Two 831f75p catheters from the same lot number, in sealed packaging, were returned for examination.The customer stated he wanted both of them looked at due to loss of confidence.The reported issue of central venous pressure (cvp) and the pulmonary artery pressure (pap) readings being in reverse, was unable to be confirmed.As received, the catheter was found to be correctly identified and assembled.All through lumens were patent without any leakage or occlusion.A 10cc syringe was connected to each of the lumens being tested.Each associated port was covered with a fingertip, entire catheter was immersed in water and pressurized with air by compressing the syringe plunger.The balloon inflated with the returned syringe and immersed in water to check leakage.The balloon inflated clear and concentric inflated for five minutes.All through lumens passed the pressure test.A device history record review was completed and documented that device met all specifications upon distribution.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.
