The responsible technician reportedly checked the device on-site and traced the issue back to the ventilator motor.The entire motor assembly was replaced, consequently.Even though requested, logfiles were not received for detailed root cause analysis.In case the fabius device shuts down automatic ventilation, the device will generate an audible alarm and a visible alarm message "ventilator fail" will be displayed.In this case, automatic ventilation is not possible.The user can switch to manual ventilation as described in the instructions for use.Monitoring is still functional.The motor asm has brushes, ball bearing, commutator disk and a spindle which are affected from aging caused by wearing.The device was in operation for approx.15 years.The motor is designed for a lifetime of ten years at standard operating conditions (5hours/day, 5 days/week).A wear-and-tear related end of life for this component can be considered well-acceptable.The replacement of the affected motor asm by the responsible technician has already solved the problem, no patient consequences have reportedly occurred.The number of similar cases, related to the same root cause, is within the expected range of the respective risk assessment and thus accepted.
