The user facility did not involve the local dräger s&s organization into evaluation or repair of the device.The device was manufactured in august 2011 but the status of preventive maintenance and repairs is unknown.The hospital engineering dept.Suspected a failed power supply or motor assembly - but no further information or additional details about the event and follow-up could be obtained.The lack of information does not allow a case-specific evaluation and no reliable conclusion in regard to the potential root cause.In fact, it can even not be confirmed that indeed a ventilator failure has occurred.The manufacturer finally concludes - given that a malfunction of the device has occurred - the device is designed to post a corresponding alarm if automatic ventilation fails.There's a breathing bag integrated to ensure that patient support can be done by means of manual ventilation; a ventilator shut-down has no effect on the gas dosage and the monitoring functions.An assessment which scenario may apply for this particular event is not possible due to missing relevant information.The event may have been the consequence of a component malfunction, an use error or an infrastructure issue.
