Event Description
|
It was reported that during patient use in the cvicu, using a swan ganz catheter, there were erratic patient measurements of the core temperature, while connected to the hemosphere monitor.The issue would temporarily resolve if the cco cable was unplugged from the catheter and then plugged back in.However, the temperature would begin drifting to abnormally high values.Reported as high as 115 degrees f, leading to the cessation of cco readings.The clinicians reportedly ran a successful cco cable test on the cable involved.The issue still occurred when using a replacement cable as well.The catheter had reportedly been indwelling for three days prior to this issue.A new catheter was not inserted.The exact event date is unknown.The catheter was not saved for return.There was no inappropriate patient treatment reported.The patient demographics have not been provided.There was no patient harm or injury.

Manufacturer Narrative

It was previously reported in error that the product was discarded and unable to be evaluated.Our product evaluation lab received one model 777f8 catheter with a non edwards contamination shield.When connected to the lab hemosphere monitor, no fault readings were noted.The thermistor read 37.0 degrees celsius when submerged in a 37.0 degrees celsius water bath.The thermistor reading was within specified accuracy, per the hemosphere manual.The catheter ran continuous cardiac output in a 37.0 degrees celsius water bath for 5 minutes with no error.The thermistor and thermal filament circuits were continuous with no open or intermittent conditions.No visible inconsistencies were observed on eeprom data.The resistance value of the thermal filament circuit was measured within specification at 37.07ohms.Both the thermistor and thermal filament connectors were opened, and no visible inconsistencies were found.All through lumens were patent without any leakage or occlusion.The balloon inflated clear and concentric, and remained inflated for more than 5 minutes without leakage.No damage or inconsistency was observed from the catheter body, balloon, or the returned syringe.The customer report of erratic measurements of core temperature and no cardiac output reading were unable to be confirmed on evaluation.A device history record review and an engineering evaluation have been ordered to assess for any manufacturing-related processes which could be correlated to the complaint.A supplemental report will be sent with the investigation results, as indicated.
