It was reported that although arterial blood pressure was observed for a brief second, it gradually moved down and eventually became unable to be observed on the first day of use.The catheter and the pressure monitoring set were replaced, and the problem was solved.Both devices were used with the same patient.There was no abnormal waveform observed.The dpt was zeroed before use.The data logs were not provided.There was no occlusion, leakage or kink noted.The patient was not treated based on the incorrect value.The patient demographic information was requested but unavailable.There were no patient complications reported.

One ts105f5 catheter with bd 1 cc syringe was received for evaluation.The reported pressure measurement issue was not able to be confirmed from the evaluation.All through lumens were patent without any leakage or occlusion.There was no visible damage or inconsistency observed from catheter body, balloon and returned syringe.The balloon inflated clear, concentric and remained inflated for more than five minutes without leakage.This sample was then transferred to the irvine lab for further evaluation.The catheter passed the pressure test with the returned dpt.The pressure reading was stable during the 8 hour long output drift test.Per edwards pressure monitoring ifu, "poor dynamic response can be caused by air bubbles, clotting, excessive lengths of tubing, excessively complaint pressure tubing, small bore tubing, loose connections, or leaks." the reported event could not be confirmed or replicated during the analysis, as the device responded appropriately during functional testing.It is not known if some procedural factors may have contributed to the event.Although no fault was found, an investigation has been initiated to consider any potential manufacturing factors that may have contributed to this complaint.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.
