It was reported that during use of the device for a cardiopulmonary bypass procedure (cpb), the pumps display would intermittently go blank.The pump was controlled through the central control monitor (ccm).The surgical procedure was completed successfully.There was no delay, no blood loss, nor adverse consequences to the patient.Per clinical review: on (b)(6) 2017, the heart lung machine (hlm) was set up and primed without issue.Shortly after initiation of cpb, the roller pump in the sucker position's local display started flickering.The local display would go blank intermittently, and then come back on, and go back out again.The perfusionist on the procedure opted to use the ccm to visually see the flow of the sucker pump, and to adjust the flow.The local knob control was still in usable form.The roller pump was not changed out during the case, but they exchanged it after the procedure was finished.The incident did not delay the surgical procedure.The was no harm nor blood loss associated with the event.

The reported complaint could not be confirmed.The field service representative (fsr) was unable to duplicate the complaint.He replaced the pump display assembly as a precaution.The unit operated to the manufacturer's specifications.Per data log analysis, on 19-dec-2017 there are no indications of a problem in the log file.It is possible the display blanked without logging anything.Normally this is a small display assembly issue, or a connection to the small display assembly.During laboratory analysis, the product surveillance technician (pst) observed the display assembly to function normally throughout the evaluation with no loss of display.If additional information becomes available on this complaint that would alter the facts and/or conclusion, a supplemental report will be filed accordingly.
