A device history record review was completed and documented that the device met all specifications upon distribution.Without the return of the product, it is not possible to determine if damages or defects existed on the product, nor can a root cause or any potential contributing factors be identified.No actions will be taken at this time.An engineering evaluation has been initiated to assess for any manufacturing-related processes which could be correlated to the complaint.Invasive procedures involve some patient risks.Although serious complications are relatively uncommon, the physician is advised, before deciding to insert or use the catheter, to consider the potential benefits in relation to the possible complications.The techniques for insertion, methods of using the catheter to obtain patient data information, and the occurrence of complications are well described in the literature.With any hemodynamic monitoring, pressure readings can change quickly and dramatically.Pressure tubing that is used with swan ganz catheters can also be a contributing factor to inaccurate values.In regards to the pressure tubing used with swan ganz catheters, it should be noted that poor dynamic response can be caused by air bubbles, clotting, excessive lengths of tubing, excessively compliant pressure tubing, small bore tubing, loose connections, or leaks.Pressure readings should correlate with the patient¿s clinical manifestations.It is unknown whether user or procedural factors contributed to the stated event.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.(b)(4).

It was reported that during use, a swan-ganz catheter kept reading high pulmonary artery pressure (pap), despite replacing the cable and constantly zeroing.The displayed values were not provided.There was no patient injury.The catheter will not be returned due to contamination.Patient demographics were requested and not provided.
