Multi-Function Ventilators were serviced using incorrect parts which have the potential to cause unexpected shutdown, or when using an active circuit could result in inaccurate tidal volume monitor, not triggering on patient efforts, less inspiratory volume, less inspiratory pressure, and less PEEP delivered.
The bonded spiral wrap may detach before or during ventilation due to a manufacturing issue. Detachment of the spiral wrap can compromise structural integrity, functionality and/ or performance resulting in occlusions or leaks of the breathing circuit which may cause serious injury or death. The risk of injury or death is increased for ventilator dependent patients.
Due to a component failure, ventilators may unexpectedly shut down or have a loss of blower function while in patient use. The shutdown potentially prevents the ventilator from providing ventilation therapy.
