Figure 2 . Schematic of CPB circuit with standard active ultrafiltration head incorporated . Blood can be sourced from the venous line for prebypass , conventional , and modified venoarterial ultrafiltration . This option exists on all circuit sizes .
temporizing measures exist , which may prove useful during patient care . We believe that our most recent experience with oxygenator failure included a well-timed and appropriate intervention that prevented both patient hypoxemia and circulatory arrest , as evidenced by the nadir SvO 2 , bilateral cerebral NIRS , and indexed oxygen delivery values . Gene Kranz , NASA Flight Director for the Apollo 13 Moon landing mission , is credited with the statement that , “ Failure is not an option .” For cardiac operating room teams , failure of an oxygenator bundle will happen , but failure to intervene appropriately must not occur .
Conclusion
Figure 3 . Picture of a Terumo CAPIOX FX-05 oxygenator with a neonatal / infant 3 / 16 00 arterial limb by 1 = 4 00 venous limb circuit , with a stopcock on the lured venous line connection for the active ultrafiltration circuit . Note that the post-hemoconcentrator line returns to the cardiotomy reservoir for pre-bypass and conventional ultrafiltration ( not shown in the image ).
Oxygenator failure is a high-risk , low-frequency event that perfusion teams must be prepared to handle . An oxygenator change-out procedure has long been considered the standard intervention , with or without cessation of cardiopulmonary support , depending on surgical progress and a team ’ s standard bypass circuit configuration ( i . e ., the inclusion of a PRONTO option ). We have modified our clinical practice to include an intervention algorithm for confirmed oxygenator device failure .
