Manufacturer Narrative

The device is not under a service contract.The customer submitted log files and was seeking dräger's assistance.Review of the log entries revealed that the device passed the power-on self test in the morning of the doe without deviations.It could further be revealed that the concerned procedure went stable and unremarkable for the first 30 minutes until the supervisor function of the software detected a drop in the auxiliary vacuum pressure and responded to that with the corresponding alarm reinstall ventilator.The user switched forth and back between certain different ventilation modes but this did not remedy the issue; the device was finally set to standby then.The auxiliary vacuum pressure is needed to keep the ventilator piston diaphragm in place to avoid wrinkling and to prevent from damages to the ventilator unit.The drop in vacuum pressure may be related to certain different conditions.Since it is known that a preventive maintenance ingress was made by inhouse personnel before, it is seen likely that the lower piston diaphragm was incorrectly installed during the maintenance and became punctured during the first half hour of ventilator operation which led to loss of vacuum pressure then.Other than reported the automatic ventilation did not stop but was significantly impaired.Dräger provided feedback to the customer with an instruction what to check to identify the root cause.No response was received.Finally, dräger concludes that the device responded as designed upon the drop in vacuum pressure and posted the corresponding alarm.
