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.
Exhalation valve leak / failure
HighSymptoms: Low exhaled tidal volume, high leak alarm, inability to maintain PEEP.
Root cause: Diaphragm/valve degraded by secretions and cleaning cycles.
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
Affected devices have a smaller diameter than expected and may potentially result in inadequate ventilation to the patient. Patient may experience hypoxia, underdose, or cardiopulmonary collapse.
- RECALL
Uncertainty in the seal integrity of the sterile packaging.
- RECALL
The incorrect device is contained in the package.
- RECALL
One lot number of a specific model of ULTRAperc Percutaneous Dilation Tracheostomy Kit, 9.0mm may have been incorrectly labeled as a 7.0mm ID kit.
- RECALL
The labeling was missing information on sterilization and prohibition of reuse.
- RECALL
Smiths Medical became aware that one lot of the 8.0mm UniPerc(R) Adjustable Flange Tracheostomy Tube kit, product reorder number 100/897/080 CZ, lot number 3308971, contains an incorrect 9.0mm sized obturator instead of the correct 8.0mm sized obturator.
- RECALL
Visible orange/ brown particulate on the needles of the 29g Hypodermic Needle-Pro Fixed Needle Insulin Syringes
- RECALL
Pediatric Trachel Tube manufactured with internal diameter smaller than indicated in the label may result in inability to remove secretions and cause partial or complete obstruction of the airway
- RECALL
Smiths Medical noticed an increased trend in leakage associated with 100 ml CADD Medication Cassette Reservoirs Reorder Number 21-7002-24 Lot Numbers 213X18 and 214X18. If a leak occurs in a CADD medication Cassette Reservoir, it may allow spillage of medication, contamination of the fluid path, and/or air to enter the Reservoir. Smiths Medical has not received any report of patient injuries due
- RECALL
Smith Medical has become aware that an increase in pH may occur with some medications when instilled in the Affected Cassettes. Also, a small number of catheter occlusions have been reported from one customer when these Affected Cassettes have been used for delivering Flolan.
- 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.
