The customer reported: patient was put on intra-aortic balloon pump (iabp) therapy due to weak heart circulation after having aorto-coronary bypass surgery and aortic valve replacement.
During iabp therapy, the iabp generated an "air leakage" alarm ("gas loss in iab circuit").
Along with the alarm, a solid white line/"white balk" appeared on the display.
The caregivers checked the iab with a syringe to make sure that was no blood or leaks inside the iab tubing.
The caregivers also verified the iab position with x-ray and checked there were no blood clots by transesophageal echocardiography (tee).
The patient¿s health status deteriorated and the caregivers made the decision to stop therapy.
Shortly after the discontinuation of therapy, the patient died.
The patient death per the caregivers, was not attributed to the iabp.
