Puritan Bennett
Covidien LP · Model 980X1DENISS
A mains electricity (AC-powered) automatic cycling device intended to provide long-term alveolar ventilation support for the full age-range of patients, from neonatal, paediatric to adult, in a critical care setting. It typically uses positive pressure to deliver gas at normal breathing rates and tidal volumes through an endotracheal (ET) tube or tracheostomy, and consists of a breathing circuit, a control system, monitors, and alarms. The inhalation limb includes sites where inspired gas may be heated/humidified, and the exhalation limb includes an exhaust valve to release gas to the ambient air. It can be operated in several modes (e.g., assist/control, synchronized, patient triggered).
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.
Will not power on or unexpected shutdown
HighSymptoms: The ventilation & respiratory is dead, reboots, or shuts down mid-use.
Root cause: Mains lead / fuse, an aged battery, or a power-supply board fault.
Battery will not hold charge
MediumSymptoms: Short run time on battery; low-battery alarm soon after a full charge.
Root cause: Aged rechargeable battery pack or a charger fault.
Display / control-panel fault
MediumSymptoms: Blank, dim or distorted display; unresponsive keys or touchscreen.
Root cause: Display, backlight, or control-board fault.
Fails self-test or calibration
MediumSymptoms: Power-on self-test or the scheduled performance check fails or is out of tolerance.
Root cause: Sensor drift or an internal board fault; recalibration or repair needed.

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 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: Will not power on
- Confirm the outlet, mains lead and fuse.
- Try on battery, then on mains only, to isolate the supply.
- Look for a power indicator or POST code.
- Replace the fuse / battery / power supply as isolated.
- Run the self-test after any repair.
Symptom: Fails self-test or calibration
- Note the exact failure message / code.
- Power-cycle and repeat the self-test.
- Verify against a reference / simulator where one applies.
- Recalibrate per the service manual.
- Refer the affected board for service if it will not hold calibration.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Medtronic has confirmed six reports from customers outside the US where the ventilator became inoperable due to loss of gas supply caused by manufacturing error of specific turbine components.
- RECALL
Manufacturing assembly error where a capacitor within the ventilator was assembled incorrectly, which may cause the device to become inoperable during use.
- RECALL
In-house lab observations and customer reports of overheating and/or thermal damage to the battery pack, create the risk of exposure to smoke or hazardous materials, which may result in burns and/or bronchospasm,
- RECALL
Software Update: External USB Drive performance and its impact on Graphic User Interface (GUI) functionality and labeling of the scalar waveform displayed on GUI during ventilation
- RECALL
Rechargeable lithium-ion batteries with incorrect firmware that are used in certain Puritan Bennett 980 ventilators may not fully charge after installation.
- RECALL
Graphical user interface (GUI) unresponsive to touch and Loss of primary ventilation under certain circumstances. Covidien Respiratory and Monitoring Solutions, now a part of Medtronic, issued a field corrective action notice for two issues on all models of Puritan Bennett 980 (PB980) ventilator.
- RECALL
Reports in which tidal volumes reaching patients were lower than set tidal volumes in neonatal Volume Control Plus (VC+) Mode with active humidification. This situation may potentially lead to respiratory compromise if not recognized.
- RECALL
Covidien is issuing a voluntary field action for all Puritan Bennett 980 ventilators due to occasional GUI transient resets that last approximately 30 seconds.
- RECALL
CO2 detector may increase resistance to air flow in an intubated patient.
- RECALL
Difficulty inserting an obturator and/or suction catheter into the tracheostomy tube.
- RECALL
Wiring in battery back-up power supply may short and cause thermal damage to ventilator.
