Since neither the requested logfile nor the parts were returned, a detailed analysis of the case in question as well as the determination of the root cause was not possible.In case of a ventilator failure during automatic ventilation, the ventilator initiates an autonomous shutdown while changing mode to man/spont (safety mode) and generating the appropriate ventilator fail alarm.Manual ventilation remains possible.Based on the available information, the root cause for the reported ventilator failure could not be determined but it can be assumed that the device reacted as specified with an autonomous change to manual ventilation and alarmed audible and visible for ventilator fail.
