Additional Manufacturer Narrative
A1: patient identifier: requested, unknown.A2: date of birth: requested, unknown.A4: weight: requested, unknown.A5: ethnicity: requested, unknown.A6: race: requested, unknown.D6a: implanted date: device was not implanted.D6b: explanted date: device was not explanted.E1: telephone number: requested, unknown.Visual inspection of the actual sample upon receipt found there was no anomaly such as a breakage.The actual sample, after rinsed and dried, was tested for the o2 transfer and co2 removal performance in accordance with the product inspection protocol.The test result shown below met the factory's control standards.No anomaly was found.[bovine blood conditions] hb: 12 g/dl, temp.: 37°c., ph: 7.4, svo2: 65%, pvco2: 45 mmhg; [circulation conditions] blood flow rate: 6 l/min and 4 l/min, v/q:1, fio2: 100%; [o2 transfer volume] @6 l/min: 383 ml/min., @4 l/min: 274 ml/min; [co2 removal volume] @6 l/min: 306 ml/min., @4 l/min: 218 ml/min.Review of the manufacturing record and the shipping inspection record of the actual sample found no anomaly.A search of the past complaint file regarding the involved product code found another similar complaint was received from the same facility.Based on the investigation result, the gas transfer performance of the rinsed actual sample met the factory's control standards, and no anomaly was found in the manufacturing records.The cause of occurrence in this case could not be clarified due to lack of detailed information.Relevant instructions for use (ifu) reference: "start gas supply with v/q=1, and fio2=100%, then make adjustments based on blood gas measurements." "measure blood gases and make necessary adjustments as follows." a.Control pao2 by changing concentration of oxygen in ventilating gas using gas blender.To decrease pao2, decrease[?]fio2.To increase pao2, increase fio2.B.Control paco2 by changing the total gas flow.To decrease paco2, increase total gas flow.To increase paco2, decrease total gas flow." "upon patient rewarming, adjust o2 concentration, gas flow rate and blood flow rate by increasing them as needed based on an increasing in patients metabolism.Failure to adjust the gas supply and the blood flow rate appropriately may cause insufficient o2 supply needed or the amount of the patient's gaseous metabolism." "a phenomenon called wet lung may occur when water condensation occurs inside fibers of microporous membrane oxygenators with blood flowing exterior to the fibers.This may occur when oxygenators are used for a longer period of time.If water condensation and/or a decrease in pao2 and/or an increase in paco2 is noted during extended oxygenator use, briefly increasing the gas flow rate may improve the performance.Increase gas flow rate, to 20 l/min for 10 seconds.Do not repeat this flushing technique, even if oxygenator performance is not improved." terumo medical products (tmp) (importer) registration no.2243441 is submitting this report on behalf of ashitaka factory of terumo corporation (manufacturer) registration no.9681834.
Event or Problem Description
The user facility reported that poor oxygenation occurred after 215 minutes cardiopulmonary bypass (cpb).The oxygenator was replaced.Cpb total time was 450 minutes.There was no patient injury/medical or surgical intervention required.The procedure outcome was not reported.The final patient impact was not harmed.
