It was reported that the operator observed during use that the device posted error messages and stopped the ventilation.As per report, the device was replaced in a controlled maneuver; no patient consequences have occurred.Remark: dräger has received a user facility report for this incident after having filed the initial report to the authorities.The ufr states that the vent fail led to a delay in surgery which must be considered a serious injury in the meaning of the reporting regulations.Thus, the case has been re-classified from "product problem" to "adverse event and product problem".

Manufacturer Narrative
|
The dispatched engineer from the local dräger s&s organization could confirm the reported aspect of ventilator failure and replaced the entire ventilator unit at the workstation.It was verified by the applicable tests that this has put back the device into fully operable condition.The replaced motor was returned to the manufacturer and subject to an in-depth investigation in the manufacturer's lab.It could be determined that wear-and-tear related abrasion of the collector disc had resulted in development of positions where the motor does not provide mechanic power due to contact interrupts to the carbon brushes; speed fluctuations will be the consequence.The speed fluctuations result in a deviation between measured and expected piston position.The piston hub defines the applied tidal volume and thus, to prevent from potentially hazardous output and/or from damages to the ventilator unit, the system is designed to shut down automatic ventilation and to alert the user to this condition by means of a corresponding alarm.Manual ventilation with the built-in breathing bag including gas dosage remains further possible.Dräger finally concludes that the device behaved as specified upon the malfunction of a single component.The number of similar cases, related to the same root cause, is within the expected range of the respective risk assessment and thus accepted.
