Device Alarms - ZOLL 731 Series Operator's Manual

Device Alarms

Device alarms are triggered by a malfunction or internal fault with the ventilator device.
Service Code Alarm Name/Mitigation/Resolution
1001 Compressor Failure (Compressor Control Fault - No Backup)
The compressor fails to operate or fails to provide the flow required to deliver a breath and
high-pressure oxygen (HP O
Mitigation/Info: Manually Ventilate Patient, Connect HP O
**Replace/Service Ventilator**
1002 Compressor Failure (Compressor Signal Chain Fault - No Backup)
Communication between the compressor controller and Smart Pneumatic Module (SPM) is lost and
high-pressure oxygen (HP O
Mitigation/Info: Manually Ventilate Patient, Connect HP O
**Replace/Service Ventilator**
1003 Self Check Failure
The flow from the first breath is ±20% of the expected flow for the tidal volume at start up. This
unusually low RPM is a symptom of a dirty flow screen which cannot be serviced by the operator.
Mitigation/Info: Manually Ventilate Patient
**Replace/Service Ventilator**
1010 O2 Valve Failure (O2 Valve Failed Open)
The O2 Valve fails in the open position which results in continuous inspiratory flow. When this
occurs, the unit automatically opens the exhalation valve to prevent pressure from accumulating in
the circuit and ventilation stops.
Mitigation/Info: Manually Ventilate Patient
**Replace/Service Ventilator**
1011 O2 Valve Failure (O2 Valve Control Fault - No Back Up)
The signal to the O
available to provide ventilation.
Mitigation/Info: Manually Ventilate Patient

1012 O2 Valve Failure (O2 Valve Signal Chain Fault - No Back Up)
The communication between the O

1020 O2 Supply Pressure Low
The oxygen supply pressure is
If the oxygen source can be restored, the unit should be cycled off then on to reset. By design, the
unit will not reestablish oxygen operation unless the supply pressure is
