Covidien Puritan Bennett 980
Covidien · Model Puritan Bennett 980
Intuitive and highly configurable touch screen Graphs may be scaled and enlarged to full screen to improve visibility. Using the pause button, you can pause the screen and review the last 60 seconds of patient data. In situations where you may not be directly in front of the screen, or during teaching situations where there are several people in the room, the large-font screen can provide greater visibility to patient data Screen configurability Several configuration options enable you to see as little or as much information as you need. Patient data in the top banner may be configured to the patient need or to match your workflow document. Additional patient data can be accessed by scrolling right to left in the upper right corner. Patient data cells may be left blank to reduce the amount of visible patient data.
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.
Flow / pressure sensor drift
MediumSymptoms: Inaccurate delivered volume, false volume/pressure alarms.
Root cause: Sensor contamination or aging of differential-pressure transducer.
Power supply / battery failure
HighSymptoms: Unexpected shutdown, persistent low-battery alarm.
Root cause: Aged internal battery or failed PSU.
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.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Any single affected ventilator should only be used for the 10- year labelled service life, but if longer ventilatory support is required using more than one ventilator over time, the use of these devices for more than 14 years of cumulative duration may pose harm to health due to a volatile organic compound (VOC), 2-propanol, 1,3-dichloro released from some components in the ventilator gas pathway
- RECALL
Inadequate internal fixation of the power inlet port to the cuff pressure manager device causes the external power inlet to became dislodged within the device housing after several uses, which prevents the device from being charged, and could lead to treatment delay.
- RECALL
Covidien is conducting a voluntary field corrective action on Puritan Bennett 840 ventilator systems with certain software revisions in response to customer reports of ventilator diagnostic code XB0069 in which the device stops mechanical ventilation due to a software error.
