Key tips
- ·Never disable a low-pressure/circuit-disconnect alarm while troubleshooting - silence it, don't disable it.
- ·Verify the O2 supply source and pressure before assuming an internal fault.
- ·Circuit type must match the patient population (adult/pediatric/neonatal) - a mismatched circuit invalidates delivered volumes.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Fails the pre-use self-test / circuit check
HighSymptoms: Self-test fault, circuit-leak or compliance-check failure, will not be released for use.
Root cause: Patient-circuit / expiratory-valve leak, a flow-sensor fault, an O2-cell fault, or an internal pneumatic fault.
Flow / volume delivery inaccurate
HighSymptoms: Delivered tidal volume or flow does not match the setting, or fails the annual verification.
Root cause: Flow-sensor drift / contamination, an inspiratory / expiratory valve fault, or a blender / proportioning-valve fault.
O2 / air supply or blender fault
MediumSymptoms: Low-supply alarm, FiO2 not matching the setting, O2-cell reads wrong.
Root cause: Wall / cylinder supply issue, an inlet filter / regulator fault, the blender, or an aged O2 cell.
PEEP not held / high circuit pressure
MediumSymptoms: PEEP drifts, auto-PEEP, high-pressure alarms, poor exhalation.
Root cause: Worn or wet expiratory valve / diaphragm, or a blocked exhalation path.
Battery / power fault
MediumSymptoms: Short internal-battery run time, will not charge, transfers to battery unexpectedly.
Root cause: Aged internal battery or a power-supply fault.
Turbine / compressor fault (turbine units)
MediumSymptoms: Noisy operation, cannot meet flow demand, turbine / compressor alarm.
Root cause: Worn turbine / compressor.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily pre-use check: self-test, circuit integrity, alarm function
- ·Scheduled circuit and inspiratory filter replacement per manufacturer interval
- ·Flow and pressure sensor calibration verification
- ·Battery load test and runtime check
- ·Annual full PM and electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Fails the pre-use self-test
- Run the self-test with the exact circuit and humidifier that will be used.
- Leak-test the circuit and the expiratory valve; fit fresh flow sensors and an O2 cell if due.
- Repeat the self-test.
- Calibrate the O2 cell and flow sensors per the manual.
- Remove from service and refer an internal pneumatic fault to the OEM / biomed.
Symptom: Delivered volume or FiO2 wrong
- Verify tidal volume / flow with a calibrated gas-flow analyser and FiO2 with an analyser at the wye.
- Calibrate the flow sensors and O2 cell.
- Inspect the inspiratory / expiratory valves.
- Check the air / O2 supply pressures and inlet filters.
- Refer the blender / proportioning valve for service if the mix is still wrong.
