Product Safety Information vWarningWarningDo 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.WarningWarningThis device is not to be used in the vicinity of electrosurgical units because use may interrupt or interfere with the transmission of signals from the transceiver.WarningWarningThis equipment is not suitable for use in the presence of a flammable anesthetic mixture with air or with oxygen or nitrous oxideWarningWarningDo not use patient cables with detachable lead wires that have exposed male pins. Electrocution could result if these pins are plugged into AC power.WarningWarningUse of product accessories (e.g., ECG leadsets, SpO2 sensors) other than those prescribed by Philips could lead to patient injury.WarningWarningTo avoid strangulation, do not tie a pouch solely around the patient’s neck.
Product Safety InformationviECG/ Arrhythmia -All Patients WarningWarningECG SAFETY FOR ALL PATIENTSAlways confirm Information Center observations with clinical observation of the patient before administering interventions.Every lead must be secured to an electrode on the patient. Conductive parts of electrodes must not contact earth or other conductive parts.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.When switching between EASI and standard monitoring, there is a loss of data for 30 seconds.
Product Safety Information viiWarningWarningST/AR ARRHYTHMIA SAFETY FOR ALL PATIENTSDuring 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.Learning/Relearning- If you initiate learning 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.- When using EASI ECG monitoring, Relearn happens automatically when there is a LEADS OFF technical alarm. 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. Be sure to check the beat labels and initiate a relearn to correct. Therefore, when a technical alarm is generated:1. Respond to the technical alarm [for example, reconnect the electrode(s)].2. Ensure that the arrhythmia algorithm is labeling beats correctly.
Product Safety InformationviiiECG/Arrhythmia - Paced Patients WarningWarningECG SAFETY FOR PACED PATIENTSThe output power of the transceiver 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 transceiver 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 Philips IntelliVue Telemetry System. See the IntelliVue Information Center Instructions for Use for additional information on monitoring paced patients.
Product Safety Information ixWarningWarningST/AR ARRHYTHMIA SAFETY FOR PACED PATIENTSIt is possible that pacemaker pulses will not be detected when the ECG analog output of a defibrillator or telemetry unit is plugged into a bedside monitor. This can result in the arrhythmia algorithm’s failure to detect pacemaker non-capture or asystole.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. Keep pacemaker patients under close observation.-- 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.-- When arrhythmia monitoring 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.For patients who exhibit intrinsic rhythm only, 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 alarms you when the patient begins pacing. Proper detection and classification of the paced rhythm can then be determined.-- 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 can result in the arrhythmia algorithm’s failure to detect pacemaker non-capture or asystole.
Product Safety InformationxSpO2WarningWarningSpO2 SAFETYAlways confirm Information Center 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.Using a sensor during MR imaging can cause severe burns. To minimize this risk, ensure that the cable is positioned so that no inductive loops are formed. If the sensor does not appear to be operating properly, remove it immediately from the patient.Do not use disposable sensors on patients who exhibit allergic reactions to the adhesive.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.

The Philips IntelliVue Telemetry System1-2 Basic Operation The Philips IntelliVue Telemetry SystemThe Philips IntelliVue Telemetry System with Smart-hopping Technology provides ambulatory and bedside monitoring of ECG and SpO2 parameters over the radio frequency (RF) spectrum newly allocated for medical telemetry applications by the Federal Communications Commission (FCC). The System enables clinically significant data and control information for adult and pediatric patients in healthcare facilities to be received from and sent to the transceiver, a patient-worn device, via a bi-directional RF link over the Wireless Medical Telemetry Service (WMTS) spectrums 1395-1400 MHz and 1427-1432 MHz.The System uses smart-hopping technology to dynamically manage the RF spectrum utilization per transceiver, thus allowing a virtually unlimited number of simultaneously operating transceivers within the Philips IntelliVue Telemetry System. The frequency-agile system changes frequency without user involvement or awareness whenever interference occurs.The System encompasses a number of individual units which connect together to form a complete method of transporting ambulatory patient data to a central repository for subsequent distribution to clinical staff. An installation typically consists of the following components:• M4841A Transceivers, bi-directional patient-worn devices• M4842A Access Points (AP), centers for bidirectional communication between the transceivers and the Information Center.• IntelliVue Wireless Network (IWN) infrastructure (including M4843A Access Point Controllers, M4844A Sync Units, M4845A Power Supply Units)• M3150A IntelliVue Information Center for centralized monitoring• M3154A IntelliVue Database Server (optional) for centralized data management• M2636A TeleMon A02/A03 Companion Monitor (optional) for local display, NBP measurement and local alarms.The network interconnects Access Points to the Information Center and other central equipment via the same network that connects IntelliVue bedsides to the Information Center. Access points receive signals, and unlike traditional antenna systems, can communicate bidirectionally. Access Points are powered, controlled and managed remotely via the IWN.
The IntelliVue Transceiver Basic Operation 1-3System Features • Full patient mobility within the areas defined by the wireless coverage provided by multiple Access Points.• Expanded geographic coverage area for a a given patient assigned to an IntelliVue Clinical Network. Physiological data is transported from the transceiver; a reverse data channel enables data to be transported to the transceiver.• 3-minute Alarm Pause/Suspend initiated at the transceiver.• Standby mode when a patient is away from the unit and not being monitored by the Philips IntelliVue Telemetry System.• Find Device feature for locating a lost transceiver within the coverage area. • Access Points operating concurrently with the networked bedside wireless capability while sharing some of the ICN infrastructure. • Use of the radio spectrums newly allocated by the FCC specifically for medical telemetry applications.• Connectivity to TeleMon for display of patient measurements - including NBP - at the bedside. The IntelliVue TransceiverThe Philips IntelliVue transceiver is a patient-worm device for monitoring ECG and SpO2 on adult and pediatric patients in the IntelliVue Telemetry System System Information Flow/Smart-hopping diagram to come
The IntelliVue Transceiver1-4 Basic Operation with Smart-Hopping Technology, a cellular infrastructure network. The transceiver combines traditional transmitter features with two-way communication capability with the IntelliVue Information Center. The transceiver is designed to be easy for clinicians to use and comfortable for patients to wear. Colored labels provide departmental identifiers. The leadsets are optimized for ambulating patients, with a cable length of 79 cm (30 inches). Protective covers prevent dirt from accessing unused ECG and SpO2 cable ports, thus simplifying cleaning. The transceiver is available in two models, the ECG only called the IntelliVue TRx, and the ECG-SPO2 version, called the IntelliVue TRx+. The models are listed below and illustrated on the following pages in this chapter. Subsequent tables describe the buttons, indicators, labels, ports, safety symbols & other markings, and auditory information signals of the transceiver respectively.The transceiver comes with a start-up kit of batteries, electrodes, and pouches.Transceiver Model(M4841A) MeasurementsIntelliVue TRx ECGIntelliVue TRx+ ECG, SpO2

Turning the Transceiver On Basic Operation 1-15TransceiverSafetyInformation WarningWarningIf another radio medical device is operating at the same frequency as an IntelliVue Transceiver, it is possible that either device will not function properly. WarningWarningAlthough the transceiver is shielded against Electromagnetic Interference (EMI), avoid the use of other electrically radiating devices in close proximity to the transceiver because they might interfere with transceiver operation.WarningWarningPlace the transceiver in a pouch or over clothing, or both, during patient use. The transceiver should not touch the patient’s skin during use.Turning the Transceiver OnWarningWarningArrhythmia relearning is initiated whenever the transceiver is powered down for one minute or longer. Be sure to check your patient’s arrhythmia annotation for accuracy whenever relearn has occurred.The transceiver is powered by two AA alkaline batteries. To turn the transceiver on, insert both batteries. Remove the batteries to turn the power off.The configuration data set by the Service Provider prior to transceiver use is retained after battery removal.
Turning the Transceiver On1-16 Basic Operation When the transceiver is turned on, all indicators illuminate briefly and a sequence of sounds indicates the instrument is ready for use. You should hear a single beep indicating that the self test was passed, followed by a series of double beeps while the transceiver attempts to associate with the Information Center. The cessation of sounds indicates a successful association. If you hear a single double beep or any other sound sequence, the automatic self-test of the device has not passed, or there is another problem. Contact your Service Provider. Turning the Transceiver OffTurn off the transceiver by removing the batteries. A NO SIGNAL technical alarm will be in effect at the Information Center until the device is turned on or until Standby is initiated.Telemetry monitoring can be turned off in the following ways:• Manually, by activating Monitoring Standby at the Information Center (see “Standby Mode” on page 2-5).• Automatically, if Transceiver RF Auto Shutoff is enabled and there is no ECG signal for 10 minutes.Note—Turning off telemetry monitoring does not turn off the transceiver.Auto Shutoff Automatic Shutoff causes the transceiver to stop broadcasting a radio signal if there is no ECG signal for 10 minutes. This prevents interference with other transceivers in use. The technical alarm text at the Information Center is Transmitter Off. To conserve battery power, remove batteries. Sounds at successful start-up insert batteriesSelf-test Transceiver looking for Info Center beep beep repeated every 3 seconds1 beep (pass)Connectedno beep
Testing intelliVue Transceiver Functionality Basic Operation 1-17To restart monitoring, insert batteries if necessary, attach leads to the patient and press the Check button to verify association with the Information Center.Testing intelliVue Transceiver FunctionalityThere are two tests of IntelliVue Transceiver functionality:•Self Test -performed automatically each time the transceiver is turned on•Status Check - initiated manually by the clinician.Self TestWarningWarningDo not use the transceiver for patient monitoring if it fails the Power On Self Test.A self test of the transceiver functions is automatically performed each time that the transceiver is turned on (that is, batteries are inserted). In Case ofFailure If any portion of the self test fails, the transceiver will attempt to report the failure to the monitoring system. In case of failure, use another transceiver, and contact your Service Provider.Self Test StatusAuditory Signal (if configured on) Visual IndicatorsPassed Single beep All indicators illuminate for 3 secondsFailed Double beep One or more indicators do not light up.
Testing intelliVue Transceiver Functionality1-18 Basic Operation Status Check You can check the status of the transceiver indicators at any time.To initiate a Status Check, use the following instructions.Step Action1Press the Check button.The following indicators should illuminate for as long as the Check button is depressed.• Battery gauge• Type of leadset• EASI (if in use)2 If one or more of the expected indicators do not light up, check the following:• Lead block insertion. Make sure the leadset is correctly inserted in the transceiver and the orange line at the base of the cable is not visible (see “Connecting the ECG Cable” on page 3-19).• Power and position of batteries (see “Checking the Battery Power Level” on page 1-22)• Lead positions and connections (see “Verifying Electrode Connections” on page 3-22)If there is still a problem, contact your Service Provider for assistance.
Battery Information Basic Operation 1-19Battery InformationBattery Safety Information WarningWarningUse Duracell MN 1500 AA 1.5V Alkaline batteries to ensure specified performance. Outdated, mismatched or poor-quality batteries can give unacceptable performance (e.g., insufficient Battery-Low warning time). The use of fresh high-quality alkaline batteries is strongly recommended.Batteries should be removed from the transceiver 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 instructions in “Chapter 7. Maintenance & Troubleshooting”. Wash hands.Certain failure conditions, such as short circuits, can cause a battery to overheat during normal use. High temperatures can cause burns to the patient and/or user. If the transceiver becomes hot to the touch, place it aside until it cools. Then remove the batteries and discard them. Have the transceiver operation checked by your Service Provider to identify the cause of overheating.The battery door must be closed during defibrillation.If you receive a BATTERY LOW alarm, the batteries must be promptly replaced. A "Battery Low" condition that is not corrected will result in a transceiver shutdown and cessation of monitoring.
Battery Information1-20 Basic Operation Disposal ofBatteries CautionThe batteries must be removed if a transceiver will be stored for an extended period of time.Important—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 Life Battery life is dependent upon:• Condition of the batteries• Parameters being monitored - ECG only, ECG and Spot Check SpO2, or ECG and Continuous SpO2.By observing the following guidelines, you can optimize battery life in the transceiver: • REMOVE the batteries when the transceiver is not in use. • Disconnect the SpO2 extender cable (if used). (When the SpO2 sensor is disconnected, the SpO2 functionality is automatically powered down, but an extender cable will continue to drain power from the SpO2 electronics.)Inserting/Removing Batteries WarningWarningArrhythmia relearning is initiated whenever the transceiver is powered down for one minute or longer. Be sure to check your patient’s arrhythmia annotation for accuracy whenever relearn has occurred.CautionRemove the batteries before storing a transceiver for an extended period of time.
Battery Information Basic Operation 1-21The battery compartment is located at the bottom of the transceiver behind a swinging door. It accommodates a pair of AA 1.5V Alkaline batteries. Only this type of disposable battery shall be used.Important—Do not use rechargeable batteries. Use of this type of battery will adversely affect:• Battery gauge performance• Battery low warnings• Battery life performanceInsert batteries into the transceiver using the following procedure.Step Action1 Open the battery compartment by swinging the compartment door 90o counterclockwise into an open hinged position.2 Insert two AA 1.5V Alkaline batteries, matching the polarity with the +/- indications inside the compartment.Note— Both batteries are inserted with the + polarity in the same direction.++
Battery Information1-22 Basic Operation Removing theBatteries Batteries should be changed in sets, that is, if you change one battery, change them both. To remove the batteries, simply open the battery compartment door and push from the opening at the back of the compartment to pop the batteries out. Transceiver settings (ECG leadset type, SpO2 mode, volume, etc.) are retained indefinitely when the batteries are removed.If you remove good batteries to turn off the transceiver, keep them together as a set for later re-use so that both batteries will have the same level of power remaining.Batteries should be removed when the transceiver is not in use or is being stored. DO NOT "STORE" BATTERIES BY LEAVING THEM IN THE INCORRECT POLARITY POSITION IN THE TRANSCEIVER. Be careful not to short circuit the batteries. Short circuits are caused when a piece of metal touches both the positive and negative terminals simultaneously (for example, by carrying batteries in a pocket with loose change). More than a momentary short circuit will generally reduce the battery life. In case of a short circuit, discard both batteries in a pair, or just the shorted one if the batteries are new.Checking the Battery Power LevelWhen the Check button is pressed, the battery gauge on the transceiver indicates the battery power level. It is reliable only when specified batteries (i.e., AA 1.5V Alkaline) are used. The battery gauge is also displayed in the Patient Sector at the Information Center to enable you to closely monitor battery status, for example, at change of shift.3 Close the battery compartment door.4 Listen for the start-up sounds.Watch for the indicators on the front of the transceiver to illuminate briefly.5 Connect/reconnect the patient cables to the transceiver.Step Action

Check that the batteries are inserted properly.2. Replace both batteries. 3. If there are still no indicators on the battery gauge, contact your Service Provider.If the indicators illuminate but do not behave as described above, the transceiver has malfunctioned. Contact your Service Provider.
Briefing the Patient1-24 Basic Operation Briefing the PatientWarningWarningPatients should be instructed not to open the battery cover while the transceiver is in use.If the Telemetry button has been configured to generate a Nurse Call, remote recording, or both, instruct the patient to use the button when needed.Note—If desired, you can turn off patient use of the button at the Information Center. See “Patient-Configurable Settings in Telemetry Setup” on page 6-3.Pouch Use The transceiver is not designed for direct contact with the patient’s skin. During normal use, the transceiver should be worn over clothing, in a pocket or, preferably, in a pouch. The carrying pouch is an appropriate means for holding the transceiver.
Briefing the Patient Basic Operation 1-25Securing the Pouch Step Action1 Secure the pouch on the patient with upper ties around the patient’s head and arm, and lower ties around the patient’s lower torso.WarningWarningTo avoid strangulation, do not tie a pouch solely around the patient’s neck.2 Insert the transceiver into the pouch with lead wires and SpO2 sensor cable, if used, exiting from the same side. Important—Do not coil the cables inside the pouch. They are part of the wireless system, and need to be freely exposed.
Briefing the Patient1-26 Basic Operation ShoweringWarningWarningSignal quality and leads off detection may be compromised when showering due to significant patient movement. Appropriate clinical precautions must be taken.The transceiver can be used to monitor a patient in the shower, but only when placed inside a Philips carrying pouch with the flap closed and the snaps secured. The combination of the transceiver and pouch will withstand showering for up to 10 minutes.3 Fold the flap down and snap closed. 4 Check that the patient is comfortable wearing the pouch with transceiver.Step Action
Transceiver Use with TeleMon A02/A03 Basic Operation 1-27Drying theTransceiverafterShoweringAfter showering, perform the following steps to continue monitoring:1. Pat dry the leadset connections at the electrodes.2. Wipe the lead wires with care.3. If wet, dry the outside of the transceiver with a non-lint producing cloth.4. If wet, wipe the inside of the battery compartment dry. Dry the batteries.5. If wet, disconnect the ECG lead block and shake out any water. Dry the connector pin area with a cotton swab.Note—The transceiver should not be used for monitoring if the battery compartment is wet. Remove the batteries and wipe the compartment dry before continued monitoring use.AccidentalWetting If the transceiver is accidentally immersed in liquid for up to 5 minutes, no damage to the device and no electrical safety issues for the patient will result. Remove the device, dry it off, and follow the procedure for cleaning/disinfection or cleaning/cross-infection prevention under “Troubleshooting” on page 7-15 as appropriate.Transceiver Use with TeleMon A02/A03When tethered to TeleMon, the following transceiver operational behavior will be in effect.Alarms• 3 minute alarm pause/suspend can be initiated only from TeleMon, not from the transceiver or from the Information Center. The Alarm Suspend/Pause indicator on the transceiver will accurately reflect the current state of alarm pause.• Standby mode is not available.ECG Operation• Vb, the second V-lead in 6-wire lead-set, is not supported.• After a change in leadset, the TeleMon returns to the default ECG settings, and arrhythmia relearn occurs automatically. Be sure to check the monitoring leads after you switch leads.SpO2 Operation
Transceiver Use with TeleMon A02/A031-28 Basic Operation •SpO2 is always in continuous mode.• Changes in SpO2 mode do not take effect until after the transceiver is disconnected from TeleMon. Mode settings are defined in the following table:• After a change in SpO2 sensor, TeleMon returns to the default ECG settings, and arrhythmia relearn occurs automatically. Be sure to check the monitoring leads after you change the sensor.Transceiver Operational Controls & Indicators• When you press the Telemetry button, a Nurse Call alarm, recording, alarm and recording, or neither will be generated, depending on the configuration at the Information Center.• When you press the Check button, the transceiver battery gauge indicates full power, regardless of actual battery strength.• When you press the Telemetry and Check buttons together, there is no action; a 3-minute alarm pause/suspend can be initiated only from TeleMon. The alarm pause indicator on the transceiver will accurately reflect the current state of alarm pause.• When the transceiver is connected to TeleMon, the battery gauge on the transceiver and displayed at the Information Center always indicates "full" regardless of actual battery power. To update the gauge, disconnect the transceiver and wait several seconds for the updated battery strength to be displayed.Defibrillation• In the event of patient defibrillation, it may take several seconds for the ECG trace to reappear on the screen.Mode at TeleMon Mode at Disconnected TransceiverContinuous Continuous5-min.

Alarm Indicators2-2 Alarms Alarm IndicatorsA description of visual and auditory information signals for patient and technical alarms on the Information Center is located in the IntelliVue Information Center Instructions for Use and the Information Center Online Help.The Information Center documentation also includes the default alarm settings and physiological alarm limit ranges Testing Alarm IndicatorsThe visual alarm information signal on the transceiver is the Alarms Suspend icon. During self test, the Alarm Suspend indicator illuminates, and a single tone indicates association with the Information Center. These positive test results indicate that the Alarm Suspend icon on the transceiver is functioning correctly (see “Status Check” on page 1-18).Suspending/Pausing AlarmsWarningWarningIf the Alarms Suspend indicator on the transceiver remains illuminated after the button combination to unsuspend alarms is pressed, a the transceiver malfunction may have occurred. Alarms resume automatically after the 3 minute suspension period, or you can resume them manually at the Information Center. The transceiver should be replaced, and the malfunctioning unit should be sent to your Service Provider.All alarms for a patient can be suspended/paused from the Information Center, from the TeleMon Companion Monitor, or, depending on transceiver configuration, from the transceiver itself. The Alarm Suspend/Pause duration is fixed at 3-minutes. Alarms automatically resume after 3 minutes, and can be reactivated manually earlier.
Suspending/Pausing Alarms Alarms 2-3If connected to TeleMon, alarms can be suspended only from TeleMon, and not from the Information Center, and the Alarms Suspend icon on the transceiver is lit (see “Transceiver Controls - Front” on page 1-7), and an ALARMS SUSPENDED message appears at TeleMon and the Information Center.Important—Patient monitoring (display of patient waveforms and numerics) continues for the duration of Alarm Suspend/Pause.Step Action1 To activate Alarm Pause/Suspend at the transceiver, press the Telemetry and Check buttons simultaneously. While alarms are suspended:• The transceiver illuminates the Alarms Suspend icon. • The message ALARMS SUSPENDED (or ALARMS PAUSED) is displayed in the Patient Sector at the Information Center.2 For instructions on how to pause/suspend alarms from the Information Center, see the IntelliVue Information Center Instructions for Use and the Information Center Online Help.
Suspending/Pausing Alarms2-4 Alarms Resuming/ Unsuspending AlarmsAlarms will be resumed automatically after 3 minutes. You can cancel alarm suspend manually before the 3-minute period has expired from the transceiver (see following directions) or from the Information Center.Step Action1Press the Telemetry and Check buttons simultaneously.• Auditory alarm indication at the transceiver is switched on.• The Alarm Suspend icon is turned off.• The message ALARMS SUSPENDED (or ALARMS PAUSED) is removed from the display.2 Alternately, you can unsuspend alarms at the Information Center. See IntelliVue Information Center Instructions for Use or Online Help for directions.
Standby Mode Alarms 2-5Standby ModeStandby mode is useful when the transceiver is temporarily removed from a patient or when a patient is intentionally moved out of range of an Access Point. Standby suspends monitoring so you won’t get any patient alarms or waveforms. It also disables the out of range audio signal. Patient data and current settings are preserved during the Standby period.Standby also serves to turn telemetry monitoring off when a patient is discharged. Patient data is not erased and unit default settings are not in effect until the discharge operation is performed. A bed should be put into Infinite standby until a new patient is connected to the transceiver. Monitoring can then be restarted by a click of the Resume Monitoring button. Note—To discharge a patient:1. Disconnect the patient.2. Remove batteries from the transceiver.3. Put bed in Standby.You place a patient in standby mode at the Information Center. You can select the duration of the standby period (Infinite, 4, 3, 2, or 1 hours, 30, 20, or 10 minutes). The approximate time of resumption of monitoring will be displayed. To restart monitoring, click on Resume Monitoring in the Patient Sector. Note—Unless you are discharging a patient, keep the leads attached until the patient is in Standby. If you remove the leads before putting a patient into Standby, you’ll get an ECG LEADS OFF technical alarm, as well as reminders, if configured.InitiatingStandbyStep Action1 In the Patient Window or All Controls at the Information Center, select the Standby button.2 Select the patient destination from the pre-defined list.
Standby Mode2-6 Alarms ResumingMonitoringNote—When you take an EASI patient out of Standby, the lead settings will be reset to the Information Center’s default lead settings.3 Depending on your equipment configuration, select the duration of the standby period (30, 20 or 10 minutes; 2, 3 or 4 hours; or infinite).4 Select the Suspend Monitoring button. This suspends all monitoring and displays the following messages in the Patient Sector: PATIENT LOCATION:xxx (for example, X-ray) and TELEMETRY STANDBY. The approximate time of resumption is also displayed.Step ActionStep Action1If the standby period has expired when the patient returns to the unit, monitoring will resume automatically. To verify the resumption of monitoring, press the Check button. You should hear a single beep.2If the standby period has not expired when the patient returns to the unit, monitoring must be reactivated manually. Either click Resume Monitoring at the Information Center or press the Check button on the transceiver to establish reassociation. The audible tone (single beep) at the transceiver verifies that monitoring has resumed.

ECG Safety Information3-2 ECG Monitoring ECG Safety InformationWarningWarningFor ALL Patients:Always confirm Information Center observations with clinical observation of the patient before administering interventions.Every lead must be secured to an electrode on the patient. Conductive parts of electrodes must not contact earth or other conductive parts.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.When switching from EASI to standard monitoring, there is a loss of data for 30 seconds. For PACED Patients:The output power of the transceiver 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 transceiver 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 Philips IntelliVue Telemetry System. See the IntelliVue Information Center Instructions for Use for additional information on monitoring paced patients.
Measuring ECG ECG Monitoring 3-3Measuring ECGThe electrocardiogram (ECG) measures the electrical activity of the heart and displays it on the Information Center as a waveform and a numeric. There is no cardiotach within the transceiver; cardiotach analysis resides in the arrhythmia algorithm at the Information Center. Arrhythmia analysis is always turned on for telemetry patients. Arrhythmia analysis is either basic or enhanced, depending on the product configuration.EASI ECG 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. ECG Leadsets The IntelliVue Transceiver supports 3-, 5-, and 6-wire leadsets. It detects the inserted leadset type and automatically determines the ECG measurement and transmitted leads. The Leadset Insertion Guide on the device will assist you in ensuring the correct measurement during transceiver usage (see “Connecting the ECG Cable” on page 3-19). The 5-wire leadset can be used for either standard or EASI electrode configurations. The leadsets are compatible with the 5- and 3-wire leadsets used with the IntelliVue family of monitors and with M2601B transmitters. The electrode placements for the illustrations in this chapter use the AAMI labels and colors and are summarized in the following table.Leadset Electrode Color (AAMI) Electrode Location3-wire BlackWhiteRedLARALL

Positioning ECG Electrodes3-8 ECG Monitoring Positioning ECG ElectrodesWarningWarningDo not mix and match electrodes of different types. In particular, do not use electrodes of dissimilar metals. This helps ensure optimal signal quality.WarningWarningWhen you are connecting the electrodes or the patient cable, make sure that the connectors never come into contact with other conductive parts, or with earth. In particular, make sure that all of the ECG electrodes are attached to the patient, to prevent them from contacting conductive parts or earth.WarningWarningNon-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.CautionTo protect the transceiver 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.To make it possible to compare measured ECG signals, the electrodes (or leadsets) are placed in standardized positions, forming so-called "leads". To obtain ECG signals optimized for use in diagnosis and patient management in different care environments, different leadsets in varying lead placements can be used. You can use either standard lead placements or EASI lead placements with the transceiver.
Positioning ECG Electrodes ECG Monitoring 3-9When placing electrodes on the patient, choose a flat, non-muscular site where the signal will not be impacted by either movement or bones. 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 if moved away from its correct location.In addition to correct positioning of the electrodes, optimal skin preparation prior to electrode placement will help ensure a clear signal for diagnosis.Step Action1 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.
Positioning ECG Electrodes3-10 ECG Monitoring Electrode Placement Diagrams for 5-lead standard and EASI electrode placement are located on the back of the transceiver. Additional lead placement information is available in the Online Help in the IntelliVue Information Center. Philips recommends that electrodes be changed every 24 hours.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 Electrode Placement following). Place the edge down, then "roll down" the rest of the pad. Press firmly around the adhesive edge toward the center.Note—When placing electrodes, choose a flat, non-muscular site where the signal will not be interfered with by either movement or bones. Correct lead placement is always important for accurate measurement, especially in the precordial leads, which are close to the heart. QRS morphology can be greatly altered if an electrode is moved away from its correct location.Step Action

This can be done using the Angle of Lewis.1. Locate the second intercostal space by first palpating the Angle of Lewis (the 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 just below this is the second intercostal space.2.

Verifying Electrode Connections3-22 ECG Monitoring Verifying Electrode ConnectionsThe electrode indicators enable you to verify that the leads are available for the desired monitoring. Each electrode is color-coded. Pressing and holding the Check button enables you to view the leadset status. During routine use of the transceiver for monitoring, all lead indicators are off.To verify electrode connections, use the following procedure:Step Action1 Press and hold the Check button for 2 seconds2Expected Response:• If 3-wire cable is attached: Red, White and Black indicators illuminate, then all turn off.• If 5-wire cable in Standard mode is attached: Red, White, Black, Green & Brown indicators illuminate, then all turn off.• If 5-wire cable in EASI mode is attached: Red, White, Black, Green & Brown indicators illuminate, then all turn off. The EASI indicator also illuminates briefly.• If 6-wire cable is attached: Red, White, Black, Green, Solid Brown and Brown/White indicators illuminate, then all turn off.• If no leadset is attached: all indicators are off.3Unexpected Response:Any other response indicates a problem with the transceiver. Check the leadset connection and/or use a new leadset. If the problem is not corrected, contact your Service Provider.
Monitoring during Leads Off ECG Monitoring 3-23During routine monitoring, the electrode indicators also notify you if one or more leads are not functioning. When a LEADS OFF condition occurs, the transceiver automatically illuminates the indicator corresponding to the missing lead.Monitoring during Leads OffECG Fallback and Extended monitoring states are supported for the transceiver when the primary and/or secondary leads are in a Leads Off INOP condition. Both 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. ECG Fallback must be configured on by your Service Provider.MultileadAnalysis 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 LeadAnalysis 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.Fallback forEASI 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 AI, AS, or ES lead, depending on which is available, is displayed with the label "ECG". Arrhythmia relearn is performed with transition to or from EASI Fallback monitoring using the available lead(s).
Monitoring during Leads Off3-24 ECG Monitoring Extended Monitoring Extended monitoring occurs when both the primary and secondary leads are in Leads Off for 10 seconds and another lead is available. It becomes the primary lead and the arrhythmia algorithm performs a relearn. Extended Monitoring applies if:• Telemetry is configured for Extended Monitoring ON.• The leas set provides more than two leads (e.g., when using a 5-wire leadset ).The leadset must provide more than two leads, and Extended monitoring must be configured on by your Service Provider.Relearning Whenever there is a Leads Off condition, the arrhythmia algorithm performs a Relearn, using the available leads.WarningWarningSince 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.Using EASI Leads to TroubleshootIf there is artifact in the ECG waves or a CANNOT ANALYZE ECG technical alarm condition is in effect, you can use the three EASI leads to troubleshoot:1. Click 12-Lead ECG on the Patient Window, then on 3 EASI Leads.2. The three directly acquired EASI leads will be displayed so that you can determine which electrodes are causing the problem and need to be replaced.
Optimizing ECG Measurement Performance ECG Monitoring 3-25Optimizing ECG Measurement PerformanceWhile telemetry monitoring offers many advantages, it can be a challenge. The reliability and quality of the signal transmission through the air and hospital walls is governed by a number of variables which can be difficult to control. A telemetry system cannot be as dependable as a hardwired bedside monitor that transmits its signal through a wire. The effect of interference on the Philips IntelliVue Telemetry System ranges from a momentary loss of ECG to complete inoperability, depending on the situation. The strength, frequency, and proximity of the source of interference to the transceiver devices or the access point system are factors that determine the degree of severity. In cases where the source of interference is known - for example, cellular phones, magnetic equipment such as MRI, other radio or motorized equipment - removing or moving away from the source of interference will increase the equipment's dependability. WarningWarningPhilips IntelliVue Telemetry System should not be used for primary monitoring in applications where the momentary loss of the ECG is unacceptable. In this section, we'll investigate some of the problems affecting ECG signal clarity and when possible, show you how you can greatly enhance performance.Important—Philips IntelliVue Telemetry System also emits radio frequencies that can affect the operation of other devices. Contact the manufacturer of other equipment for possible susceptibility to these frequencies.The Telemetry SignalThe transceiver worn by the patient acquires the patient's physiological data, amplifies and digitizes it, detects pace pulses and broadcasts this information via radio waves to the Philips IntelliVue Telemetry System. Since the signal passes through the air, it is susceptible to interference from many sources.
Optimizing ECG Measurement Performance3-26 ECG Monitoring Trouble- shooting Signal DisturbancesDropouts Because Philips IntelliVue Telemetry System is a wireless system, under certain conditions RF (Radio Frequency) “dropouts” can occur. Dropouts result from a weak signal or RF interference. There will be signal drops to the bottom of channel for a minimum of 200 ms to indicate to the clinical user that it is a non-physiological event. If dropouts are frequent enough to affect the heart rate count, the CANNOT ANALYZE ECG or CANNOT ANALYZE ST technical alarm occurs. The following recording strip is an example of dropouts.If frequent dropouts are occurring, the following section describes some steps you can take to improve performance.SignalStrength The Philips IntelliVue Telemetry System is custom designed for your unit, so reliable signal reception is only possible where there are receiving access points. When the signal is too low, the following technical alarms occur:• CANNOT ANALYZE ECG• CANNOT ANALYZE ST• WEAK SIGNAL• NO SIGNALTo correct, first check the location of the patient. If the patient is not in the coverage area, do one of the following.• Return the patient to the specified coverage area.• Put telemetry in Standby Mode. See “Standby Mode” on page 2-5.• If the patient is in the coverage area and is stationary, try moving the location of the transceiver from its original location by about 15 cm (6 inches).
Optimizing ECG Measurement Performance ECG Monitoring 3-27RadioFrequencyInterferenceRadio frequency (RF) interference is caused by anything that intrudes into the transmitted electrical signal, such as paging transmitters. You are probably familiar with electrical interference in our homes and cars when it causes signal loss or static with cell phones. These same types of interference can occur with the transmitted telemetry signal. Even though the Philips IntelliVue Telemetry System is designed to resist these effects, interference can occasionally be seen in the form of “dropouts”. To improve performance, the source of the interference must be identified and eliminated.Muscle and Movement ArtifactMuscle and movement artifact differ from radio frequency interference since you can prevent much of the occurrence. Noise on the ECG signal can be caused by many sources, such as interference from other electrical equipment, muscle artifact and respiratory variation. It is up to the clinician to use certain techniques to minimize these types of noise. Use the following table to help you troubleshoot the most common sources of ECG noise.Troubleshooting Common Causes of ECG NoiseProblem Cause Remedy60-Cycle (AC) Interference Poor electrode placement.Possible non-grounded instrument near patientApply fresh electrodes after recommended skin preparation.Disconnect electrical appliances near patient (one at a time) by pulling wall plugs, to determine faulty grounding. Have engineering check grounding.Muscle Artifact Tense, uncomfortable patient.Poor electrode placement.Tremors.DiaphoresisMake sure patient is comfortable.Check that electrodes are applied on flat non-muscular areas of the torso; apply fresh electrodes after recommended skin preparation if necessary (see “Positioning ECG Electrodes” on page 3-8).

ST/AR Arrhythmia Algorithm4-2 ST/AR Arrhythmia & ST Segment MonitoringST/AR Arrhythmia AlgorithmSafety InformationWarningWarningFOR ALL PATIENTSDuring 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.Learning/Relearning- Learning: If you initiate learning 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.- Relearning: When using EASI ECG monitoring, Relearn happens automatically when there is a LEADS OFF technical alarm. 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. Be sure to check the beat labels and initiate a relearn to correct.1. Respond to the technical alarm [for example, reconnect the electrode(s)].2. Ensure that the arrhythmia algorithm is labeling beats correctly.
ST/AR Arrhythmia AlgorithmST/AR Arrhythmia & ST Segment Monitoring 4-3WarningWarningFOR PACED PATIENTSIt is possible that pacemaker pulses will not be detected when the ECG analog output of a defibrillator or telemetry unit is plugged into a bedside monitor. This can result in the arrhythmia algorithm’s failure to detect pacemaker non-capture or asystole.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. Keep pacemaker patients under close observation.-- 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.-- When arrhythmia monitoring 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.For patients who exhibit intrinsic rhythm only, 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 alarms you when the patient begins pacing. Proper detection and classification of the paced rhythm can then be determined.-- 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 can result in the arrhythmia algorithm’s failure to detect pacemaker non-capture or asystole.ST/AR Arrhythmia AnalysisFor information on arrhythmia detection, refer to the following documentation:•ST/AR Algorithm - Arrhythmia Monitoring Application Note (4522 981
ST/AR Arrhythmia Algorithm4-4 ST/AR Arrhythmia & ST Segment Monitoring93051)• IntelliVue Information Center Instructions for Use and Online HelpThe intended use of the ST/AR basic arrhythmia analysis algorithm is to monitor the patient’s ECG for heart rate and ventricular arrhythmias and to produce events/alarms simultaneously for one or more ECG leads. The arrhythmia algorithm is effective when monitoring both paced and non-paced patients in a clinical environment.IntelliVue Telemetry does not have a dedicated cardiotach. Instead, the arrhythmia cardiotach at the Information Center is used. Therefore, the ST/AR Arrhythmia algorithm is always on for all IntelliVue Telemetry patients, and cannot be turned off.ST/AR provides Heart Rate and PVC Rate numerics and alarm detection for the conditions listed in the following table. There are two detection levels: Basic and Enhanced.

ST/AR ST Segment Algorithm4-6 ST/AR Arrhythmia & ST Segment MonitoringST/AR ST Segment AlgorithmWarningWarningThis device provides ST level change information; the clinical significance of the ST level change information should be determined by a physician.The ST/AR ST algorithm at the Information Center (not available for M3153A) monitors ST segment elevation or depression for each available telemetry ECG lead and produces events/alarms simultaneously. 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 non-paced and atrially-paced adult telemetry-monitored patients. With EASI monitoring, ST analysis is performed on up to 12 leads, and an additional value of ST index is calculated and displayed (see “EASI ST Analysis” on page 4-8). 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)All ST analysis and ST alarms for telemetry patients are performed by the Information Center.For additional information on ST monitoring, refer to the following documentation:•ST/AR Algorithm - ST Segment Monitoring Application Note (4522 981 92851)•Information Center Online Instructions for Use and Online HelpThe Measurement The ST measurement for each beat complex is the vertical difference between two measurement points.

ST/AR ST Segment Algorithm4-8 ST/AR Arrhythmia & ST Segment MonitoringAlgorithm Processing ST analysis analyzes ECG signals to classify the heart beats. Only beats classified as normal or Supraventricular (atrially paced) are used to calculate ST elevations and depressions.The ST/AR ST algorithm processing includes special ST filtering, beat selection and statistical analysis, calculation of ST segment elevations and depressions, and lead reconstruction and wave generation. When ST analysis is being performed on two leads, the averaged derived and reconstructed ST waves and associated ST segment values are given for up to six leads, depending on the type of patient cable:• 3-wire: one lead• 5-wire: up to two leads if monitoring a chest and a limb lead• 5-wire: up to six leads if monitoring two limb leads with the Philips Transmitter (without EASI monitoring)• 5- wire: up to 12 leads if monitoring using EASINote—No ST analysis is done on a patient if an electrode falls off.Displayed ST Data ST data displays as values in the Patient Sector and Patient Window. A positive value indicates ST segment elevation; a negative value indicates ST segment depression. You can view ST data in ST Review, Trend Review, and Event Review windows.EASI ST Analysis The Information Center generated ST values presented in the patient sector and Patient Window for EASI derived leads is 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 aVFCautionBe sure not to duplicate the lead labels. This can result in incorrect ST values being displayed for those leads.
ST/AR ST Segment AlgorithmST/AR Arrhythmia & ST Segment Monitoring 4-9ST OperationTurning STMonitoring On/OffThe ST Setup Window allows you to turn ST monitoring on or off for all available ECG leads. To turn ST monitoring on at the Information Center, perform the following steps:You would turn ST 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.Adjusting STMeasurementPointsThe ST Setup Window enables you to adjust the ST measurement points to ensure accurate data.There are three measurement cursors: • The ISO measurement cursor positions the isoelectric point in relation to the R-wave peak. • The J-point cursor positions the J-point in relation to the R-wave peak. The purpose of the J-point is to correctly position the ST measurement point.• The ST measurement cursor positions the ST point a fixed distance from the J point.Note—The ST measurement points may need to be re-adjusted if the patient's heart rate or ECG morphology changes significantly.Step Action1From the Patient Window, click the All Controls button.2From the All Controls Window, click the ST Setup button.3From the ST Setup Window, click ST On.

Each ST parameter has its own alarm limit. The alarm is triggered when the ST value exceeds its alarm limit for more than 1 minute. The alarm will be a yellow alarm. When more than one ST parameter is in alarm, only one alarm message displays. For multilead alarms when using an EASI transmitter, an alarm is generated if two or more ST leads exceed the alarm limits. The default setting is +/-1.0. The alarm message indicates the two leads that are in greatest violation of the limits, for example, “**MULTI ST AVR, V6”. If another lead becomes deviant, the message changes but it is considered the same alarm (no new alarm sounds and it is not listed as a new event).

SpO2 Safety Information5-2 SpO2 Monitoring SpO2 Safety InformationWarningWarningAlways confirm Information Center 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.Using a sensor during MR imaging can cause severe burns. To minimize this risk, ensure that the cable is positioned so that no inductive loops are formed. If the sensor does not appear to be operating properly, remove it immediately from the patient.Do not use disposable sensors on patients who exhibit allergic reactions to the adhesive.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.
SpO2 Safety Information SpO2 Monitoring 5-3WarningWarningRemoval of the SpO2 sensor during Continuous SpO2 monitoring results in a NO SENSOR technical alarm. There is no technical alarm for a "No Sensor" condition in Spot Check mode.SpO2 Information for the User1The pulse oximeter is calibrated to indicate fractional oxyhemoglobin, and displayed results can range from 0 to 100%.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.Physiological SpO2 alarm signals will be generated at the central station. The SpO2 low limit can be set between 50 and 99% inclusive, in 1% increments. The SpO2 high alarm limit can be set between 51 and 100% inclusive, in 1% increments. The maximum delay between the physiological alarm condition and alarm signal generation at the central station is 10 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.1. A functional tester cannot be used to assess the accuracy of a pulse oximeter sensor or a pulse oximeter monitor. If there is independent demonstration that a particular calibration curve is accurate for the combination of a pulse oximeter monitor and a pulse oximeter sensor, then a functional tester can measure the contribution of a monitor to the total error of a monitor/sensor system. The functional tester can then measure how accurately a particular pulse oximeter monitor is reproducing that calibration curve.
Pulse Oximetry Measurement5-4 SpO2 Monitoring Pulse Oximetry MeasurementThe ECG-SpO2 TRx+ Transceiver 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 measurement (Spot Check). The Spot Check measurement will be removed from the Information Center display after 24 hours. If 1-minute or 5-minute sampling rate is selected at TeleMon, the transceiver will provide Continuous SpO2 measurement after disconnection (see “Transceiver Use with TeleMon A02/A03” on page 1-27).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 at the Information Center is the oxygen saturation of the arterial blood - the measurement of light absorption
Selecting a SpO2 Sensor SpO2 Monitoring 5-5during a pulsation. Correct placement of the sensor is essential for accurate measurements (see “Applying the Sensor” on page 5-9).Pulse Indication During Spot Check measurement, the pulse signal is detected and communicated to you via an auditory signal. The indicator is a single low-pitch tone for each pulse detected. The tone is controlled by the Volume and Mute controls at the Information Center. The pulse indication stops when a measurement is complete. However, since it is possible to have a strong pulse but fail an SpO2 measurement, you should listen for the successful completion of a measurement (single beep), or a double beep if the measurement fails.The pulse indicator is for information only, and should not be used as an indication for treatment. The indicator is not functional in Continuous measurement mode.Clinical Note: If the transceiver is in Spot Check mode and the sensor light is illuminated but you do not hear a low-pitch sound synchronized with the pulse, readjust the sensor, or move the sensor to another site to provide better detection.Selecting a SpO2 SensorPhilips reusable sensors in adult, pediatric and infant models can be used, as well as Philips and Nellcor disposable sensors. Use only specified sensors (probes) and cables.The following chart and figure “Selecting an SpO2 Sensor” on page 5-7 guide you in selecting the correct sensor type. To use the figure, find the patient’s weight on the vertical axes. On the horizontal axis at this weight, the shaded areas indicate that the sensor is a "best choice" for the patient. Unshaded areas indicate a "good choice." For example, the best reusable sensor for a 50 kg patient is the M1191A, applied to the finger or toe. Alternatively, you could use M1194A applied to the ear.Sensor Type When to Use
Selecting a SpO2 Sensor5-6 SpO2 Monitoring WarningWarningWhen the specified Nellcor® sensors are used, the application must be consistent with the sensor manufacturer's own guidelines.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 2-3 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.See the Directions for Use supplied by Nellcor® Incorporated for instructions on preparation and application of disposable sensors.

These can contaminate sensor and electrical connections, and thereby cause unreliable or intermittent measurements.Do not use disposable sensors on patients who have allergic reactions to the adhesive.If you are using Nellcor® sensors, see the directions for use supplied with these sensors.
Applying the Sensor SpO2 Monitoring 5-9 Applying the SensorSensor Application Safety InformationWarningWarningFailure 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 and can severely obstruct circulation and lead to inaccurate measurements.Ambient Temperature: Never apply an SpO2 sensor at ambient temperatures from above 37 oC (99 oF) because this can cause severe burns after prolonged application.Extremities to Avoid: Avoid sites distal to BP cuff or intra-arterial line.Site Selection • Avoid sites with impaired perfusion, skin discoloration, excessive motion or nail polish.• Avoid placing the sensor in an environment with bright lights (if necessary, cover the sensor with opaque material).• Avoid use of excessive pressure at the application site (e.g., sensor applied too tightly, excessive adhesive tape to secure the sensor, clothing or
Applying the Sensor5-10 SpO2 Monitoring restraints that are too tight). These result in venous pulsations and inaccurate measurement, and may severely obstruct circulation.Sensor Application A minimum pulsatile flow must be present at the application site of your patient to obtain measurements. Select an appropriate sensor and apply the sensor properly to avoid incorrect measurements. Applying a small amount of pressure at the application site can improve the measurement. Use one of the preferred application sites for your sensor. Selecting the most suitable sensor and application site will help you to ensure that:• The light emitter and the photo detector are directly opposite each other and that all the light from the emitter passes through the patient's tissues,• The application site is of the correct thickness for light to pass through. If the application site is too thick or too thin, an SpO2 NON-PULSATILE technical alarm will occur. You should then select another site as appropriate.Positioning of the Light Emitters and Photo DetectorInspect the application site every 2 to 3 hours or according to clinical practice guidelines to ensure skin integrity and correct optical alignment. If skin integrity changes, move the sensor to another site.Follow the sensor’s instructions for use, adhering to all warnings and cautions.Light EmitterPhoto Detector
Applying the Sensor SpO2 Monitoring 5-11To apply the sensor, use the following directions.Adult Fingersensor(M1191A)Push the sensor over the fingertip in such a way that the fingertip touches but does not protrude from the end of the sensor. The fingertip must be uppermost and the cable must lie on the back of the hand. This ensures that the light sources cover the base of the fingertip giving the best measurement results. The cable can be held in place by the accompanying wristband.Step Action1 Select the site and appropriate sensor (see “Selecting a SpO2 Sensor” on page 5-5).2 Apply the sensor to the appropriate part of the patient’s body. Note—The application site should match the sensor size so that the sensor can neither fall off nor apply excessive pressure.3 Check that the light emitter and the photo detector are directly opposite each other. All light from the emitter must pass through the patient’s tissue.
Applying the Sensor5-12 SpO2 Monitoring WarningWarningFailure to apply the sensor properly can cause incorrect measurement of SpO2. For example, not pushing the sensor far enough over the finger can result in inaccurate SpO2 readings. Pushing the sensor too far, so that the finger protrudes from the sensor, can pinch the finger, resulting in inaccurately low SpO2 readings. Small Adult/PediatricFinger sensor(M1192A)Push the sensor over the fingertip in such a way that the fingertip touches but does not protrude from the end of the sensor.Note—When using an M1195A Infant Finger/Toe Sensor, select a finger or toe with a diameter of between 7 and 8 mm (0.27 and 0.31 inches).
Applying the Sensor SpO2 Monitoring 5-13Ear Clipsensor(M1194A)Clip the probe onto the fleshy part of the ear lobe as shown in the diagram below. The plastic fixing mechanism helps to minimize artifact generated by patient motion. Do not position the probe on cartilage or where it presses against the head.The clip sensor can be used as an alternative if the adult finger sensor does not provide satisfactory results. The preferred application site is the ear lobe, although other application sites with higher perfusion (such as the nostril) can be used. Due to the physiologically lower perfusion in the ear lobe, you should be aware of the reduced accuracy of the measurement and more frequent technical alarms.
Connecting the SpO2 Cable5-14 SpO2 Monitoring Connecting the SpO2 CableCautionExtension cables: Do not use extension cables with the IntelliVue TRx+.Step Action1 Connect the sensor cable to IntelliVue TRx+. • Connect reusable sensors directly into the transceiver.• Connect disposable sensors into the adapter cable, then connect the adapter cable to the transceiver. Remove the protective backing. 2 Ensure that the sensor and connector are positioned away from power cables, to avoid electrical interference.3 Adjust SpO2 alarms in the patient Window (see “Telemetry Controls in the Patient Window” on page 6-2).4 Make other adjustments in the Telemetry Setup Window (see “Patient-Configurable Settings in Telemetry Setup” on page 6-3).
Measuring SpO2 SpO2 Monitoring 5-15Electrical Interference: Position the sensor cable and connector away from power cables, to avoid electrical interference.Measuring SpO2SpO2 measurements can be made continuously in Continuous mode or manually on an as-needed basis in Spot Check mode, depending on the transceiver configuration. While operating in continuous mode, you can also measure pulse, and display the pleth wave at the Information Center. The SpO2 parameter is turned on by inserting/removing the sensor cable into the transceiver, or by control from the Information Center. SpO2 monitoring consumes considerable electrical energy. If the battery power is not at least 25% full, no measurements of SpO2 can be made.Setting the mode at Continuous or Spot Check is done at TeleMon or is configured using the Service Tool. Spot Check When the transceiver is configured for Spot Check measurement, use the following instructions to take an individual, manual SpO2 reading from the transceiver. You can also initiate a Spot Check measurement in the Patient Window at the Information Center by selecting the STAT SpO2 icon.Note—Spot Check measurements from the transceiver are inactive when the transceiver is connected to TeleMon. Step Action1Set SpO2 mode to Spot Check in the Telemetry Setup window.2 Attach the sensor to the patient.
Measuring SpO25-16 SpO2 Monitoring Continuous When the transceiver is configured for Continuous SpO2 measurement, use the following directions to initiate Continuous SpO2 monitoring. 3 Connect the SpO2 cable to IntelliVue TRx+, and check that:•The SpO2 sensor light turns on.• A low-pitch tone detecting each pulse is audible (unless sounds are muted).4 After approximately 30 seconds, a tone from the transceiver indicates that a measurement has been taken.The value, with the measurement time, is displayed at the Information Center.The sensor light extinguishes. If the measurement was unsuccessful, you’ll hear a double beep. Remove the sensor cable and reinsert it to retake the measurement.Note—The SpO2 value and time stamp will remain on the Information Center for 24 hours or until another measurement is taken, with one exception. If the batteries are removed from the transceiver, the Spot Check measurement will be erased from the display, but the SpO2 measurements will be available in Trend Review.5To repeat a Spot Check measurement at the bedside, disconnect then reconnect the SpO2 cable to the transceiver.Step ActionStep Action1Set SpO2 mode to Continuous in the Telemetry Setup window.2 Insert the SpO2 cable into the IntelliVue TRx+, and check that the sensor light turns on.3 Attach the sensor to the patient.
Measuring SpO2 SpO2 Monitoring 5-17Note— If the sensor is removed without discontinuing SpO2 monitoring in the Telemetry Setup Window at the Information Center, an SpO2 NO SENSOR technical alarm will result.DisplayingPulse When operating in Continuous mode, you can view pulse measurements at the Information Center. See “Patient-Configurable Settings in Telemetry Setup” on page 6-3.Note—If pulse is turned on, the Patient Sector and Patient Window of the Information Center display the label with "T" (for example, Pulse T) to indicate that the measurement was made via telemetry.DisplayingPlethWave The transceiver can be configured to transmit the pleth wave for display at the Information Center. See “Patient-Configurable Settings in Telemetry Setup” on page 6-3.SpO2 Measurement when Connected to TeleMonWhen the transceiver is connected to TeleMon:• The SpO2 measurement mode is always Continuous. 4 After approximately 15 seconds, the value, with the measurement time, is displayed at the Information Center.Note—There are no sounds associated with continuous SpO2 measurement.5 To discontinue monitoring, set SpO2 mode to off at the Information Center. Step Action
Measuring SpO25-18 SpO2 Monitoring • You can change the mode. Changes to the mode take effect when the transceiver is disconnected from TeleMon. The following settings will be used:Turning SpO2 Monitoring OffTo turn SpO2 monitoring off, disconnect the sensor cable (or adapter cable) from the transceiver. SpO2 enters a power-down mode after the cable is disconnected from the transceiver, thereby conserving battery life. SpO2 should also be turned off at the Information Center. If the transmitter is configured for Continuous SpO2 measurement and the sensor is removed without turning SpO2 off, a SpO2 NO TRANSDUCER technical alarm will result. See Important—It is important to disconnect the sensor from the transceiver. Unplugging the sensor from an adapter cable that is connected to the transceiver does NOT provide SpO2 power-down mode.

Measuring SpO2 SpO2 Monitoring 5-19Turning the SpO2 Parameter On/OffYou can turn SpO2 monitoring on/off at the Information Center. S ee “Patient-Configurable Settings in Telemetry Setup” on page 6-3.When SpO2 is turned on, the Patient Sector and Patient Window of the Information Center display a "T" next to the SpO2 numeric (for example, SpO2 T 90%) to indicate that the measurement was made via telemetry.If the transceiver is connected to the TeleMon Companion Monitor, after you turn SpO2 on, be sure to adjust the sample rate to match your patient’s acuity. When SpO2 monitoring is turned off, setting the sample rate to Spot Check at TeleMon will help you conserve the transmitter’s battery life. SpO2 Parameter Auto ONThe SpO2 parameter is automatically turned on at the IntelliVue Information Center if a manual SpO2 measurement is initiated at the transceiver while in Spot Check mode or if the SpO2 sensor is inserted into the transceiver while the transceiver is in Continuous SpO2 mode.When a patient is discharged and the transceiver is in Continuous mode, the SpO2 parameter is turned off. To reactivate the SpO2 parameter Auto ON feature from the transceiver, remember to do one of the following when a patient is discharged:– remove the SpO2 cable from the transceiver, wait 15 seconds, then reinsert the cableor– if using TeleMon, reset the transceiver to Manual mode.Note—The SpO2 parameter Auto ON feature only needs to be reactivated when the transceiver is in Continuous mode at discharge.Note— SpO2 can always be turned on and off at the IntelliVue Information Center.
Understanding SpO2 Alarms5-20 SpO2 Monitoring Understanding SpO2 AlarmsWarningWarningIf 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 sudden pulse loss or hypoxia.Physiologic SpO2 alarms will be generated and displayed at the Information Center. SpO2 offers high and low limit alarms, and a high priority (red level) oxygen desaturation alarm. The SpO2 low limit can be set between 50 and 99% inclusive, in 1% increments. The low alarm limit cannot be set below the desat alarm limit. The SpO2 high alarm limit can be set between 51 and 100% inclusive, in 1% increments.The maximum delay between the physiologic alarm condition and alarm annunciation at the central station is 10 seconds. This means that the monitor will generate an alarm if the averaged numeric value on the display exists beyond the alarm limit for more than 10 seconds.Setting the high SpO2 alarm limit to 100% is equivalent to switching off the high alarm limit. Therefore the upper alarm limit for oxygen saturation must be carefully selected in accordance with accepted clinical practices.The desaturation limit is set automatically at 10 below the Low Limit.SpO2 alarms are non-latching. That is, when an SpO2 limit is exceeded, if the alarm is not silenced, it will reset automatically if the patient’s alarm condition returns within the limits. This reduces the number of times you will need to reset alarms at the Information Center when an alarm condition has been corrected at the patient’s side (for example, movement-induced artifact alarms). See Chapter 2, “Alarms” for a list of all SpO2 alarms.
Optimizing SpO2 Measurement Performance SpO2 Monitoring 5-21Optimizing SpO2 Measurement PerformanceRefer to this section on problem situations if you have difficulty getting a signal or obtaining accurate measurements.DistortionAmbient light, motion, perfusion or incorrect sensor placement can affect the accuracy of the derived measurements. Arterial Blood FlowThe measurement depends on the pulsatile nature of blood flow in the arteries and arterioles; with the following conditions arterial blood flow can be reduced to a level at which accurate measurements cannot be made:• shock• hypothermia • use of vasoconstrictive drugs • anemiaWavelength AbsorptionThe measurement also depends on the absorption of particular light wavelengths by the oxyhemoglobin and reduced hemoglobin. If other substances are present which absorb the same wavelengths, they will cause a falsely high, or falsely low SpO2 value to be measured. For example:• carboxyhemoglobin • methemoglobin • methylene blue • indocyanine green*• indiocarmine**These chemicals are used in dye dilution cardiac output calculations.Ambient LightVery high levels of ambient light can also affect the measurement; an SpO2 INTERFERENCE message will appear on the display. The measurement quality can be improved by covering the sensor with suitable opaque material.Care and CleaningFor care and cleaning instructions, see the instructions accompanying the sensors.
Optimizing SpO2 Measurement Performance5-22 SpO2 Monitoring Optimizing Sensor PerformanceTo get the best results from your SpO2 reusable sensor:• Always handle the sensor and cable with care. The soft finger sleeve houses a sensitive electronic device that can be damaged by harsh treatment. Always protect the cable from sharp-edged objects.• Use the wristband that is supplied with your M1191A sensor. By keeping the cable between the finger sensor and the wristband fairly loose, you will maintain good monitoring conditions. Normal wear and tear associated with patient movement and regular sensor cleaning naturally mean that your sensor will have a limited lifetime. However, provided you handle the sensor and its cable with care, you can expect useful service from it for up to two years. Harsh treatment will drastically reduce the lifetime of the sensor. Moreover, Philips Medical Systems’ warranty agreement shall not apply to defects arising from improper use.

Transceiver Cleaning, Disinfection, & Cross-Infection Prevention7-8 Maintenance & Troubleshooting Note—If there is concern over cross-contamination due to leadsets or sensors, new leadsets or sensors should be used.Equipment andMaterialsWarningWarningEO is highly explosive, toxic, and a potential occupational carcinogenic and reproductive hazard. Handle it with extreme care, following U.S. Occupational Safety and Health Administration (OSHA) standards for EO (29 CFR 1910.1047)*. Personnel exposure and/or room air must be monitored per OSHA standards.Vent sterilizer gas outdoors or to a suitable, evacuated container for reprocessing, depending upon state, provincial, or country environmental regulations. Do not vent sterilant indoors.Vent aerator exhaust only to the outdoors.* See “References” on page 7-12.
Transceiver Cleaning, Disinfection, & Cross-Infection Prevention Maintenance & Troubleshooting 7-9Use the following equipment and material to process the transceiver:1. Ethylene Oxide (Allied Signal Oxyfume-2002™), heretofore referred to as EO.2. Gas sterilizer, made by American Sterilizer Company or other manufacturers.3. Mechanical aerator. The intake air for the aeration chamber must be routed through bacterial filters, and the exhaust air must be vented outside the building.Note—Available combination sterilizer/aerators bypass the problem of personnel exposure to EO during transfer of treated material to a separate aeration cabinet.Cross-InfectionProcessThe following generic procedure can be used to supplement the sterilizer and aerator manufacturers’ instructions, although the processing times, temperatures, and pressure must be the same as those given in this procedure.Important—In order to complete this stage of the process safely, harmful residue gas must be dissipated through aeration. Step Action1Remove any obvious contamination from the equipment to be processed using approved cleaners.2Individually package each transceiver in standard central supply room (CSR) wrapping material secured with EO color-change indi-cator tape.3Apply -26 inHg +/- 1 (-12.77 psig +/- .49) vacuum to the empty sterilizer chamber two times, to remove any residual EO or mois-ture. Vent the vacuum pump to the outdoors to avoid toxic hazards to personnel.4Insert the equipment to be processed into the gas sterilizer.5Heat the chamber and its contents to 54.4 +/- 2.8oC (130 +/- 5oF).6Apply -26 inHg +/- 1 (-12.77 psig +/- .49) vacuum to the sterilizer chamber.
Transceiver Cleaning, Disinfection, & Cross-Infection Prevention7-10 Maintenance & Troubleshooting 7Humidify the chamber at 50% +/- 10% relative humidity for 20 to 30 minutes.8Taking a minimum of five minutes, slowly introduce EO sterilant until the sterilizer unit pressure gauge reaches 11 +/- 1 psig.Note—At this pressure, the concentration of sterilant in the chamber will be 600 +/- 50 mg/liter, regardless of the chamber size.9Process the equipment to be processed as follows:Pressure: 11 +/- 1 psig (established in the preceding step).Time: 2-3 hoursTemperature: 54.4 +/- 2.8oC (130 +/- 5oF)10 Extract the gas mixture from the sterilizer as follows:WarningWarningComply with OSHA standards*. Do not vent sterilizer gas to the room, but vent only outdoors or to a suitable, evacuated container, depending upon state, provincial, or country environ-mental regulations. (If the mixture is captured, it can be sepa-rated commercially and the component gases re-used.)* See “References” on page 7-12.a. Pump the gas mixture out of the chamber until you ob-tain a vacuum of -26 inHg +/- 1 (-12.77 psig +/-.49), re-turning the mixture to a suitable evacuated container.b. Return the sterilizer chamber to ambient pressure by in-troducing air that has been bacterially filtered.Step Action
Transceiver Cleaning, Disinfection, & Cross-Infection Prevention Maintenance & Troubleshooting 7-11AerationProcedureWarningWarningTo avoid chemical burns and toxic effects, the equipment must be aerated after sterilization, as described. The aerator must have bacterial filters and outdoor venting.*See “References” on page 7-12. 11 Air-wash the chamber and material as follows:a. Apply -26 inHg +/- 1 (-12.77 psig +/- .49) vacuum to the chamber and processed material again, to remove residu-al EO. The vacuum pump must be vented to the out-doors.b. Return the sterilized chamber to ambient pressure by in-troducing air that has been bacterially filtered.12 Continue with the “Aeration Procedure” (following).Step Action
Transceiver Cleaning, Disinfection, & Cross-Infection Prevention7-12 Maintenance & Troubleshooting Aerate the processed equipment by performing the following steps:1 These values will produce EO and Ethylene Chlorohydrin residual levels in the transceiver and patient cable plastic that meet ISO 10993-7 in conjunction with AAMI Technical Information Report 19, that the FDA currently endorses. References OSHA: Standard for acceptable levels of personnel exposure to Ethylene Oxide Gas: 1 ppm on an eight-hour time-weighted average basis.Reference: U.S.A. Federal Regulations 49 FR 25734/29 CFR Part 1910.1047, June 22, 1984; final approval 50 FR 9800/2- CFR Part 1910.1047, March 12, 1985.Test ProcedureCautionYou must perform this test each time you put a transceiver through the cross-infection prevention procedure. This test allows you to verify that patient information for both ECG and SpO2 (if you are monitoring pulse oximetry) appear at the information center and at the bedside. You can use this procedure with a patient simulator.Step Action1To dissipate residual EO, aerate the processed equipment with air that has been bacterially filtered, using a mechanical aerator or combination sterilizer/aerator as follows:1Time: 8-9 hoursTemperature: 54.4 +/- 2.8oC (130 +/- 5oF)Ventilation Frequency: At least 30 air exchanges per hour.2 Continue with the “Test Procedure” (following).
Transceiver Cleaning, Disinfection, & Cross-Infection Prevention Maintenance & Troubleshooting 7-13Note—This test assumes that the telemetry system and Information Center are fully installed, and that you have performed the procedure to learn the transceiver identity code. Test the transceiver by performing the following steps. If the test indications do not appear, refer to your Service Provider.Step Action1Perform a mechanical inspection of the transceiver (connectors, battery door opening and closing, Telemetry and Check buttons). 2At the Information Center, select the telemetry bedside you are testing.
Transceiver Cleaning, Disinfection, & Cross-Infection Prevention7-14 Maintenance & Troubleshooting 3Test the transceiver:a. Put fresh batteries in the transceiver and close the bat-tery doorResult: All six lead lights should flash, and one light should remain on.b.
