The following description of the event was documented by a carefusion technical support specialist in response to a phone conversation with a user of our device: "flowsensor calibration problem.Getting warning that marginal correction factor is out of range (1.95-2.00) he just installed this flowsensor lot number be0311.Asked him to inspect the cal syringe hose for ters or holes.He says there are tears in the hose.Asked him to change it out, he will use another 32 liter syringe and hose from another system and try calibration again." customer was concerned that once he recognized that the correction factors were out of range that he would require retesting of previously tested patients.
