Service Code Alarm Name/Mitigation/Resolution
2053 Suspicious Triggers
Airway pressure sensor fails to calibrate the expiratory phase of a breath. When this occurs, the
unit attempts to reestablish a baseline by momentarily setting PEEP to 0 cm H
triggered breaths. This interruption lasts no longer than 2 breath cycles.
Mitigation/Info: Attempted Self-Calibration, Momentarily Disabling Triggers and PEEP, Check
Circuit for Leak/Disconnects, Check Tube Placement/Cuff
**Replace/Service Ventilator**
2062 Exhalation Fault
The airway pressure (P
pressure (PEEP pressure).
Mitigation/Info: Check Circuit for Kinked Hose/Tube, Check for Blocked Exhalation Valve, Replace
Circuit, Replace/Service Ventilator

this occurs, flow decelerates to maintain P
the breath (inspiratory time).
Mitigation/Info: Pressure Exceeds Limit Setting, Check Circuit for Kinked Hose/Tube, Check for
Airway Obstructions, Suction Airway if Necessary, PIP High Limit Set Too Low?

Mitigation/Info: Check Patient Connection, Check Circuit for Loose Hose/Tube, Check Exhalation
Valve, Check Tube Placement/Cuff, Is High Limit Set Correctly?
**Manually Ventilate Patient**
2072 High Tidal Volume
Operating with a pressure target and the delivered tidal volume exceeds the operator defined limit
for 2 consecutive breaths.
Mitigation/Info: Check Patient Connection, Check Circuit for Loose Hose/Tube, Check Exhalation
Valve, Check Tube Placement/Cuff, Is High Limit Set Correctly?
**Monitor Patient**
2073 Low Tidal Volume
Operating with a pressure target and the delivered tidal volume does not reach the operator defined
limit for 2 consecutive breaths. When this occurs, flow decelerates to maintain the P
pressure limit for the duration of the breath (inspiratory time). If the PIP setting is set properly, the
breath should be greater than the low limit (provided it is set properly as well).
Mitigation/Info: Check Circuit for Kinked Hose/Tube, Check For Airway Obstruction, Suction Airway
If Necessary, If Low Limit Set Correctly?
