During on-site checking in follow-up to the event, the draeger service technician detected three faulty parts (pressure transducer on a control pcb, the electronical peep valve and the light barrier) and replaced them accordingly.Afterwards, the device was tested and confirmed to be operating per manufacturer¿s specification.The parts as well as the electronic device logfile were requested for investigation at the manufacturer¿s site but were unfortunately not available.Since the device is almost 18 years old, it is likely that the vent fail was caused by wear and tear of (one of) the replaced component(s).However, due to lack of information, a differentiation is not possible.Checking the ventilator operation is part of the daily and pre-use check (described in the instruction for use) and must be carried out before each patient use.Based on the given information, it can be concluded that the ventilator failure was related to the aspect that the supervisor function of the fabius system detected an issue that forced a shut-down of automatic ventilation according to its safety concept.Such a ventilator shutdown is accompanied by the corresponding vent fail alarm.The user can switch to manual ventilation as described in the instructions for use.Monitoring is still functional.
