Getinge usa sales, llc (importer) is submitting this report on behalf of maquet critical care ab (manufacturer).Ref.Exemption #: e2018003 getinge usa sales, llc (b)(4).Contact person: (b)(6).No fault was found when the device was examined at the hospital.There are no technical errors/alarms in the received device logs.System check out passed prior to and after the event.The trend log contains no data since the logs were saved more than 24 hours after the event.The internal log shows that the patient was ventilated without having any sevoflurane added to the fresh gas.The vaporizer was either set to off (in manual ventilation) or no target value was selected in agc.Apart from this, there is nothing else that would explain the reported lack of agent delivery.If the vaporizer would have been shut down by itself or by the system, alarms/technical errors would have been generated.Our conclusion based on the device log evaluation and the received information is that the reported event, that the anesthesia system didn¿t deliver sevoflurane, is related to the user and not a technical failure in the anesthesia system.
