It was reported that the ventilator was working normally at 12:30, a respiratory alarm occurred at 12:40, the respiration was not in working condition, and after restarting it was still not working properly, manual support respiration was given, and there were no reports of patient injury.Based on the initial confirmation, no report was received that the ventilator did not work, so a field engineer was dispatched to the site to verify the event and download the equipment logs for further analysis.The manufacture analyzed the logs obtained and according to the log files, the device failed on (b)(6) 2023,but the event was not consistent with what was reported to the hospital in adr.The actual malfunction was an error report of a negative ventilator roll film pressure below specification, which was resolved by adjusting the position of the 2600650 component, and no similar problems have occurred to date.This phenomenon is mainly caused by the 2600650 component not being installed correctly after cleaning and disinfecting, i.E., the probable cause is user error.It can be confirmed that the hospital's adr report that ventilator did not work was inaccurately.
