2172 Spont. Breath Vt High
Alarm triggers when the high VT Limit is exceeded during 2 consecutive spontaneous breaths. The user
should check: the patient connection, airway placement, breathing circuit for loose hoses/ tubes and also
check the exhalation valve. The user should also check if the High VT Limit is set correctly. While resolving
the alarm condition the user should be sure to manually ventilate the patient.
Mitigation/Info: Check Patient Connection, Check Circuit for Loose Hose/Tube, Check Exhalation Valve,
Check Tube Placement/ Cuff, Check Limit Setting, **Monitor Patient**
2173 Spont. Breath Tt Low
Alarm triggers when the Low VT Limit Setting is not achieved during 2 consecutive spontaneous breaths.
When this occurs, the user should quickly check for kinked hoses/ tubes and check for airway obstruction.
The patient should be suctioned if necessary. The user should also check if the Low VT limit is set correctly.
While resolving the alarm condition the user should be sure to manually ventilate the patient.
Mitigation/Info: Check Circuit for Kinked Hose/Tube, Check for Airway Obstruction, Suction Airway if Neces-
sary, Check Low Limit Setting, **Manually Ventilate Patient**
2300 Self Check Fault
Alarm triggers when the pulse oximeter module fails while in use. The user cannot resolve the fault. When the
alarm is active "-- --" displays in the HR and SpO
audible alarm for 30 seconds. To resolve the alarm, remove the probe from the device and put the pulse
oximeter in standby "stby". Contact the service center for additional information.
Mitigation/Info: Pulse Ox Module, Internal Failure, SpO2/HR Not Available from Pulse Ox, Turn Off Pulse Ox,
2301 Self Check Fault
Alarm triggers when the communication between the pulse oximeter module and device fails. When this
occurs the user must turn off the pulse oximeter monitor to end the alarm condition through the SpO
menu while also removing the probe from the device. When this is done "stby" appears in the parameter win-
dows for SpO
replace the ventilator and contact the service center for additional information.
Mitigation/Info: Internal COMM: Pulse Ox Module, SpO2/HR Not Available from Pulse Ox, Turn Off Pulse
Ox, Remove SpO2 Cable from Ventilator, **Contact Service Center**
2314 Pulse Ox Sensor Off Patient
Alarm triggers when an operating sensor loses the patient signal. The most common cause is when the sen-
sor disconnects from the patient or is misaligned with the sensor site. This alarm can also be caused by poor
perfusion at the sensor site which doesn't provide an adequate signal. In these cases try another site.
Replace the sensor if another sensor is available. If the alarm condition cannot be resolved the user should
remove the sensor from the patient and put the pulse oximetry monitor in standby "stby".
Mitigation/Info: Check Pulse Ox Sensor Site, Check Patient for Peripheral Pulse, Change Placement, Check
Sensor Operation, Replace Sensor,**Turn Off Pulse Ox Monitoring**

2410 Heart Rate High
Alarm triggers when the heart rate is greater than the High Heart Rate Limit. The default value for the limit is
120 beats/minute. The user should consult with the attending physician on how best to reduce the heart rate
to an acceptable level.
Mitigation/Info: Heart Rate Above Limit, Check High Limit Setting, **Consult Physician**
