It was reported that during use of the device for a cardiopulmonary bypass procedure, the perfusionist (ccp) received a belt slip error on the roller pump.The surgical procedure was completed successfully.There was no delay, no blood loss, nor adverse consequences to the patient.Per clinical review: per email communication with the perfusionist (ccp), the ccp reported during cardioplegia delivery (4:1 set), an alarm with message occurred (beltslip) and the ccp claims the cardioplegia pump stopped.She simply re-started the pump in a few seconds and no other issues occured.I sent her the attached email to inform her of messages that can occur when the pump is overoccluded (beltslip for example) and new 1.40 software is installed.She was not aware of this potential behavior, with 1.40 software pumps.She now knows, that roller occlusion may need to be adjusted if messaging (like beltslip) occurs in the future.This pump continues to be used and has been used in other cases, since this event.The case was completed successfully, without delay and without associated blood loss.There was no harm observed.

The field service representative (fsr) was dispatched to the user facility.The fsr tried duplicating a belt slip using 1/4" and 3/8" tubing, but did not receive a belt slip error.In using the pump jam preventive maintenance (pm) fixture the fsr could get a pump jam message as normal but not reproduce the belt slip error message.The fsr completed the pm on the device and the device operated to the manufacturer's specification.If additional information becomes available on this complaint that would alter the facts and/or conclusion, a supplemental report will be filed accordingly.
