According to the support case#(b)(4) and the service protocol (order no#(b)(4)) date on (b)(6) 2019 the technician performed as follows: the technician tested the pump in each of the modes and it works correctly.No safety or function defects detected.Verified the bubble sensor and detected a damaged cable (fracture near the head of the cable) which caused the problem.The customer will buy a new sensor and the machine is out of clinical use until they get the new one.Thus the reported failure could be confirmed.A similar case (sap#(b)(4)) was already investigated by the supplier em-tec.According to the e-mail received from the supplier the most probable root cause for the broken cable is too high mechanical stress (cable was bend too often), which finally led to a fracture of the cable.Since this is a user error, no remedial action is required.The occurrence rate of this error is below the acceptable rate.The occurrence rate related to the reported issue is currently being monitored as part of maquet cardiopumonary¿s trending program and additional investigations or corrections will be implemented in case of adverse trending.
