Self Check Fault - Sensor: Barometer, Altitude Compensation Disabled
Alarm triggers when the ambient pressure transducer fails. When this occurs, the
device is no longer able to automatically compensate for changes in altitude
especially in situations where the ambient pressure could change rapidly as
during transport by air. When this alarm is active during aeromedical transport
the user should ventilate using pressure targeting if the ventilator cannot be
replaced. Users should also monitor chest rise and breath sounds to ensure
adequate ventilation.
Mitigation/Info: Sensor: Barometer, Altitude Compensation Disabled,
Maintain Airway Pressure, Check Patient Chest Rise, Avoid Use At
Varying Altitude, **Contact Service Center**
3131
Excessive Altitude - Beyond Altitude Compensation Limit
Alarm triggers when the ambient pressure transducer detects an altitude >
25,000 ft (7620 m). Beyond this altitude compensation remains fixed at the
25,000 ft compensation level. The user should monitor the airway pressure and
reduce the tidal volume as altitude increases though, there is very little change in
performance over this altitude. Where possible cabin pressure should be
maintained in the compensated range.
Mitigation/Info: Beyond Altitude Compensation Limit, Maintain Airway
Pressure, Check Patient Chest Rise, Monitor Ventilator/Patient,
**Reduce Altitude/ Pressurize Cabin if Possible**
3132
Low Altitude - High Barometric Pressure Detected, Beyond Compensation
Limit
Alarm triggers when the ambient pressure transducer detects an altitude
≤
2,250
ft (
≤
685.8 m) below sea level (15.8 psig or 103 kPa). This can be caused by use
in a subterranean rescue operation or mistaken use in a hyperbaric chamber.
Beyond this pressure level compensation remains fixed at the -2,000 ft level.
NOTE: the device is not intended for use in hyperbaric chambers or at
hyperbaric pressures.
Mitigation/Info: High Barometric Pressure Detected, Beyond
Compensation Limit, Maintain Airway Pressure, Check Patient Chest
Rise, Monitor Patient and Ventilator, **Reduce Ambient Pressure**
3140
Ambient Temperature Fault - High Temperature Detected
Alarm triggers when the ambient temperature exceeds the normal operating
range, > 55 °C (131 °F) for the ventilator. The device allows operation at these
temperatures but alerts the user to the condition. Operating above the specified
range can affect the longevity of the internal battery and the duration of operating
time. When operating at high temperatures the user should remove the padded
case which insulates and increases the ventilator’s internal temperature.
Mitigation/Info: High Temperature Detected, Remove Padded Case,
**Monitor Patient and Ventilator**
