Service Code Alarm Name/Mitigation/Resolution
3132 Ambient Pressure Fault
The ambient pressure transducer detects an altitude of <-2,000 feet below sea level (610 meters,
15.8 psig, or 1089 mb). This state can be caused by use in subterranean rescue operations or
mistaken use in a hyperbaric chamber. Beyond this pressure level, compensation remains fixed at
the -2,000 ft level
Note: The unit is not intended for use in hyperbaric chambers
Mitigation/Info: High Barometric Pressure Detected, Beyond Compensation Limit, Maintain Airway
Pressure, Check Patient Chest Rise, Monitor Ventilator/Patient
**Reduce Ambient Pressure**
3140 Operational Temperature Fault (Excessive Temperature High)
The ambient temperature exceeds the normal operating range (>131
The unit allows operation at these temperatures, but alerts the operator to the condition. Operating
above the specified range can affect the longevity of the internal battery and the duration of
operating time.
Mitigation/Info: High Temperature Detected, Remove Padded Case
**Monitor Ventilator**
3141 Operational Temperature Fault (Excessive Temperature Low)
The ambient temperature exceeds the normal operating range (<14
The unit allows operation at these temperatures, but alerts the operator to the condition. Operating
above the specified range can affect the longevity of the internal battery and the duration of
operating time.
Mitigation/Info: Low Temperature Detected, Use Padded Case
**Monitor Ventilator**
3315 Too Much Ambient Light
There is too much ambient light on the SpO2 sensor or there is inadequate tissue covering the
sensor detector.
Mitigation/Info: Shield Sensor From Light, Change Sensor Placement, Check Sensor Operation,
Replace Sensor
**Turn Off Pulse Ox Monitoring**
3450 Battery Fault (Battery Nearly Too Hot For Discharge-w/External Power Connected)
The battery temperature reaches 70
temperature and external power is connected. When the battery temperature reaches 75
°
(167 F), the battery will shut down to prevent failure. When this occurs, the unit will continue
operation using external power only.
Mitigation/Info: Battery Too Hot to Discharge, DO NOT Remove External Power!, Remove Padded
Case, Assure Ability to Manually Ventilate Patient, Shade Patient and Ventilator
**Move to Cooler Location**
3451 Battery Fault (Battery Too Hot For Discharge-w/External Power Connected)
The battery temperature reaches
battery beyond this temperature could destroy the battery and damage the unit. During the alarm
condition, the unit will continue operation using external power only.
Mitigation/Info: Battery Too Hot to Discharge, DO NOT Remove External Power!, Remove Padded
Case, Assure Ability to Manually Ventilate Patient, Shade Patient and Ventilator
**Move to Cooler Location**
