Airon pNeuton S
Airon · Model pNeuton S
Calibrated CPAP and oxygen controls for easy operation MRI conditional up to 3 T – place right next to the scanner with remote alarm output for the control room Manometer to monitor patient pressure and effort Built-in CPAP / PEEP system with automatic sensitivity for changing patient needs; no need for external CPAP valves Night visible pressure gauge for patient monitoring Monitor CO2 with invasive/non-invasive ventilation Oxygen powered – no batteries to change Rugged and lightweight (6 lbs / 2.7 kg) Use the bacteria / viral filter to protect caregiver from patient exhalation
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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Compressor / turbine failure
HighSymptoms: Unable to reach set pressure, low-flow alarm, loud noise.
Root cause: Worn bearings or failed blower motor.
Power supply / battery failure
HighSymptoms: Unexpected shutdown, persistent low-battery alarm.
Root cause: Aged internal battery or failed PSU.
Patient circuit leak
LowSymptoms: Leak alarm, low circuit pressure, volume loss.
Root cause: Disconnected or punctured patient circuit / humidifier.
O2 blender / mixer fault
MediumSymptoms: FiO2 out of range, oxygen alarm.
Root cause: Failed solenoid or proportional valve in blender.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Exhalation valve leak / failure
- Confirm the presentation - typically low exhaled tidal volume, high leak alarm, inability to maintain PEEP - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: diaphragm/valve degraded by secretions and cleaning cycles.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the exhalation valve assembly per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Flow / pressure sensor drift
- Confirm the presentation - typically inaccurate delivered volume, false volume/pressure alarms - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: sensor contamination or aging of differential-pressure transducer.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the flow / differential pressure sensor per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
