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

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.

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

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

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
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

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 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

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.

Technical Alarms (INOPs)
Technical Alarms, or INOPs (inoperative conditions), are sourced at the
MX40, the ST/AR algorithm running at the Information Center, or the
IntelliVue Patient Monitor. They identify inoperative conditions (that is
conditions where the system is not operating properly and therefore cannot
measure or detect alarm conditions reliably). There are four levels of
Technical Alarms:
Severe - Monitoring and alarm generation are disabled. Visual alarm
indicator on the MX40. Audible tone at the Information Center. Must be
acknowledged by a clinician.
Hard - Monitoring and alarm generation are disabled. Visual alarm
indicator on the MX40. Audible tone at the Information Center.
If the hard INOP is "latched", the sound will be silenced, but the
message will remain on the display until resolution of the offending
condition.
Soft - Monitoring and alarms remain active. Visual alarm indicator on
the MX40 and at the Information Center. No audible tones are
generated at the Information Center
Red/Yellow - Replace Battery and ECG Leads Off INOPs may be
configured to display as either Red or Yellow Technical Alarms.
Note - The ECG Leads Off INOP will initially display as a cyan
technical alarm until a valid ECG signal is obtained.

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.

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

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

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.

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.

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.

Note — When operating with the IntelliVue Information Center Release N
or earlier, the ST/AR Arrhythmia Algorithm operates and generates alarms
independently at both the MX40 and the Information Center. 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.

Learning
The arrhythmia system’s goal is to learn the patient’s normal complexes so
it can differentiate abnormal beats. 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.

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.

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.

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.

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
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
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.

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.

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.

short-range radio, its display is primarily inactive. There is no viewable
patient data on the display, however, battery status information is available
if the display is turned on.

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).

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.

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.

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

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.

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.

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.
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).

SpO2 Numerics -
Averaging
5 - 20 seconds (default = 10 seconds)
Note—The update rate for the SpO2 pulse oximetry value and pulse rate is
typically 1 second. This can be extended to a max. 60 s when NBP is
measured on the same limb, with a corresponding INOP message after a
max. of 30 s, indicating that the displayed values are not current values.
The effect of SpO2 pulse oximetry on data averaging is internally controllable
by the patient worn monitorMX40, with no user controls.
SpO2 & Pulse Numerics -
Update Rate
Transmitted once per second.
Note—The update rate for the SpO2 pulse oximetry value and pulse rate is
typically 1 second. This can be extended to a max. 60 s when NBP is
measured on the same limb, with a corresponding INOP message after a
max. of 30 s, indicating that the displayed values are not current values.
Pleth Wave- Sampling

Technical Alarms
(INOPs)
Triggered if the sensor is disconnected, if a pulse is not detected, if the signal
is noisy, if light interference is detected, if the sensor is defective, if the
measurement is erratic, or if the module is malfunctioning
Wavelength Range
500 to 1000 nm
Note—Information about wavelength range can be especially useful to
clinicians (e.g., clinicians performing photodynamic therapy).
