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.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
There is a potential for inadvertent tidal volume knob movement from the original setting when set at high (1000-1500 mL) and low (70-150 mL) settings.
- RECALL
When a paraPAC plus ventilator is switched to the operating mode of VENTILATE, the ventilator may intermittently provide continuous positive gas flow instead of the intended cycling like a human breath. This non-cycling and continuous positive gas flow when in the cycling mode, is a malfunction, not allowing the ventilator to properly function as designed.
- RECALL
Two devices were labeled with the same serial number
- RECALL
Smiths Medical is conducting a recall of 93 Pneupac VR1 Emergency & Transport Ventilators following the identification of a problem which may exist with the demand valve that could cause the ventilator to stop cycling & to deliver continuous flow output to the patient.
- RECALL
A potential safety related problem associated with the Pnuepac babyPac Ventilator model 100 has been discovered in that the interface between the air input hose and the air input fitting may leak, and if tightened too much, the air input fitting may loosen when trying to remove the air hose.
