Customer stated that a sc80 sensor cassette on the abl80 flex analyzer failed and generated a low po2 value on a patient sample after the physician placed the patient on oxygen.The reported po2 value was approximately 270 mmgh.The physician questioned the result and reran the sample on the abl800 analyzer, which generated a po2 result of approximately 400mmhg.There was no reported injury, diagnosis or treatment based on the low po2 result.(b)(4).

Evaluation of the failed sensor cassette is currently in progress.However, sendx medical did evaluate the data logs form the failed sensor cassette.It was discovered that the po2 parameter failed manual qc and the customer did not follow the manufacturer's recommendations for such failures (ie follow the analyzer instructions on the screen or the recommendations in the operator's manual).Instead, the customer ignored the failure and ran a patient sample.Incidentally, the analyzer generated a low po2 result on the patient sample.However, it should be noted that the analyzer performed according to specifications and notified the user that manual qc failed for po2, whereby the customer should not have run a patient sample on the sensor cassette without first resolving the manual qc failure.
