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 / extended self-test
HighSymptoms: Self-test aborts with a diagnostic code, circuit-leak or compliance test fails, ventilator not released for use.
Root cause: Patient-circuit leak, an exhalation-valve / flow-sensor fault, or an internal pneumatic / electronic fault (see the diagnostic-code table).
Oxygen / air delivery or blender fault
HighSymptoms: FiO2 not matching the setting, low or high supply-pressure alarm, gas-mix alarm.
Root cause: Blender fault, a wall-supply / hose issue, or a failing internal compressor / turbine.
Flow / pressure sensor drift
MediumSymptoms: Monitored tidal volume, pressure or flow implausible, frequent nuisance alarms.
Root cause: Flow sensor(s) or the internal pressure transducers aging or contaminated.
Exhalation-valve fault
MediumSymptoms: PEEP not held, auto-PEEP, high circuit pressure, exhalation-valve alarm.
Root cause: Worn or wet exhalation-valve diaphragm / assembly.
Battery / power fault
MediumSymptoms: Short battery run time, will not ride through a power interruption, will not charge.
Root cause: Aged internal / external battery.

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: Self-test / circuit test fails
- Run the extended self-test (EST) with the exact circuit that will be used, and note the diagnostic code.
- Look the code up in the service manual's diagnostic-code table and follow the sequenced repair actions.
- Leak-test the patient circuit, humidifier and water traps.
- Fit a fresh flow sensor and exhalation valve and repeat.
- Verify secure connections of all cables and modules; replace CPU / main boards only after all other remedies.
Symptom: FiO2 or supply-pressure fault
- Confirm the O2 (and air) supply pressures and hoses.
- Verify FiO2 with a calibrated analyser at the wye.
- Calibrate the O2 sensor / blender per the service manual.
- Listen for the internal compressor / turbine cycling correctly on air-supply loss.
- Refer the blender / compressor for service if the mix is still wrong.
