Manufacturer Narrative
|
The device was subject to on-site evaluation whereby it could be confirmed that the ventilator was not operable.The log entries demonstrate that the supervisor function of the software forced a shutdown of automatic ventilation after having detected a stalled motor.This is a safety measure to prevent from mechanical damages to the ventilator unit.The user is alerted to the shutdown of automatic ventilation by a corresponding alarm; manual ventilation remains possible and, the other device functions like gas dosage and monitoring remain unaffected.The device was in operation for 12 years now; it is seen likely that beginning wear and tear at the collector disc of the ventilator motor has led to intermittent losses of electrical contact between collector and the carbon brushes which resulted in speed fluctuations and finally to a stalling of the motor.Reportedly the user finished the surgical procedure by perfoming manual ventilation with the built-in breathing bag as intended for such error condition; no patient consequences have occurred.The number of similar cases is within the foreseen range of the device's risk management and thus accepted.
