    background and purpose
    In vitro circulation (CPB) is designed to provide oxygen (?) The right balance is maintained between O2) and oxygen consumptionCritical? O2means that oxygen consumption depends on oxygen supply at a certain amount of oxygen supplyThe purpose of this study is to determine the criticality of newborns with higher metabolic rates than adults? O2calculated according to the CPB parameters recorded during aortic blocking in this retrospective neonatal cohort study? O2The high lactic acid concentration (lactOFF) measured after the aorta is opened is used to identify anaerobic metabolismData analysis uses a hybrid linear proportional regression modelIn the lactOFF 2.5 mM subgroup (these children are thought to be in balance between oxygen supply and oxygen consumption), analysis? The relationship between theo 2 and temperature Estimated regression coefficients are further used to adjust assumptions? O 2 threshold and will it fall below the threshold? O 2 offset squanited as strength duration At 37 degrees C, the minimum threshold for providing strength duration is associated with an increase in lactOFF and is used as the minimum suitability (critical)? O 2 Results 22,896 points in 180 newborns were analyzed in this study 40 cases 2.5mM of children, ? O 2 changed 22.87 (0.70) ml -1 m -2 -c -1 change between 340-380ml min -1 m -2 ?

The offset of 100 ml m -2 of the O 2 threshold increases the risk of increasing the lactOFF by 22% (OR: 1.22; 95% CI: 1.02 to 1.45) by increasing the risk of 1 mM in the lactOFF The results of the found that 340 ml of -1 m -2 may be the minimum suitable (critical)) required for newborns to maintain aerobic metabolism during the normal temperature CPB?
