Based on the log file analysis, the case in question 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.The device reacted as specified in consequence, by initiating an autonomous shutdown while changing 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.Dräger finally concludes that the device reacted as specified upon a sporadic failure of the inspiratory pressure sensor.The device was tested according to manufacturer's specification and returned back to use without further problems reported.The number of similar cases, related to the same root cause, is within the expected range of the respective risk assessment and thus accepted.
