Sorin group (b)(4) manufactures the d 100 ph.I.S.I.O.Hollow fiber oxygenator.The incident occurred in (b)(6).(b)(4).The device was not made available for investigation by the customer.However, the blood flow and oxygen flow data recorded by the customer during the procedure were provided, which indicated that the optimal gas/blood flow ratio described in the instructions for use (ifu) was not achieved, while maximum blood flow rate was exceeded.This may be the cause of oxygenator poor gas exchange.Without the ability to investigate the device, a device failure could not be confirmed and a root cause could not be determined.A review of the dhr did not identify any deviations or non-conformities relevant to the reported issue.
