Without the return of the product, it is not possible to determine if damages or defects exist on the product, nor can any manufacturing nonconformance, failure mode, root cause, or potential contributing factors be identified.It is unknown whether user or procedural factors contributed to the stated event.No lot numbers were not provided; therefore, a review of the manufacturing records could not be completed.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, values can change quickly and dramatically.If the displayed values do not correlate to the clinician¿s satisfaction, it is common clinical practice to the abort the attempt to obtain cardiac output.The catheter can be exchanged if desired.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 to the edwards field specialist that nurses have been having recurring issues with the swan-ganz catheters providing inaccurate cardiac output values when shooting a cardiac bolus.They described that they don't feel any resistance when shooting the bolus and the numbers often don't make sense.The customer switched from a non-edwards brand monitor to philips monitors approximately a year ago.The hospital has conducted training and observation to ensure the issue is not user error related.No other changes have been noted that could be causing this issue.The dates of occurrence, model and lot numbers, and specific details are unknown.There is no allegation of any patient injury associated to the events.All devices were discarded.
