It was reported that during intra-aortic balloon (iab) therapy, the console generated a catheter restriction alarm.Intensive care unit staff were unable to troubleshooting the alarm.The physician arrived two hours later and removed the catheter.The catheter was kinked which caused the console to alarm catheter restriction.After the iabp therapy, the console was tested with a different catheter and the device functioned without generating a restriction alarm.The original catheter was tested again and it put the device into a catheter restriction alarm.The balloon pump passed all performance testing and was put back into service.There was no reported injury to the patient.
