It was reported that upon insertion of a sensation plus intra-aortic balloon (iab), the cardiosave intra-aortic balloon pump (iabp) displayed an altered waveform and would not calibrate.A false cyclical/ spiked artifact displayed throughout the fiber-optic arterial pressure waveform with no alarm.The balloon was left in and the staff used the fluid lumen as an alternate arterial lumen.There were no effects to the patient.The patient was being transported to another facility; therefore, the staff did not attempt to arrange for return of the iab.No adverse event was reported.
