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.Thus, dräger is unable to perform an investigation, the reported shut-down can neither be confirmed nor denied.The most likely explanation for a shut-down would be loss of energy supply.Under consideration that this postulation is correct, an occurrence under single-fault condition is unlikely since the device is equipped with an internal battery to cover mains power losses for at least 30 minutes (with a fully charged battery in good condition).But if - for example - the device was put into operation with a completely worn internal battery, a power supply malfunction or a cut-off of mains supply caused by infrastructure issues may have ended-up in a shut-down.Finally, the issue may also have been related to use error - e.G.If the device was not connected to mains power and operated until the battery was depleted.A reliable conclusion is not possible due to lack of information.It is recommended to have the device checked by authorized personnel and to have it repaired if necessary.
