Findings: the involved 50328-07 catheter was not returned for analysis and confirmation.The triox catheter is a precision optical instrument and must be handled with care.Kinking, excessive manipulation, or grasping with forceps or hemostats can permanently damage the fiberoptics, reducing the transmission of light to and from the blood.Care should also be taken to remove any slack or loops in the catheter as this can also lead to migration.The 50328-07 catheter was pre-tested prior to placement with no issues detected at that time.The exact cause(s) of the reported event/product issue are unknown.Device not returned.
