The ufr was the only information for this case; the hospital did not involve the local dräger s&s organization into any follow-up measures.The contact person named in the ufr could not provide further information.The available information is insufficient for an evaluation; the issue cannot be completely understood.Dräger derives the following: a shut-down has occurred due to loss of energy.If so, the device will post a power-loss alarm via a buzzer for at least 2 minutes; this buzzer is powered by an independent power source (goldcap capacitor).The primary energy source for the device is mains supply but the workstation is equipped with an internal battery to cover mains power losses for a certain period of time.A complete shutdown is thus very unlikely to occur in single-fault condition.Mains power may have got lost due to various reasons - due to an infrastrusture issue in the hospital's power supply network, due to use error (incorrectly plugged-in power cord) or to component malfunction in the device-internal power supply.Most likely, the device was put into operation with a worn internal battery - otherwise the device was continuing operation on battery supply.The internal battery is subject to wear and tear, shall be regularly inspected and has a recommended exchange interval of two years.The affected device is more than five years old, and it is not known when the last battery exchange was performed if ever.The ifu emphasizes that availability of the internal battery shall be checked prior to each use cycle.Finally, dräger postulates that failure to follow the instructions of the manufacturer was most likely a contributing factor in the event.It is recommended to have the device checked by authorized service personnel and to have it repaired if necessary; original dräger spare parts shall be used then.
