Patient at the hospital for an aorto-coronary bypass on (b)(6) 2014.During the procedure and while the surgeon was attempting to place the patient on the bypass pump the oxygenator on the heart and lung machine failed to operate correctly.The perfusionist said the device had less than satisfactory oxygen levels.Problem was noticed by perfusionist immediately and informed the surgeon of the problem.The crossclamp had not been applied yet.Anesthesiologist continued to bag the patient.All connections were checked so again the team tried to go on bypass but the oxygen level fell again.Anesthesia continued to bag the patient.An oxygen tank was brought into the room and wall oxygen was bypassed (to rule out an oxygen supply problem) and again the same situation happened.Going on the pump was temporarily suspended while perfusionist changed out the oxygenator.After the oxygenator was replaced and verified that it was working properly the patient was placed on the pump with no problems noted.Patient was discharge on (b)(6) 2014 to his home.Have been in contact with (b)(4) from terumo requesting device for testing.
