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.
Mitigation/Info: Check Circuit for Kinked Hose/Tube, Check for Airway
Obstruction, Suction Airway if Necessary, Check Low Limit Setting,
**Manually Ventilate Patient**

Self Check Fault - Pulse Ox Module, Internal Failure
Alarm triggers when the pulse oximeter module fails while in use. The user
cannot resolve this fault. When the alarm is active “-- --” displays in the HR and
SpO
2
windows. Pressing the Mute/Cancel button silences the 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.

Self Check Fault - Internal COMM: Pulse Ox Module
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
2
Context menu while also removing
the probe from the device. When this is done “stby“ displays in the parameter
windows for SpO
2
and HR as those parameters are no longer available. When
appropriate the user should replace the ventilator and contact the service center
for additional information.

Pulse Ox Sensor Off Patient
Alarm triggers when a pulse oximeter sensor loses the patient signal. The most
common cause is when the sensor 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**
