Manufacturer Narrative

Based on the available log file, the reported case could be reconstructed.It was found that during the case in question, a sporadic failure of the inspiratory pressure sensor of the vgc (ventilation and gas controller) was detected by the device.In consequence, the ventilator initiated an autonomous shutdown while changing mode (pressure mode) to man/spont accompanied by the corresponding "ventilator fail" alarm as specified.In this case, manual ventilation as well as monitoring function remains unaffected, the user continued ventilation in man/spont.One minute later the automatic ventilation was available again and the procedure was continued towards the end.Dräger finally concludes that the device reacted as specified upon a sporadic failure of the inspiratory pressure sensor.The device was tested according to manufacturers specification and returned into use.The number of similar cases, related to the same root cause, is within the expected range of the respective risk assessment and thus accepted.
