The user facility did not involve the local dräger s&s organization into evaluation or repair of the device.The device was manufactured in june 2014 but the status of preventive maintenance and repairs is unknown.The user/hospital suspected that a jammed piston of the ventilator assembly caused the problem but on request to obtain further information no additional details about the event and follow-up has been provided.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.H3 other text : on-going.
