It was reported that during use of the device for a cardiopulmonary bypass (cpb) procedure, the heater cooler made a loud noise and stopped pumping at the end of the case.An 'pump not primed' alarm was displayed when the main pump was started.As a result, an alternate device was employed.The surgical procedure was completed successfully.There was no delay, no blood loss, nor adverse consequences to the patient.Per clinical review: the perfusion team had an incident regarding the heater cooler device.Towards the end of the cpb procedure, the perfusionist (ccp) heard a loud noise from the heater cooler and then it stopped pumping water to the heat exchanger/oxygenator.He attempted to start the main water pump again, and the 'pump not primed' error message occurred.The patient was warm at that point, but to maintain the appropriate warm temperature, the perfusionist made the decision to change out the unit to another unit.This changing of the equipment did not delay the surgical procedure.The patient was weaned from cpb without issue, and there was no blood loss.No harm was observed.
