The device was not returned for evaluation; it was discarded at the hospital.Without return of the unit it is not possible to determine if some damage or defect existed on the unit that could have contributed to the event.It is not known if some procedural factors may have contributed to the event.A review of the manufacturing records indicated that the product met specifications upon release.As part of the manufacturing process a 100% of the units go through an electrical inspection process.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 patients clinical manifestations.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.

It was reported that the svr >5000, core temp and cardiac index values were inaccurate.However, the pa pressures and waveforms appeared normal.The mixed venous blood draw on the patient did not correlate with the readings.No patient complications were reported.Patient demographics were unable to be obtained.
