The production device history record (dhr) for this intra-aortic balloon pump (iabp) was not required to be reviewed per getinge standard operating procedure since the device manufacture date is greater than one year from the event date.A getinge field service engineer (fse) was dispatched to investigate.The fse evaluated the iabp unit and was unable to duplicate the complaint of the ecg waveform disappearing.The ecg waveform continuously displayed while using the trainer as well as the minisism simulator.The voltage for the ecg was checked and was within specs.The only issue the fse discovered was that the resistance on the customer's ecg cable was significantly higher than the new ones the fse has.It was recommended that the customer replace the ecg cable.In addition, the fse was unable to duplicate the "pump stopping" problem but noticed different triggers used on the date of the reported event.The fse replaced the blood detect tubing which broke while performing the blood detect test.Gasket retrofit and software update field action were also completed at the same time during this repair.The iabp unit was tested for functionality, performance and safety are all within specs.The unit was released for medical use.The facility's representative was not available at the time the evaluation was completed.The fse separated the ecg cable from the iabp unit and handed it over to the nurse at the front desk, with a note on the unit stating that the cs300 tested ok, but the ecg cable needed replacement.
