Manufacturer Narrative

The sample was returned for evaluation.A review of the device history record revealed no manufacturing anomalies.The returned sample consisted of only the oxygenator, with the arterial thermistor.Visual inspection of the returned sample found no anomalies, specifically around the thermistor.The unit was setup in a circuit and water was circulated through the unit.The temperature of the water from the water supply was measured as well as the temperature of the fluid at the oxygenator's thermistor.The temperatures of the fluid at both locations matched exactly.The reported event was not able to be replicated and the complaint was not confirmed.If temperatures are taken at two separate locations and then compared, the variability in the fluid may cause the temperatures to truly be different at these different locations.The temperature at the venous thermistor is likely to vary from the temperature at the arterial thermistor, especially due to the fluid going through the heat exchanger between these two locations.If temperatures are read at a time that the fluid is being warmed or cooled, and a steady state temperature is not achieved prior to measuring this temperature, this will also cause a difference in readings.All available information has been placed on file in quality management for appropriate tracking, trending and follow up.
