Event Description

The customer contacted physio-control to report that their device displayed ¿abnormal energy delivery¿ during testing.There was no patient use associated with the reported event.Upon evaluation of the device, physio-control observed that the device had a partial loss of defibrillator output energy due to a loss of the negative portion of the biphasic output waveform.The defibrillator output energy could be reduced by up to approximately 20% from the selected energy level.
