space, and on the right and left midaxillary lines (I and A) at the same level as the lower sternum electrode. A fifth ground electrode can be placed anywhere.
ECG Configuration ECG and Arrhythmia Monitoring 6-15 ECG Configuration The MX40 supports 3-, 5-, and 6-wire patient cables. The 5-wire patient cable can be used for either standard or EASI electrode configurations. The 6-wire patient cable can be used for either standard or Hexad electrode configurations. The MX40 detects the patient cable type attached and automatically determines the ECG measurement and transmitted leads. Note—The labels and colors of the ECG electrodes differ according to the standards that apply for your hospital. The electrode placement references and illustrations in this chapter use the AAMI labels and colors. See the table below for additional label and color information. Electrode Labels Electrode Colors AAMI EASI IEC AAMI IEC RA I R White Red LA S L Black Yellow LL A F Red Green RL N N Green Black V/Va E C/Ca Brown White Vb Cb Brown/White White/Blue Arrhythmia analysis resides in the arrhythmia algorithm on the MX40. Arrhythmia analysis is always turned on for telemetry patients unless operating with the IntelliVue Information Center iX, where it can be turned off. Arrhythmia analysis is either Basic or Enhanced (optional).
ECG Leads Monitored 6-16 ECG and Arrhythmia Monitoring ECG Leads Monitored Depending on the patient cable connected to the MX40, a different set of viewable leads are available at the MX40 and the Information Center. The MX40 can source up to four raw ECG waves to the Information Center. If you are using ... these leads can be selected at the MX40 and the Information Center 3-wire I, II, III Sourced (raw) waves are received as: Channel 1 = I, II, or III Factory Default is II. 5-wire (Standard mode) I, II, III, aVR, aVL, aVF, MCL and V Sourced (raw) waves are received as: Channel 1 = II Channel 2 = III Channel 3 = MCL Factory Defaults are II, V, III. 5-wire (EASI mode) I, II, III, aVR, aVL, aVF, V1, V2, V3, V4, V5, V6 In EASI mode, the sourced (raw) waves are received as: Channel 1 = Vector 1 (A-I) Channel 2 = Vector 2 (A-S) Channel 3 = Vector 3 (E-S) Factory Defaults are II, V2, III, V5. Arrhythmia monitoring is performed only on the primary and secondary leads selected at the Information Center, although you can view and perform ST analysis on all 12 EASI derived leads.
ECG Leads Monitored ECG and Arrhythmia Monitoring 6-17 If you are using ... these leads can be selected at the MX40 and the Information Center 6-wire I, II, III, aVR, aVL, aVF, V1, V2, V3, V4, V5, V6, V7, V8, V9, V3R, V4R, V5R. Sourced (raw) waves are received as: Channel 1 = II Channel 2 = III Channel 3 = Va Channel 4 = Vb Factory Defaults are II, Va = V2, III, Vb = V5. The two chest leads, Va and Vb, can be placed on the patient in any of the V lead positions (V1 through V9, V3R, V4R, V5R). Lead assignment is available at the Information Center. When unassigned, the chest leads use the defaults. Note— The lead label assigned to Vb cannot be selected for Va even though Vb does not appear to be used. When display of the pleth wave is enabled at the Information Center, the second chest lead (Vb) is not available for monitoring. 6-wire (Hexad Mode) I, II, III, MCL, aVR, aVL, aVF, V1-V6. Factory Defaults = Off, V1/V3, V1/V4, V1/V5, V2/V4, V2/V5, V3/V5, V3/V6 Derived leads are labeled, e.g. dV3.
Reconstructed Leads 6-18 ECG and Arrhythmia Monitoring Reconstructed Leads Reconstruction of leads from the sourced wave is defined by the calculations in the following table. EASI reconstructed leads are a linear combination of all three raw EASI leads ECG Lead Clinical Calculations in terms of electrodes 3-wire 5-wire Standard 6-wire I I I LA-RA II (default) II (default) II (default) LL-RA III III (default) III (default) LL-LA - MCL V-LA, where V=C - aVR aVR RA-(LA+LL)/2 - aVL aVL LA-(RA+LL)/2 - aVF aVF LL-(LA+RA)/2 - V (default) V-(RA+LA+LL)/3, where V=C Va Va-(RA+LA+LL)/3, where Va=V2 (default) position Vb Vb-(RA+LA+LL)/3, where Vb =V5 (default) position
Chest Electrode Placement ECG and Arrhythmia Monitoring 6-19 Chest Electrode Placement V1 on the fourth intercostal space at the right sternal border V2 on the fourth intercostal space at the left sternal border V3 midway between the V2 and V4 electrode positions V4 on the fifth intercostal space at the left midclavicular line V5 on the left anterior axillary line, horizontal with the V4 electrode position V6 on the left midaxillary line, horizontal with the V4 electrode position V3R-V6R on the right side of the chest in positions corresponding to those on the left VE over the xiphoid process V7 on posterior chest at the left posterior axillary line in the fifth intercostal space V7R on posterior chest at the right posterior axillary line in the fifth intercostal space For accurate chest electrode placement and measurement, it is important to locate the fourth intercostal space.  To locate the fourth intercostal space: 1 Locate the second intercostal space by first palpating the Angle of Lewis (the little bony protuberance where the body of the sternum joins the manubrium). This rise in the sternum is where the second rib is attached, and the space below this is the second intercostal space. 2 Palpate and count down the chest until you locate the fourth intercostal space.

A (LL) on the left midaxillary line at the same level as the E electrode 3. S (LA) on the upper sternum 4. I (RA) on the right midaxillary line at the same level as the E electrode 5. N (Reference) can be anywhere, usually below the sixth rib on the right hip Make sure that the S and E electrodes line up vertically on the sternum, and that the I, E and A electrodes align horizontally.
6-Wire Placement ECG and Arrhythmia Monitoring 6-23 6-Wire Placement For a 6-lead placement use the positions from the 5-lead diagram above but with two chest leads. The two chest leads, Va and Vb, can be positioned at any two of the V1 to V6 positions shown in the chest electrode diagram below. The default position of Va - the brown lead - is at the V2 position. The default position for Vb - the brown/white lead - is at the V5 position. The lead placement for the Va and Vb lead labels must be appropriate. If your unit uses other precordial leads for Va and Vb, they may be assigned in Unit Settings at the Information Center as defaults for your whole unit, or you may need to assign the new positions on a per-patient basis in the Patient Window at the Information Center. Selecting Positions of Va and Vb Chest Leads The two chest leads for the 6-lead placement can be positioned at any two of the V1 to V9 and V3R, V4R and V5R positions. Select the positions you have used in the Patient Window at the Information Center, so that the chest leads will be correctly labeled.
6-Wire Placement (Hexad) 6-24 ECG and Arrhythmia Monitoring 6-Wire Placement (Hexad) The diagram below shows the Mason-Likar Placement using 6 electrodes. Chest electrodes may be placed in additional positions as presented at the IntelliVue Information Center iX for chest lead pair selection. Note — In Hexad mode, V leads are chosen in pairs at the IntelliVue Information Center iX. 1. RA directly below the clavicle and near the right shoulder 2. LA directly below the clavicle and near the left shoulder 3. RL on the left lower abdomen 4. LL on the right lower abdomen 5. V on the chest, the position depends on your required lead selection. The typical position is V1, although this may vary according based on your hospital’s protocol.  V1 on the fourth intercostal space at the right sternal border  V2 on the fourth intercostal space at the left sternal border  V3 midway between the V2 and V4 electrode positions  V4 on the fifth intercostal space at the left midclavicular line  V5 on the left anterior axillary line, horizontal with the V4 electrode position  V6 on the left midaxillary line, horizontal with the V4 electrode position
Monitoring during Leads Off ECG and Arrhythmia Monitoring 6-25 Monitoring during Leads Off ECG Fallback and Extended monitoring states are supported for the MX40 when the primary and/or secondary leads are in a "Leads Off" INOP condition. Both of these states are entered into after 10 seconds of "Leads Off" in an attempt to maintain monitoring and arrhythmia analysis. ECG Fallback ECG Fallback occurs when the primary lead is in "Leads Off" for 10 seconds and a secondary lead is available. Multilead Analysis If there is a "Leads Off" technical alarm in the primary lead for > 10 seconds, the active secondary lead becomes the primary lead. The arrhythmia algorithm switches the leads on the display, but relearn does not occur. When the "Leads Off" condition is corrected, the leads are switched back to their original state. Single Lead Analysis For single lead analysis, if there are two leads available, the secondary lead is made the primary lead until the "Leads Off" condition is corrected. The arrhythmia algorithm performs a relearn using the available lead. Extended Monitoring If both the primary and secondary leads are in a "Leads Off" condition, the ECG source on the MX40 will switch to any available lead. Relearning will occur in this condition. Fallback for EASI If one of the derived EASI leads is in a technical alarm condition, a flat line is displayed. After 10 seconds, the directly acquired EASI AS, EA, or AI lead, depending on which is available, is displayed. Arrhythmia relearn is performed with transition to or from EASI Fallback monitoring using the available lead(s). Relearning Whenever there is a "Leads Off" condition for more than 60 seconds, the arrhythmia algorithm performs a Relearn using the available leads.
Monitoring during Leads Off 6-26 ECG and Arrhythmia Monitoring Warning Since Relearn happens automatically, if learning takes place during ventricular rhythm, the ectopics can be incorrectly learned as the normal QRS complex. This can result in missed detection of subsequent events of V-Tach and V-Fib. For this reason, you should: 1 Respond promptly to any technical alarm. 2 Ensure that the arrhythmia algorithm is labeling beats correctly.
ST/AR Arrhythmia Monitoring ECG and Arrhythmia Monitoring 6-27 ST/AR Arrhythmia Monitoring ST/AR Arrhythmia Algorithm Indications for Use The ST/AR Arrhythmia Algorithm is indicated for use in instances where the clinician decides to monitor cardiac arrhythmias of adult and pediatric patients and/or the ST segment of adult patients to gain information for treatment, monitor the adequacy of treatment, or to exclude causes of symptoms. How the ST/AR Algorithm Works ST/AR multi-lead analysis is performed on the user-selected primary and secondary leads. If only one lead is available for multilead, ST/AR analysis is performed on the single available lead. Arrhythmia analysis consists of several steps: 1 The ECG signal is pre-processed to filter out baseline wander, muscle artifact, and signal irregularities. In addition, if the Paced status = On, pace pulses are detected then rejected from the processing to avoid seeing them as QRS beats. 2 Beat detection to locate the QRS complexes for further analysis. 3 Feature measurement such as R-wave height, width, and timing. 4 Beat classification. Templates are created and are matched to incoming beats, and the appropriate beat label is determined. 5 Atrial Fibrillation Detection. Analyzes the RR intervals and P waves. 6 Ventricular Fibrillation Detection. Looks for a flutter or sinusoidal wave pattern in both ECG channels 7 Rhythm and alarm detection. Beat labels are used to produce the values and events needed to generate rhythms and alarms. Working in parallel with beat detection and classification, a separate detector examines continuously for ventricular fibrillation, asystole, and noise. The quality of the ECG signal is important for accurate arrhythmia analysis. The section below provides guidelines for optimizing signals for arrhythmia analysis.
ST/AR Arrhythmia Monitoring 6-28 ECG and Arrhythmia Monitoring For additional information on the ST/AR Algorithm, refer to the Arrhythmia Monitoring ST/AR Algorithm Application Note. Aberrantly-Conducted Beats As P-waves are not analyzed, it is difficult and sometimes impossible for the monitor to distinguish between an aberrantly-conducted supraventricular beat and a ventricular beat. If the aberrant beat resembles a ventricular beat, it is classified as ventricular. You should always select a lead where the aberrantly-conducted beats have an R-wave that is as narrow as possible to minimize incorrect calls. Ventricular beats should look different from these 'normal beats'. Instead of trying to select two leads with a narrow R-wave, it may be easier to just select one lead and use single lead arrhythmia monitoring. Extra vigilance is required by the clinician for this type of patient. Atrial Fibrillation Alarm The MX40 performs atrial fibrillation analysis using information about the RR irregularity, PR interval variability, and P-wave variability. In order to generate an Afib alarm the following criteria must be detected for 1 minute:  normal beat RR intervals must be irregular  PR interval deviation must be large  P-wave region must not match well Atrial fibrillation analysis is only available for adult patients and atrial fibrillation detection cannot be performed on PVCs or Paced beats. An *End AFIB alarm will occur when no atrial fibrillation waveform is detected for a configured delay time. Since most atrial flutters have regular RR intervals, they cannot be detected by the atrial fibrillation algorithm. An *AFIB alarm can be falsely detected in the presence of:  sinus arrhythmia  muscle noise, or  electrode motion artifact
ST/AR Arrhythmia Monitoring ECG and Arrhythmia Monitoring 6-29 Intermittent Bundle Branch Block Bundle branch and the other fascicular blocks create a challenge for the arrhythmia algorithm. If the QRS during the block changes considerably from the learned normal, the blocked beat may be incorrectly classified as ventricular, causing false PVC alarms. You should always select a lead where the bundle branch block beats have an R-wave that is as narrow as possible to minimize incorrect calls. Ventricular beats should look different from these 'normal beats'. Instead of trying to select two leads with a narrow R-wave, it may be easier to just select one lead and use single lead arrhythmia monitoring. Extra vigilance is required by the clinician for this type of patient. ECG and Arrhythmia Alarm Overview The ECG and arrhythmia alarms available depend on which measurements are switched on, and the arrhythmia option enabled for your MX40.  Cardiotach alarms are available when HR is on and the active alarm source is ECG, but arrhythmia s switched off.  Basic arrhythmia alarms are available when Arrhythmia is switched on.  Enhanced arrhythmia alarms are available when Arrhythmia is switched on and the Enhanced Arrhythmia option has been enabled for your MX40. To check your enabled settings, view the Standby screen.

Therefore, you may see slight differences between the two, even though the alarm settings and limits are the same. Using ECG Alarms At the Information Center, ECG alarms can be switched on and off and the high and low alarm limits changed just like other measurement alarms, as described in the Alarms chapter. Special alarm features which apply only to ECG are described here. Extreme Alarm Limits for Heart Rate The extreme rate alarms, Extreme Tachy and Extreme Brady, are set at the Information Center by adding a set value (the D value) to the high and low alarm limits.
ST/AR Arrhythmia Monitoring ECG and Arrhythmia Monitoring 6-31 1. Extreme Brady Limit 2. Low Limit 3. High Limit 4. Extreme Tachy Limit 5. Extreme Brady (D value) 6. Extreme Tachy (D value) You need to know which value has been configured for your monitor. Changing the high and low alarm limits automatically changes the extreme alarm limits within the allowed range. Arrhythmia Alarm Settings Some arrhythmia alarms can be turned off at the Information Center depending its configuration. They are: Non-Sustain VT, Vent Rhythm, Run PVCs, Pair PVCs, R-On-T PVC, V.Bigeminy, V.Trigeminy, Multif.PVCs, Pause, SVT, HR High, HR Low Irregular HR (IHR), Missed Beat, PVCs/min, Pacer Not Capture, Pacer Not Pacing,and Afib. Alarms that have been turned off at the Information Center will appear as off in the Arrhythmia menu of the MX40, but they are not accessible, nor can you change limits locally. Yellow Arrhythmia Alarms Yellow arrhythmia alarms are short yellow alarms specific to arrhythmia-related patient conditions. Depending on your Information Center configuration, they may be shown with one or two stars. The heart rate alarms (High HR and Low HR) can be configured as short yellow or standard yellow alarms. When they are standard yellow alarms they exist independently of the other arrhythmia alarms and no timeout periods apply. Warning When arrhythmia analysis is on, all yellow ECG and arrhythmia alarms are short yellow alarms (one-star). This means that the alarm tones (if volume is on) are active for six seconds only, after which the blinking numeric and the alarm message remain for up to three minutes. The only exception to this are the HR High and Low alarms which can be configured as standard yellow alarms. Red alarms behave as usual.
ST/AR Arrhythmia Monitoring 6-32 ECG and Arrhythmia Monitoring Viewing Arrhythmia Waves  To view arrhythmia beat labels: 1 Go to the Setup ECG menu. 2 Select Arrhythmia. 3 Change Annotate Arrhy from Off to On. Beat labels will be annotated above the ECG wave and Delayed will appear beside it.  To return to the normal ECG primary lead display: 1 Select Annotate Arrhy. 2 Change to Off. 3 Exit from the Setup ECG menu. Arrhythmia Beat Labels Arrhythmia beat labels tell you how the monitor is classifying beats. N = Normal V = Ventricular Ectopic S = Supra-ventricular Premature P = Paced ' = Pacer spike " = Biventricular Pacer Spike L = Learning patient's ECG A = Artifact (noisy episode) ? = Insufficient information to classify beats I = Inoperative condition (e.g., LEADS OFF) M = Pause or missed beat

This "learning" process uses the 15 first valid beats (for example, free from noise) encountered during the learning phase. While the system is learning the complex, the delayed arrhythmia wave displays the beat label "L".
ST/AR Arrhythmia Monitoring ECG and Arrhythmia Monitoring 6-35 Learning Phase A learning phase involves the system learning the patient’s dominant complexes. During a learning phase:  Alarm timeout periods are cleared.  Stored arrhythmia templates are cleared.  Asystole, Vfib, and HR alarms (when there are enough beats to compute the HR) are active.  All other alarms are not active. Single Lead Analysis If single lead analysis is selected, the arrhythmia system begins learning whenever:  ECG monitoring is initiated.  The Relearn Arrhy control is activated. See Initiating Arrhythmia Relearning Manually p. 6-36.  The ECG Lead or Lead Label is changed manually, or when Fallback occurs. See Fallback.  A "LEADS OFF" INOP condition (that has been active for >60 seconds) ends.  When the MX40 re-associates with the Information Center. Multilead Analysis If multilead analysis is selected, the arrhythmia system begins a learning on both leads whenever:  ECG monitoring is initiated.  The Relearn Arrhy control is activated (see Initiating Arrhythmia Relearning Manually p. 6-36).  There has been a Leads Off INOP condition (that has been active for >60 seconds) for both leads, and the condition ends in either lead.  When the MX40 re-associates with the Information Center. Multilead Analysis With Changes in One Lead Since the arrhythmia system uses more than one lead for analysis, if there is a change in one lead, the system does a relearn only on the affected lead. This happens whenever:  An ECG lead or label is changed.
ST/AR Arrhythmia Monitoring 6-36 ECG and Arrhythmia Monitoring  A Leads Off INOP condition (that has been active for >60 seconds) ends. Note — During this learning phase the system will continue monitoring using the operative lead. Therefore, the delayed arrhythmia wave is not labeled "L". In addition:  Alarm timeout periods are maintained.  Stored arrhythmia templates are maintained for the operative lead.  All alarms turned on are active. EASI ECG Monitoring Whenever there is an INOP condition, the arrhythmia algorithm performs a Relearn, using the available lead. Warning Since Relearn happens automatically, if learning takes place during ventricular rhythm, the ectopics may be incorrectly learned as the normal QRS complex. This may result in missed detection of subsequent events of V-Tach and V-Fib. For this reason, you should: 1 Respond to the INOP message (for example, re-connect the electrode(s). 2 Ensure that the arrhythmia algorithm is labeling beats correctly. Initiating Arrhythmia Relearning Manually To initiate relearning manually, in the Setup ECG menu, select Relearn Arrhy.  While the monitor is learning, if annotate arrhythmia is On, the delayed arrhythmia wave displays the beat label L.  Next, the monitor determines the dominant rhythm. The beats are labeled N. After relearning is complete, you should check the delayed arrhythmia wave to ensure that the algorithm is labeling the beats correctly. See Arrhythmia Beat Labels p. 6-32. If beats are still not classified correctly, check that the ECG is optimized for arrhythmia monitoring. You may need to select a different lead or change the electrodes or electrode positions if there is excessive noise, unstable voltage, low amplitude, or large P- or T-waves.
ST/AR ST Analysis Algorithm ECG and Arrhythmia Monitoring 6-37 ST/AR ST Analysis Algorithm Introduction The intended use of the ST/AR ST Analysis algorithm is to monitor an adult patient’s ECG for ST segment elevation or depression and produce events/alarms for all possible ECG leads. The ST Analysis algorithm is capable of monitoring paced and non-paced adult patients. The ST/AR ST algorithm monitors ST segment elevation or depression for each available telemetry ECG lead and produces events/alarms simultaneously. Note—The ST Analysis algorithm does not analyze ventricularly paced or ventricular ectopic beats. Warning This device provides ST level change information; the clinical significance of the ST level change information needs to be determined by a physician. ST values update with every measurement period and enunciate, depending upon the severity of the change, events and alarms as they are detected. The ST/AR ST algorithm is approved for use only with adult non-paced and atrially-paced patients. Caution Some clinical conditions may make it difficult to achieve reliable ST monitoring, for example:  if you are unable to select a lead this is not noisy  if arrhythmias such as atrial fib/flutter are present, which may cause an irregular baseline  if the patient is continuously ventricularly paced  if the patient has left bundle branch block
ST/AR ST Analysis Algorithm 6-38 ECG and Arrhythmia Monitoring The Measurements Overview The ST/STE measurement for each beat complex is the vertical difference between two measurement points. The isoelectric point provides the baseline for both measurements. The ST measurement uses the isoelectric point and the ST point. The ST point is positioned with reference to the J-point. The STE measurement uses the isoelectric point and the J point. 1. R-wave peak at 0 msec 2. J point 3. Difference = ST value 4. ST measurement point. Default = J+60 msec 5. Isoelectric point. Default = -80 msec 6. P 7. Q 8. S 9. T You can manually adjust the ST/STE measurements on the Information Center's Measurements application. Turning ST or STE On and Off ST and STE analysis can be turned on and off independently. You would turn ST/STE monitoring off if:  You are unable to get any lead that is not noisy.  Arrhythmias such as atrial fib/flutter cause irregular baseline.  The patient is continuously ventricularly paced.  The patient has left bundle branch block.  To turn all ST or STE monitoring on or off at the IntelliVue Information Center iX: 1 Select the Measurements ST page. 2 Click the I/O ST or I/O STE Analysis button to toggle ST or STE Analysis on or off as appropriate.
ST/AR ST Analysis Algorithm ECG and Arrhythmia Monitoring 6-39  To turn ST monitoring on or off at the IntelliVue Information Center Release N: 1 From the Patient Window, click the All Controls button. 2 From the All Controls Window, click the ST Setup button. 3 From the ST Setup Window, click ST On/Off as appropriate. Displayed ST Data ST data displays as values in the Patient Sector and Patient Window at the Information Center. At the MX40, three ST values can be displayed below the ECG wave. A positive value indicates ST segment elevation; a negative value indicates ST segment depression. You can view ST data at the MX40 if ST is assigned to a numeric area. Up to 3 values can display in the assigned space. If more than three values area available, the last value will rotate. Displayed STE Data STE Data can only be displayed in the Measurements application STE page at the Information Center iX. Note — ST/STE data and alarms are only displayed at the MX40 when operating with IntelliVue Information Center iX. ST Lead Groups ECG Leads are clinically grouped as follows: ST Lead Group ECG Leads Inferior II, III, aVF Lateral I, aVL, V5, V6 Antero-lateral I, aVL, V4, V5, V6 Anterior V1, V2, V3, V4 Septal V1, V2, V3 Right V3R, V4R, V5R Posterior V7, V8, V9 You can change the group displayed using the ST Views menu.
ST/AR ST Analysis Algorithm 6-40 ECG and Arrhythmia Monitoring Derived 12 Lead ECG In view of the high degree of redundancy among the standard 12-lead ECG leads, it is quite conceivable that a more practical leadset with a smaller number of judiciously chosen leads can be used to reconstruct the missing leads. For Hexad derived 12-lead the-6 electrode configuration is the feasibility of deriving additional chest leads if the two chest electrodes are placed in several pre-specified standard precordial locations. Using a standard 5-electrode set in EASI lead placement you can monitor up to 12 standard ECG leads simultaneously and continuously at the bedside. EASI provides a monitoring method for trending ST segment changes that can provide an early indication of ischemia. Caution Derived ECG and their measurements are approximations to the standard ECG, and should not be used for diagnostic interpretation. EASI ST Analysis With EASI monitoring, ST analysis is performed on up to 12 leads, and an additional value of ST index is calculated and displayed. Assessment of EASI-derived 12-lead ST measurement is recommended for adult patients that meet the following parameters:  Ages: 33-82 years  Heights: 147 to 185 cm (58 to 73 in)  Weights: 53 to 118 kg (117 to 261 lbs)  Height to Weight Ratios: 1.41 to 2.99 cm/kg (0.25 to 0.54 in/lb) For additional information on ST monitoring, refer to the ST Segment Monitoring Application Note, Part Number 452296278611. ST values are presented in the patient sector and Patient Window for EASI derived leads along with STindx (ST Index). STindx is a summation of three ST segment measurements, using the leads that can indicate ST segment changes in the different locations of the heart:  anterior lead V2  lateral lead V5  inferior lead aVF
ST/AR ST Analysis Algorithm ECG and Arrhythmia Monitoring 6-41 HEXAD ST Analysis When operating with the IntelliVue Information Center iX, the optional Hexad algorithm generates a Mason-Likar 12-lead ECG from a 6-wire leadset (including four limb electrodes and two chest electrodes) placed according to the Mason-Likar 6-electrode placement. To generate a derived 12-lead ECG using this configuration, 8 out of the 12 leads are directly acquired (I, II, III, aVR, aVL, aVF and the two directly-recorded V leads) and only 4 precordial leads need to be derived. This means that 8 of 12 are identical to the 12 leads acquired using a full set of 10-wire standard ECG lead set. For more information refer to the 12 Lead ECG Monitoring Using a Reduced Lead Set Application Note, Part Number 452296278591. ST Alarms ST Alarms are yellow alarms. They are announced after exceeding alarm limits for one minute. ST Alarm Limits can only be set at the Information Center. Each ST lead has its own alarm limit. ST alarms are triggered when an ST value exceeds its limit for more than one minute. Turning ST Alarms off turns off alarms for all ST leads. STE Alarms The STE Alarm is a yellow alarm. It is announced after exceeding alarm limits for one minute. It can be turned on and off at the Information Center, however its limits are not adjustable. The STE alarm limits are gender specific and can be set individually for limb leads, V2/V3 leads, and V1/V4/V5/V6 leads. The default values, for example on V2 and V3 1.5 mm for females and 2.0 mm for males, are based on the recommendations from the American Heart Association and American College of Cardiology. The ST Elevation measurements with automated J-point determination generate ST Elevation alarms, in addition to the ST measurements at the user-defined ST point (J+offset), which may be useful for ST depression alarms. When ST and STE analysis are both in use, this may result in redundant alarms for ST elevations. Because of the different measurement points, there may be different values obtained. Thus there could be an ST alarm and an STE alarm but the STE alarm may announce sooner based upon the values obtained.
QT Interval Monitoring 6-42 ECG and Arrhythmia Monitoring QT Interval Monitoring Of special concern for QT monitoring is the administration of QT prolonging drugs to patients identified with risk factors for Torsade de Pointe. Females, older patients and patients with bradycardia, impaired left ventricular function (ischemia, left ventricular hypertrophy), hypokalemia and hypomagnesemia are in this increased risk category. QT interval monitoring can assist in the detection of prolonged QT interval syndrome. The QT interval in an ECG lead is the time interval from the onset of the earliest deflection in the QRS complex to the end of the T wave. For patients being monitored by the MX40, the Information Center measures the QT interval once every minute during startup, during the learning phase and on lead mode change. After that the Information Center updates the QT values every five minutes. The QT interval has an inverse relationship to heart rate. Faster heart rates shorten the QT interval and slower heart rates prolong the QT interval. To correct the QT interval for heart rate the Information Center uses the Bazett correction formula by default. Your system, however, may be set up to use the Fridericia correction formula as an alternative. The heart rate corrected QT interval is abbreviated as QTc. Note — When operating with the IntelliVue Information Center Release N or earlier, QT Data is not displayed at the MX40
QT Interval Monitoring ECG and Arrhythmia Monitoring 6-43 Intended Use The intended use of the ST/AR QT/QTc analysis is for use by the physician in the risk assessment process indicated for pediatric and adult patients with and without symptoms of arrhythmia. QT measurement is intended to be used by qualified health professionals in hospital or clinical environments. Composite QT (single or multi-lead derived) measures the interval only and is not intended to produce any interpretation or diagnosis of those measurements. Additional information regarding QT monitoring can be found in the QT Interval Monitoring Application Note, Part Number 452296278601. Warning The device provides QT and QTc interval change information; the clinical significance of the QT and QTc interval change information should be determined by a clinician. How the QT Analysis Algorithm Works The Information Center measures the QT values once every minute during startup. Subsequently, the Information Center updates the QT values every five minutes. Normal or atrial paced beats and beats with a similar morphology are averaged to form a representative waveform for further processing. Normal beats followed by a premature QRS will be excluded from the measurements to prevent the premature beat from obscuring the end of the T-wave. If the algorithm cannot form a representative waveform, for example because the morphology of the beats is too varied, the Information Center generates a Cannot Analyze QT INOP when it detects two consecutive invalid 5 minute values. This is also the case if normal beats have been falsely labeled so that the algorithm does not have enough valid beats to make QT measurements. No QT value is calculated if the QT-HR is >150 bpm (Adult) or >180 bpm (Pediatric). Because of the different algorithm approaches, a QT/QTc measurement from a diagnostic 12-lead program may differ from the realtime measurement. For QT interval monitoring to be effective, basic or enhanced arrhythmia monitoring must be on.
QT Interval Monitoring 6-44 ECG and Arrhythmia Monitoring Adjusting QT Settings For patients being monitored by the MX40, you can turn QT Monitoring on/off and adjust QT settings at the IntelliVue Information Center.  To turn QT Monitoring on/off at the IntelliVue Information Center Release N: 1 From the Patient Window, click the All Controls button. 2 From the All Controls Window, click the QT Setup button. 3 From QT Setup, click the QT Analysis On checkbox. QT analysis is on when a checkmark displays in the check box. When the QT measurement is on, a QT status message is displayed in the QT Setup window, along with the current values for QT, QTc, dQTc and QT-HR. The lead labels indicating the leads used to calculate the baseline and current values also appear.  To turn QT Monitoring on/off at the IntelliVue Information Center iX: 1 Select the Measurements button from the Main Setup Window. 2 From the Measurements Window, select QT. 3 Click the I/O QT Analysis button to toggle on or off as appropriate. The table below provides descriptions for each of the QT measurement descriptions. Measurement Definition QT QT interval in milliseconds. The QT interval is the time between the beginning of the Q-wave and the end of the T-wave. QTc QTc represents the heart rate corrected QT interval. By default, the Information Center uses the Bazett correction formula to correct the QT interval for heart rate. Your system, however, may be set up to use the Fridericia correction formula. dQTc The difference between the current QTc value and the QTc baseline value. QT-HR The heart rate used to calculate QTc Note—Turning QT analysis off does not clear the baseline value. This allows you to turn QT analysis off during prolonged arrhythmias, such as bigeminy, without losing the baseline.
QT Interval Monitoring ECG and Arrhythmia Monitoring 6-45 Limitations for QT Monitoring Some conditions may make it difficult to achieve reliable QT monitoring. When this occurs the CANNOT ANALYZE QT INOP message displays at the Information Center, along with a QT STATUS message. Some conditions that may make reliable QT monitoring difficult include:  T-Wave Detection Limitations. Flat T-wave, atrial Fibrillation or atrial Flutter and prominent U-waves can make QT monitoring difficult. For these cases you should select All as the QT Lead on the QT window. The Information Center will use the lead or leads that have a T-wave with sufficient amplitude and can be detected. Alternatively select a single lead with a good T- wave amplitude and no visible flutter activity and without a predominant U-wave or P-wave.  QRS Changes QRS changes such as widened QRS can affect QT monitoring. If a long QTc is observed verify that is not caused by QRS widening.  Rhythm and Rate Limitations Rhythm and rate limitations such as high heart rate (> 150 beats/min for adult patients or > 180 beats/min for pediatric or neonatal patients), paced rhythm and bigeminy rhythm can make reliable QT monitoring difficult. If rhythm is sustained you may want to consider turning QT interval monitoring off.

Pulse Rate Measurement .......................................................................... 7-2 Displaying the Pulse Rate Measurement at the MX40 ......................... 7-3
Pulse Rate Measurement 7-2 Monitoring Pulse Rate Pulse Rate Measurement The pulse rate measurement counts the arterial pulsations that result from the mechanical activity of the heart in beats per minute (bpm). The pulse rate is derived from the SpO2 measurement. Displayed results can range from 30 to 300 bpm. There is no alarm function for pulse rate. The pulse numeric is displayed at the Information Center only when SpO2 is being measured continuously. Manual measurements are displayed at the MX40 with a time stamp. There are no alarms associated with the pulse measurement. Pulse is turned on in the Telemetry Setup window at the IntelliVue Information Center Release N or earlier and using the Measurements/SpO2 page at the IntelliVue Information Center iX.

Respiration Rate Measurement 8-2 Monitoring Respiration Rate (Resp) Respiration Rate Measurement For the respiratory measurement (Resp), the MX40 measures the thoracic impedance between two ECG electrodes on the patient's chest. Changes in the impedance due to thoracic movement produce the Resp waveform on the display. The MX40 counts the waveform cycles to calculate the respiration rate (RR).The waveform size can be set using the Setup Resp menu which is displayed when you touch the Resp measurement area. Settings for Resp On/Off, alarms, alarm limits and apnea time are defined at the Information Center. When the ECG measurement is turned off, the Resp measurement is also turned off. Note — The Resp measurement is not available when the MX40 is wirelessly connected to MP5T, MP2, or X2 patient monitors. When not connected wirelessly to a monitor and Resp is being measured, the message SRR Unavailable with Resp is displayed on the MX40.
Resp Safety Information Monitoring Respiration Rate (Resp) 8-3 Resp Safety Information Warning Apnea The respiration measurement does not recognize obstructive and mixed apneas. It only indicates an alarm when a pre-adjusted time has elapsed since the last detected breath. Resp Accessories To monitor respiration, use only non-OR ECG accessories as listed in the Accessories Appendix. Rate Adaptive Pacemakers Implanted pacemakers which can adapt to the Minute Ventilation rate may occasionally react on the Impedance measurement used by devices for the determination of the Resp value and execute pacing with the maximum programmed rate. Turning off the Resp measurement can prevent this.
Lead Placement for Monitoring Resp 8-4 Monitoring Respiration Rate (Resp) Lead Placement for Monitoring Resp Correct patient skin preparation techniques for electrode placement are important for Resp measurement. See Connecting and Positioning ECG Electrodes p. 6-6. The Resp measurement uses the standard MX40 patient cable. You can use 3-wire, 5-wire, or 6-wire leadsets, using either Standard or EASI placement. Optimizing Lead Placement for Resp If you want to measure Resp and you are already measuring ECG, you may need to optimize placement of the two electrodes between which Resp will be measured. Repositioning ECG electrodes from standard positions, especially when you are using EASI placement, results in changes in the ECG waveform and may influence ST and arrhythmia interpretation. Cardiac Overlay Cardiac activity that affects the Resp waveform is called cardiac overlay. Cardiac overlay happens when the Resp electrodes pick up impedance changes caused by the rhythmic blood flow. Correct electrode placement can help to reduce cardiac overlay. Avoid the liver area and the ventricles of the heart in the line between the respiratory electrodes. Abdominal Breathing Some patients with restricted chest movement breathe mainly abdominally. In these cases, you may need to place the left leg electrode on the left abdomen at the point of maximum abdominal expansion to optimize the respiratory wave.
Displaying Resp on the MX40 Monitoring Respiration Rate (Resp) 8-5 Displaying Resp on the MX40  To display the Resp waveform and/or numeric: 1 At the IntelliVue Information Center iX, select the Measurements button from the Main Window. 2 From the Measurements Window, select Resp. 3 Click the I/O Resp button to toggle on or off as appropriate. 4 At the MX40, select a waveform area to display the Resp waveform. 5 The Change Wave menu is displayed. 6 From the Change Wave menu, select Resp. 7 Select any measurement numeric to change to display the Resp numeric. 8 Select Change Numeric (it may be necessary to scroll down).

SpO2 Monitoring 9-1 9. SpO2 Monitoring This section provides an introduction to the SpO2 measurement and its application. SpO2 Safety Information ........................................................................... 9-2 Pulse Oximetry Measurement ................................................................. 9-5
SpO2 Safety Information 9-2 SpO2 Monitoring SpO2 Safety Information Warnings  Always confirm monitor observations with clinical observation of the patient before administering interventions.  Prolonged, continuous monitoring can increase the risk of changes in skin characteristics, such as irritation, reddening, blistering or pressure necrosis, particularly on patients with impaired perfusion and varying or immature skin morphology. Specific attention must be given to sensor site inspection for changes in skin quality, proper optical path alignment and attachment. Check the application site at regular intervals and change the site if any compromise in skin quality should occur. More frequent checking can be required due to an individual patient's condition.  Injected dyes such as methylene blue or intravascular dyshemoglobins such as methemoglobin and carboxyhemoglobin can lead to inaccurate (over-estimated) measurements.  Interference leading to inaccurate measurements can be caused by:  High levels of ambient light (Hint: cover application site with opaque material)  Electromagnetic interference  Excessive patient movement and vibration.  This equipment is not suitable for use in the presence of a flammable anesthetic mixture or oxygen concentrations greater than 25% (or partial pressures greater than 27,5 kPa /206.27 mmHg).  Disposable SpO2 sensors can be damaged and lead to patient harm if they become wet. Wet sensors must be replaced immediately.  To avoid venous pulsation, obstructed circulation, pressure marks, pressure necrosis, artifacts and inaccurate measurements, make sure that the sensor is not too tight. If the sensor is too tight, because the application site is too large or becomes too large due to edema, excessive pressure may be applied. This can result in venous congestion distal from the application site, leading to interstitial edema, hypoxia and tissue malnutrition.  Inspect the sensor application site every 2 to 3 hours to ensure skin integrity, correct optical alignment, and circulation distal to the sensor site. Move the sensor application site every four hours, or more often if circulation or skin integrity is compromised.
SpO2 Safety Information SpO2 Monitoring 9-3  At elevated ambient temperatures, be careful with measurement sites that are not well perfused, because this can cause severe burns after prolonged application. All listed sensors operate without risk of exceeding 41o C on the skin if the initial skin temperature does not exceed 37o C.  Avoid placing the sensor on extremities with an arterial catheter or intravascular venous infusion line.  Sensors connected to the MX40 but not applied to the patient, can produce an error measurement. To avoid misdiagnosis, ensure the sensor is properly applied to the patient. Cautions  If you measure SpO2 on a limb that has an inflated NBP cuff, a non-pulsatile SpO2 INOP (SpO2T NO PULSE) can occur. If the monitor is configured to suppress this alarm, there may be a delay of up to 60 seconds in indicating critical patient status, such as sudden pulse loss or hypoxia.  Do not use OxiCliq disposable sensors in a high humidity environment, such as an incubator, or in the presence of fluids, which may contaminate sensor and electrical connections causing unreliable or intermittent measurements. Do not use disposable sensors on patients who have allergic reactions to the adhesive.  When the MX40 is connected to a patient monitor using the MX40 / IntelliVue Patient Monitor Adapter Cable, (p/n 989803172211), the SpO2 sensor must be directly connected to the patient monitor to monitor SpO2.  Do not use more than one extension cable (M1941A). See Appendix A, Accessories, for information on which sensors cannot be used with an extension cable.  Position the sensor cable away from power cables to avoid electrical interference. SpO2 Information for the User The pulse oximeter is calibrated to indicate functional oxygen saturation (fractional oxyhemoglobin), and displayed results can range from 0 to 100%.
SpO2 Safety Information 9-4 SpO2 Monitoring A 10 second averaging filter is used in the calculation of the result. Displayed results are typically updated every second, but the update period can be automatically delayed by up to 30 seconds in the presence of noise. Note — The averaging filter time period is configurable at the IntelliVue Information Center iX (default = 10 seconds). Physiological SpO2 alarm signals will be generated. For adult patients, the SpO2 low limit can be set between 50 and 99% inclusive, in 1% increments, and the SpO2 high alarm limit can be set between 51 and 100% inclusive, in 1% increments. For pediatric patients, the SpO2 low limit can be set between 30 and 99% inclusive, in 1% increments, and the high alarm limit can be set between 31 and 100% inclusive, in 1% increments. The maximum delay between the physiological alarm condition and alarm signal generation is 25 seconds. Pulse rate is also derived from the pulsatile SpO2 measurement, and displayed results can range from 30 to 300 bpm. There is no alarm function for pulse rate. The pleth wave is auto-scaled to maximum display size. It decreases only when the signal quality becomes marginal. Pleth wave size is NOT directly proportional to the pulse volume.
Pulse Oximetry Measurement SpO2 Monitoring 9-5 Pulse Oximetry Measurement The MX40 supports an SpO2 sensor connection using Fourier Artifact Suppression Technology (FAST). The FAST algorithm overcomes many of the issues associated with traditional pulse oximetry such as sensitivity to patient movement and intense ambient light. The algorithm offers improved motion artifact rejection as well as performance improvements for patients with low perfusion. SpO2 can be measured continuously, where a value is sent to the Information Center every second, or as a single, individual Manual measurement. The Manual measurement will be removed from the Information Center display after 1 hour. The SpO2 parameter measures the arterial oxygen saturation, that is, the percentage of oxygenated hemoglobin in relation to the total hemoglobin. If, for example, a total of 97% of the hemoglobin molecules in the red blood cells of the arterial blood combine with oxygen, then the blood has an oxygen saturation of 97%. The SpO2 numeric that appears on the monitor will read 97%. The SpO2 numeric indicates the percentage of hemoglobin molecules which have combined with oxygen molecules to form oxyhemoglobin.  The oxygen saturation is measured using the pulse oximetry method. This is a noninvasive method of measuring the arterial hemoglobin oxygen saturation. It measures how much light, sent from light sources on one side of the sensor, travels through patient tissue (such as a finger or an ear), to a receiver on the other side of the sensor.  The amount of light passing through depends on many factors, most of which are constant, such as tissue or venous blood. However one of the factors, the blood flow in the arterioles, varies with time because it is pulsatile. This measurement principle is used to derive the SpO2 measurement. The numeric that is displayed is the oxygen saturation of the arterial blood - the measurement of light absorption during a pulsation. Correct placement of the sensor is essential for accurate measurements. Note—Because pulse oximeter equipment measurements are statistically distributed, only about two-thirds of pulse oximeter equipment measurements can be expected to fall with ± Arms of the value measured by a CO-oximeter.
Pulse Oximetry Measurement 9-6 SpO2 Monitoring SpO2 Sensors Familiarize yourself with the instructions for use supplied with your sensor before using it. In particular, check that the sensor being used is appropriate for your patient category and application site. See Appendix A, Accessories, for a complete listing of supported sensors for the MX40. Selecting an SpO2 Sensor Warning  Use only Philips-approved accessories. Use of product accessories (patient cables, SpO2 sensors, etc.) other than those specified in this manual may lead to patient injury or result in increased electromagnetic emissions or decreased immunity of the product.  Reuse: Never reuse disposable sensors, accessories and so forth that are intended for single use, or single patient use only.  Packaging: Do not use a sterilized accessory if the packaging is damaged.  Do not use disposable sensors on patients who exhibit allergic reactions to the adhesive.  When the specified Nellcor® sensors are used, the application must be consistent with the sensor manufacturer's own guidelines. Philips reusable sensors in adult, pediatric and infant (an alternative for use on adult patients only) models can be used, as well as Philips and Nellcor® disposable sensors. Caution Do not use OxiCliq disposable sensors in a high humidity environment, or in the presence of fluids. These can contaminate sensor and electrical connections, and thereby cause unreliable or intermittent measurements. The following table will help you in selecting the correct sensor type.
Pulse Oximetry Measurement SpO2 Monitoring 9-7 Sensor Type When to Use Reusable You can use reusable sensors on different patients after cleaning and disinfecting them. For care and cleaning instructions, see the instructions accompanying the sensors. Reusable sensors should be changed to another site every four hours or in accordance with your clinical practice guidelines. See the Directions for Use supplied by Nellcor® Incorporated for instructions on preparation and application of reusable sensors. Disposable Use disposable sensors only once and then discard. However, you can relocate them to a different patient-site if the first location does not give the desired results. Do not reuse disposable sensors on different patients. Note — See the Instructions for Use supplied by Nellcor® Incorporated for instructions on preparation and application of disposable sensors. Sensor Application Safety Information Warning Failure to apply a sensor properly can reduce the accuracy of the SpO2 measurement.  Loose/Tight sensor: If a sensor is too loose, it can compromise the optical alignment or fall off. If it is too tight, for example because the application site is too large or becomes too large due to edema, excessive pressure can be applied. This can result in venous congestion distal from the application site, leading to interstitial edema, hypoxia and tissue malnutrition.  Skin irritations or ulcerations can occur as a result of the sensor being attached to one location for too long. To avoid skin irritations and ulcerations, inspect the sensor application site every 2-3 hours, and change the application site at least every 4 hours or according to clinical practice guidelines.  Venous Pulsation: Do not apply sensor too tightly as this results in venous pulsation, which can severely obstruct circulation and lead to inaccurate measurements.
Pulse Oximetry Measurement 9-8 SpO2 Monitoring  Ambient Temperature: Never apply an SpO2 sensor at ambient temperatures above 37 oC (99 oF) because this can cause severe burns after prolonged application.  Extremities to Avoid: Avoid sites distal to NBP cuff, intra-arterial line, or intravascular venous infusion line. Applying the Sensor 1 Follow the SpO2 sensor's Instructions for Use, adhering to all warnings and cautions. 2 If necessary, remove colored nail polish from the application site. 3 Apply the sensor to the patient. The application site should match the sensor size so that the sensor can neither fall off, nor apply excessive pressure. 4 Check that the light emitter and the photodetector are directly opposite each other. All light from the emitter must pass through the patient's tissue. Connecting SpO2 Cables The sensor cable is either directly connected to the blue SpO2 connector on the MX40 patient cable or is connected to an adapter cable that is then connected to the MX40 SpO2 connector. Tone Modulation Indication The pulse signal tone is controlled by the setting in the SpO2 Tone Modulation menu. Note — Tone Modulation Indication is only available when operating in Continuous mode. It is not available when operating in Manual or Auto mode. Signal Quality Indicator The SpO2 numeric is displayed together with a signal quality indicator which gives an indication of the reliability of the current values. The level to which the triangle is filled shows the quality of the signal. The signal quality is at a maximum when the triangle is completely filled.
Pulse Oximetry Measurement SpO2 Monitoring 9-9 Measuring SpO2 Warning  Removal of the SpO2 sensor from the MX40 patient cable during Continuous SpO2 monitoring results in a "No Sensor" technical alarm. Silencing this alarm turns the SpO2 measurement off, however the SpO2 module is still operating in the background and consuming battery power. If you do not intend to resume continuous SpO2 monitoring, change to Manual mode. There is no technical alarm for a "No Sensor" condition in Manual mode.  If you measure SpO2 on a limb that has an inflated NBP cuff, a non-pulsatile SpO2 technical alarm can occur. If the monitor is configured to suppress this alarm, there can be a delay of up to 60 seconds in indicating critical patient status, such as hypoxia. SpO2 measurements can be made manually on an as-needed basis in Manual mode, continuously in Continuous mode, or automatically in Auto mode (IntelliVue Information Center iX only), depending on your MX40 configuration. While operating in Continuous mode, you can also measure pulse, and display the pleth wave on the MX40 and at the Information Center. The SpO2 parameter is turned on/off at the MX40 or by a control from the Information Center. SpO2 monitoring consumes considerable electrical energy. The battery power must be at least 10% full in order to make SpO2 measurements. To resume the SpO2 measurement after it has been turned off, touch the blank measurement area and select SpO2 to turn it back on. Note — Before disabling SpO2 at the Information Center, acknowledge any active alarms at the MX40. Setting the SpO2 mode can be done at the Information Center or at the MX40.  To select the measurement mode at the MX40: 1 In SpO2 Setup, select Mode. 2 Select Continuous, Manual or Auto mode.
Pulse Oximetry Measurement 9-10 SpO2 Monitoring Understanding SpO2 Alarms SpO2 monitoring offers high and low limit alarms, and a high priority (red level) oxygen desaturation alarm. For adult patients, the SpO2 low limit can be set between 50 and 99% inclusive, in 1% increments. For pediatric patients, the SpO2 low limit can be set between 30 and 99% inclusive, in 1% increments. You cannot set the low limit below the desaturation limit. The SpO2 high alarm limit can be set between 51 and 100% inclusive, in 1% increments for adult patients and set for pediatric patients between 31 and 100% inclusive, in 1% increments. The delay between the physiologic alarm condition and alarm annunciation at the MX40 is <16 seconds. This means that the MX40 will generate an alarm if the averaged numeric value on the display exists beyond the alarm limit for more than a maximum of 16 seconds. Setting the high SpO2 alarm limit to 100% is equivalent to switching off the high alarm. Therefore the upper alarm limit for oxygen saturation must be carefully selected in accordance with accepted clinical practices. The default setting for SpO2 yellow alarms is latched. That is, when an SpO2 limit is exceeded, you will need to acknowledge it at the Information Center. The sound will be silenced but the message will remain on the display until the condition is resolved.
Monitoring with other Assigned Devices 10-1 10. Monitoring with other Assigned Devices This section provides information about the use of the MX40 when it is assigned to other monitoring devices. The MX40 can be assigned to IntelliVue Patient Monitors or IntelliVue Cableless Measurements for SpO2 and NBP. The connection to these other devices is done by pairing networked devices or using the integrated short-range radio of the MX40. For additional information on IntelliVue Patient Monitor or IntelliVue Cableless Measurements operation, consult the Instructions for Use that accompanied the device. Warning Assignment of the MX40 to IntelliVue Patient Monitors is only supported when the patient monitor (MP5,MP5T,MP5SC, MP2 or X2 only) is equipped with a short-range radio. Monitors that have this equipment will display the short-range radio symbol on the label. Caution When the MX40 is connected to a patient monitor using the MX40 / IntelliVue Patient Monitor Adapter Cable, (p/n 989803172211), the SpO2 sensor must be directly connected to the patient monitor to monitor SpO2. Note — Assignment of the MX40 to IntelliVue Patient Monitors is not available with patient monitors connected to the M3140 Information Center. Note — The MP5T and MP5SC are non-networked devices as they does not support a connection to the Information Center.

Monitoring with the MX40 at the Information Center 11-1 11. Monitoring with the MX40 at the Information Center This section describes the behavior of the MX40 as it relates to what is displayed at the Information Center. What is displayed depends on which version of the Information Center is in use, IntelliVue Information Center Release N or earlier (referred to here as IIC), or IntelliVue Information Center iX (referred here to as IIC iX). MX40 Connection to the Information Center ...................................... 11-2 MX40 Controls in the Patient Window (IIC) ....................................... 11-3 MX40 Controls in the Patient Window (IIC iX) .................................. 11-5 Locating the MX40 (Find Device) .......................................................... 11-7 Viewing Device Location and Location History (optional) ............... 11-8 Using the Device Location Client (optional - IIC only) ...................... 11-9 Patient Configurable Settings in Telemetry Setup (IIC)................... 11-10 Unit Configurable Settings (IIC).......................................................... 11-13 Global Settings (IIC iX) ......................................................................... 11-21
MX40 Connection to the Information Center 11-2 Monitoring with the MX40 at the Information Center MX40 Connection to the Information Center Once the MX40 has been assigned to a sector at the Information Center, the settings (alarms, arrhythmia and configured Unit settings) are synchronized with the MX40. You may see a "Settings sync'd" message in the Status Area on connection, re-connection, and anytime the settings are updated at the Information Center. Arrhythmia Learning/Relearn occurs on connection and re-connection to the IIC. Warning Since Relearn happens automatically at the IIC, if learning takes place during ventricular rhythm, the ectopics can be incorrectly learned as the normal QRS complex. This can result in missed detection of subsequent events of V-Tach and V-Fib. For this reason, you should: 1 Respond promptly to any technical alarm. 2 Ensure that the arrhythmia algorithm is labeling beats correctly. Upon loss of connection to the Information Center the MX40:  turns on its display  displays the "NO CENTRAL MONIT" INOP  uses the last known settings from the Information Center.  new physiological alarms are announced locally only.  Active alarms that occurred prior to the loss of connection can be viewed in the Alarm List. When a loss of battery power occurs while not connected to the Information Center, the MX40 retains the last known alarm limits and vitals trends data but this is not sent to the Information Center at re-connection. Patient name is restored at re-connection. When operating wirelessly via a short-range radio connection to an IntelliVue Patient Monitor, changes made to patient name are updated at the Information Center and the patient monitor, however, they are not reflected in the Patient Information Area on the MX40. The update occurs when network connection is restored.

Charging Lithium-ion Rechargeable Batteries 14-8 Maintenance Charging Lithium-ion Rechargeable Batteries The li-ion rechargeable battery is recharged using the IntelliVue CL Charging Station. To charge a battery, place it onto a charger slot on the charging station. The battery power indicators will supply information about the charge status. Warning  Always use the supplied power cord with the grounded mains plug to connect the charging station to a grounded AC mains socket. Never adapt the mains plug from the power supply to fit an ungrounded AC mains socket.  Do not use AC mains extension cords or multiple socket outlets. If a multiple portable socket outlet without an approved isolation transformer is used, the interruption of its protective grounding may result in leakage currents equal to the sum of the individual ground leakage currents, so exceeding allowable limits.  Do not connect any devices that are not supported as part of the system. Battery Power Indicators There are various indications which help you keep track of the battery power status.  LEDs on the charging station slots  battery status information on both the MX40 and the charging station's display  INOP messages The indicators always show the remaining capacity in relation to the battery's actual maximum capacity which may lessen as the battery ages. Charging Station LEDs The nine charger slot LEDs show the battery status of the device in their slot and are switched off if no battery is inserted. If a battery is put on a charging station slot, the corresponding LED will flash yellow until the battery's current state has been identified. Then a beep is issued and the LED reflects the battery status as described in the table below.
Charging Lithium-ion Rechargeable Batteries Maintenance 14-9 Status LED no battery on charger slot off battery put on charger slot flashing yellow battery not properly recognized, error cyan battery recognized, battery charging yellow battery recognized, battery full (>90%) green The AC Power / Error LED is  green when the charging station is connected to AC power  cyan during startup or to indicate a general charging station error Note — Wiping of battery contacts with an alcohol solution after cleaning is recommended. Battery Status on the Charging Station Display The IntelliVue CL Charging Station display provides a quick overview of all the connected devices and their battery status. The screen is arranged in the same layout as the charger slots. Battery Lifetime Management The lifetime of a li-ion battery depends on the frequency and duration of use. When properly cared for, the useful life is approximately 4 years or 500 complete charge-discharge cycles, whichever comes first. In addition, experience indicates that the incidence of failure may increase with battery service life due to the accumulated stresses of daily use. We therefore strongly recommend that li-ion batteries be replaced after 2 years or 500 complete charge-discharge cycles. The age of a li-ion battery begins at the date of manufacture. The date of manufacture is listed on the side of the battery.
Charging Lithium-ion Rechargeable Batteries 14-10 Maintenance Battery Disposal Discharge the battery and insulate the terminals with tape before disposal. Dispose of used batteries promptly and in accordance with local recycling regulations.

Not intended for home use. Intended for use by health care professionals. Indications for Use Indicated for use by health care professionals whenever there is a need for monitoring the physiological parameters of patients. Intended for monitoring and recording of, and to generate alarms for, multiple physiological parameters of adults and pediatrics in hospital environments and during transport inside hospitals. Intended Uses of MX40 The MX40 is to be used primarily as a traditional telemetry medical device. It connects to the IntelliVue Information Center by way of a wireless network. When the MX40 is connected the IntelliVue Information Center the IntelliVue Information Center provides the primary patient monitoring and alarming function. The MX40 does not automatically provide local monitoring or alarming when connected to the Information Center.
Regulatory Information 15-4 Safety Standards & Specifications The MX40 can provide time-limited local monitoring when it is not connected to the wireless network. Unlike a traditional bedside monitor which operates on AC power, the MX40 is powered by battery and cannot provide continuous monitoring. Authorized EU Representative Philips Medizin Systeme Deutschland Hewlett-Packard-Strasse 2 D 71034, Boeblingen Germany Patient Population This device is not for use with infant or neonatal patients. Clinical judgment must be used to determine when the MX40 should be used on a specific pediatric patient, as it is not possible to assign a precise weight or age to ECG performance. Use of the device is restricted to one patient at a time. The components/accessories which come into contact with the patient’s skin are in compliance with the relevant requirements of EN ISO 10993-1 for Biocompatibility. The device is not designed for direct contact with the patient’s skin. The accompanying pouch is the appropriate means for holding the device. Rx Federal Law restricts this device to sale by or on the order of a physician. Essential Performance The IntelliVue MX40 provides Essential Performance (EP) under normal operating conditions (includes EMC exposure) only as a complete Medical Electrical System, consisting of the MX40, MPx companion monitor (Optional), IntelliVue CL SpO2 and NBP Cableless Measurement devices(Optional), IntelliVue Telemetry Network Infrastructure, and the Information Center.
Regulatory Information Safety Standards & Specifications 15-5 The System achieves its Essential Performance exclusively through alarm generation at the IntelliVue Information Center and locally at the MX40, based on configuration. The IntelliVue MX40 protects the patient from unacceptable immediate clinical risk by generating specific Physiological Alarms when appropriate. If the system cannot generate Physiological Alarms, then relevant Severe or Hard-Level Technical Alarms (Inops) are created. Risk Management Considerations Warning The MX40 operates exclusively via a wireless network connection, therefore, it should not be used for primary monitoring in applications where momentary loss of the ECG is unacceptable at the Information Center. It sends ECG and optionally pulse oximetry data to the Information Center, where the Information Center displays real-time patient data, provides alarm annunciation, data storage and review applications. The ECG waveform data, alarms and optionally SpO2 can always be viewed on the MX40 regardless of the connection to the Information Center. Smart Hopping technology alleviates most of the problems associated with legacy telemetry technologies. Reception problems are less frequent, because Smart Hopping avoids interference and moves to a different access point if the signal strength is too low. The level of radio frequency activity is always fluctuating in the environment. If the level becomes high enough to significantly interfere with transceiver operation, the system responds by moving to another "cleaner" area where there is less activity. Dropouts Because the MX40 operates exclusively via a wireless network connection, under certain frequency conditions dropouts can occur. Dropouts result from a weak signal or RF interference, and appear on the waveform when the signal "drops" to the bottom of the channel for a minimum of 200 ms. If dropouts are frequent enough to affect the heart rate count, the "Cannot Analyze ECG" or "Cannot Analyze ST" technical alarm occurs. If there are enough dropouts to cause disassociation/reassociation with the Information Center, events in the Clinical Review application can reflect loss of data for up to 1 minute in the worst case.
Regulatory Information 15-6 Safety Standards & Specifications Problem Cause Remedy Dropouts Low signal strength RF interference See "Signal Strength" below. See "Radio Frequency Interference" below. Monitoring Considerations  Patient should be restricted to the designated coverage area. Monitoring performance will degrade if patients go outside the radius of coverage of the receiving wireless network.  A patient location strategy is critical to a telemetry system. If a life-threatening event occurs, the clinician must be able to locate the patient quickly. The importance of this increases as the coverage area increases.  Frequency management is the responsibility of the hospital. Philips Healthcare has no control over the RF environment in the hospital. If interference exists at the operating frequencies of the telemetry equipment, telemetry performance will be affected. Careful selection of frequencies for all wireless devices used within a facility (transceivers, other wireless medical devices, etc.) is important to prevent interference between them. Caution IEC/ANSI/AAMI 80001-1:2010 Philips recognizes the importance of a safe and effective network that meets both the business needs of a healthcare facility, IT networking requirements, and the clinical functionality. Philips supports the IEC 80001-1 standard in regards to working as a partner with a healthcare organization in the design, implementation, and management of the Medical IT-Network to properly provision and support not only Philips devices, but all the devices using the network. Applying the principles of risk management to hospital frameworks is highly encouraged.
Regulatory Information Safety Standards & Specifications 15-7 When operating the MX40 on a Customer Supplied Clinical Network, Philips strongly encourages our customers to perform risk management of their Medical IT-Network infrastructure in accordance with IEC 80001. If the MX40 experiences loss of network connectivity, technical alerts at the Information Center ("No Signal") and at the MX40 ("No Central Monitor") will occur. The MX40 will also automatically revert to local monitor mode which activates display of patient data on the MX40 – however, when in this state, battery life will be shortened.
Electromagnetic Compatibility 15-8 Safety Standards & Specifications Electromagnetic Compatibility Medical electrical equipment can either generate or receive electromagnetic interference. This product has been evaluated for electromagnetic compatibility (EMC) with the appropriate accessories according to IEC 60601-1-2:2001, the international standard for EMC for medical electrical equipment. This IEC standard has been adopted in the European Union as the European Norm, EN 60601-1-2:2001. Radio frequency (RF) interference from nearby transmitting devices can degrade performance of the product. Electromagnetic compatibility with surrounding devices should be assessed prior to using the product. Fixed, portable, and mobile radio frequency communications equipment can also affect the performance of medical equipment. See your service provider for assistance with the minimum recommended separation distance between RF communications equipment and the product. The cables, sensors/transducers, and other accessories for which compliance is claimed are listed in the Service and User documentation accompanying the product. Warnings  The use of accessories, transducers and cables other than those specified in the product service and user documentation can result in increased electromagnetic emissions or decreased immunity of the product.  Short-range radio connections are subject to interruption due to interference from other radio sources in the vicinity, including microwaves, bluetooth devices, and DECT phones. Outside the frequency band and 5% above and below, i.e. the exclusion band according to IEC 60601-1-2, the short-range radio connection is immune up to 3V/m in the frequency range from 80MHz to 2.5 GHz. Depending on the strength and duration of the interference, the interruption may occur for an extended period. Any interruption of the signal due to interference, moving out of range, or for other reasons is indicated with a Tele Disconnected INOP message.  The product should not be used next to or stacked with other equipment. If you must stack the product, you must check that normal operation is possible in the necessary configuration before the product is used on patients.
Electromagnetic Compatibility Safety Standards & Specifications 15-9 Reducing Electromagnetic Interference The MX40 and associated accessories can be susceptible to interference from other RF energy sources and continuous, repetitive, power line bursts. Examples of other sources of RF interference are other medical electrical devices, cellular products, information technology equipment, and radio/television transmission. If interference is encountered, as demonstrated by artifact on the ECG or dramatic variations in physiological parameter measurement values, attempt to locate the source. Assess the following:  Is the interference due to misplaced or poorly applied electrodes or sensors? If so, re-apply electrodes and sensors correctly according to directions in Chapter 6.  Is the interference intermittent or constant?  Does the interference occur only in certain locations?  Does the interference occur only when in close proximity to certain medical electrical equipment? Once the source is located, attempt to attenuate the interference by distancing the MX40 from the source as much as possible. If assistance is needed, contact your local service representative. Restrictions for Use Artifact on ECG and other physiological waveforms caused by electromagnetic interference should be evaluated by a physician or physician authorized personnel to determine if it will negatively impact patient diagnosis or treatment. Electromagnetic Compatibility (EMC) Specifications Take special precautions regarding electromagnetic compatibility (EMC) when using medical electrical equipment. You must operate your monitoring equipment according to the EMC information provided in this book. Portable and mobile radiofrequency (RF) communications equipment can affect medical electrical equipment. Accessories Compliant with EMC Standards All accessories listed in the accessories section comply, in combination with the MX40, with the requirements of IEC 60601-1-2:2001 + A1:2004.

Electromagnetic Compatibility Safety Standards & Specifications 15-11 Recommended Separation Distance Warning The MX40, equipped with a wireless network interface, intentionally receives RF electromagnetic energy for the purpose of its operation. Therefore, other equipment may cause interference, even if that other equipment complies with CISPR emission requirements. In the following table, P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m). Portable and mobile RF communications equipment should be used no closer to any part of the MX40, including cables, than the recommended separation distance calculated from the equation appropriate for the frequency of the transmitter. Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be less than the compliance level in each frequency range. Interference may occur in the vicinity of equipment marked with this symbol: Immunity Test IEC 60601-1-2 Test Level Compliance Level Electromagnetic Environment Guidance Conducted RF IEC 61000-4-6 3 Vrms 150 kHz to 80 MHz 3 VRMS Recommended separation distance: d = 1.2√P Radiated RF IEC 61000-4-3 3 V/m 80 MHz to 2.5 GHz 3 V/m Recommended separation distance: 80 MHz to 800 MHz d = 1.2√P 800 MHz to 2.5 GHz d = 2.3√P
Electromagnetic Compatibility 15-12 Safety Standards & Specifications Field strengths from fixed transmitters, such as base stations for radio (cellular, cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the monitor is used exceeds the applicable RF compliance level above, the MX40 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the monitor. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people. The MX40 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or user of the monitor can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment and the monitor as recommended below, according to the maximum output power of the communications equipment.
