Exhalation System Failure - Patient Can Not Exhale
Alarm occurs when the PIP fails to return to the baseline pressure for 3
consecutive breaths, indicating that the exhalation control valve has failed. When
triggered, the device stops ventilating and attempts to discharge the pressure in
the breathing circuit to atmosphere. This failure may be caused by a significant
blockage of the exhalation valve or an occlusion/kink in the exhalation valve
tube. If possible, the user should replace the breathing circuit and restart the
ventilator. If this does not resolve the failure, replace the ventilator and contact the
service center for additional information.

Exhalation System Failure - Patient Can Not Exhale
The airway pressure, PIP, is > 40 cm H
2
O, the PIP High Limit (when PIP High
Limit is < 35 cm H
2
O) for > 5 seconds, or when the PIP is > 75 cm H
2
O for > 1.5
seconds. When this happens, the device stops ventilating and attempts to
discharge the pressure in the breathing circuit to atmosphere. This failure may
be caused by a significant blockage of the exhalation valve or an occlusion/kink
in the exhalation valve tube. If possible, the user should replace the breathing
circuit and restart the ventilator. If this does not resolve the problem, replace the
ventilator and contact the service center for additional information.

Self Check Failure - Pneumatic Sensor: Autocal
Alarm occurs when the 5 VDC power bus fails to provide the required voltage. If
this failure occurs, the user should manually ventilate the patient, replace the
ventilator and contact the service center for additional information.
Mitigation/Info: Pneumatic Sensor: Autocal, Manually Ventilate Patient,
**Contact Service Center**
1173
Self Check Failure - Internal COMM
Alarm occurs when communication fails between one of the subcomponents and
the host processor. If this failure occurs, the user should manually ventilate the
patient, replace the ventilator and contact the service center for additional
information.
Mitigation/Info: Internal COMM, Manually Ventilate Patient, Backup
Ventilator Started, **Contact Service Center**
1174
Self Check Failure - Pneumatic Sensor: Transducer
Alarm occurs when the device is not able to calibrate one or more transducers
and is no longer able to operate safely. If this failure occurs, the user should
manually ventilate the patient, replace the ventilator and contact the service
center for additional information.
Mitigation/Info: Pneumatic Sensor: Transducer, Manually Ventilate
Patient, Restart Ventilator, **Contact Service Center**
