3132 Low Altitude
Alarm triggers when the ambient pressure transducer detects an altitude <-2,000 feet below sea level (610
meters, 15.8 psig or 103 kPa). This can be caused by use in 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
Alarm triggers when the ambient temperature exceeds the normal operating range, >131 °F (55 °C) 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**
3141 Ambient Temperature Fault
Alarm triggers when the ambient temperature falls below the normal operating range <14 °F (-10 °C) for the
ventilator. The device allows operation at these temperatures but alerts the user to the condition. Operating
below the specified range can affect the longevity of the internal battery and the duration of operating time. At
extreme cold temperatures operating time can be significantly reduced. When operating at low temperatures
the user user use the padded case which insulates and increases the ventilator's internal temperature.
Mitigation/Info: Low Temperature Detected, Use Padded Case, **Monitor Patient and Ventilator**
3143 Self Check Fault
Alarm triggers when there is failure of the internal temperature sensors. When this occurs the device is no lon-
ger able to detect if it is operating outside of the allowable temperature range. If operating inside of the stan-
dard temperature range -25 °C to 49 °C (-13 °F to 120 °F) there is no effect on operation. If operating outside
this range the user should monitor the device continuously. When appropriate the user should replace the ven-
tilator and contact the service center for additional information.
Mitigation/Info: Environmental Sensor: Temperature, Ventilator Operating, Service Required, **Contact Ser-
3172 Self Check Fault
Alarm triggers when the device is not able to zero the airway pressure transducer during the autocal cycle.
When this occurs the device is still able to monitor the airway pressure safely. Large changes in temperature
should be avoided which can affect the calibration of the transducer. This alarm can also be triggered when the
device is exposed to excessive vibration and/or is mounted in a vehicle in a manner that increases its expo-
sure to vibration. If the alarm continues, replace the ventilator and contact the service center for additional
information.
Mitigation/Info: Pneumatic Sensor: Autocal, Reduce Vibration if Possible, Avoid Temperature Changes, Auto-
3300 Self Check Fault
Alarm triggers when the pulse oximeter module fails and the user has turned off pulse oximeter monitoring
acknowledging the condition. When this is done "stby" appears in the parameter windows for SpO
those parameters are no longer available. When appropriate the user should replace the ventilator and contact
the service center for additional information.
Mitigation/Info: Pulse Ox Module Not Available, SpO2/HR Not Available, **Contact Service Center**
3301 Self Check Fault
Alarm triggers when the communication between the pulse oximeter module and device fails and the user has
turned off pulse oximeter monitoring acknowledging the condition. When this is done "stby" appears in the
parameter windows for SpO
should replace the ventilator and contact the service center for additional information.
