It was reported that during use of the device for a cardiopulmonary bypass (cpb) procedure, the level sensor pad popped multiple times.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: during set up, during circulatory arrest and during the rewarming phase of bypass the perfusionist had the level sensor pad disconnect from the reservoir.The first pad she did not wait the five minutes to load the cable.After she replaced the first one with another pad, she did wait the five minutes before placing the sensor on the reservoir.The following two she did not wait the five minutes, for she was on cpb and felt that it was more of an urgent matter to get the level detection system to work.The team was using a fx15 reservoir for this procedure and was only using the alarm cable.She does place her pads on the label of the graduated volumes.I suggested to her to place pads on a non-label portion of the reservoir, and if needed cut the wings of the pad to enable it to stick better on a non-labeled area on the fx15.The team has their heart lung machine (hlm) to just give the perfusionist a notification if the level goes below the set point, therefore this incident did not stop a pump.The incident did not delay the continuation of the surgical procedure.There was no blood loss or harm associated with the event.
