It was reported that after three days use on patient, the cardiosave intra-aortic balloon pump (iabp) a nurse had noticed the unit had been in standby mode for an unknown period of time and an error message of " system over temperature" was displayed on the monitor.The physician decided to discontinue the iabp therapy since the patients condition had not improved and he was not expected to recover anymore, the patient had devolved ventricular fibrillation which was caused by anesthetic complications after an unknown surgery had been being treated by ecmo.The further treatment with the iabp therapy and pacemaker was required.The patient had expired later on the same day, according to the physician, the possible relationship between the patient's death and this issue and this iabp unit is low due to a poor outcome.This iabp was setting with maximum augmentation level and iab frequency of 1:1 by ecg trigger in auto operation mode.The trigger was lost occasionally.After iabp therapy ended, running test was performed with the internal trigger by a medical engineer of this facility until the morning of the following day; however the issue was unable to be replicated.
