Fig. 7From: A mathematical model of CO2, O2 and N2 exchange during venovenous extracorporeal membrane oxygenationThe effect of recirculation. \( \frac{{\dot{Q}}_S}{{\dot{Q}}_T} \) is held constant at 0.7. With increasing recirculation, PaCO2 rises and SaO2 falls. Recirculation has more effect on PaCO2 when \( {\dot{Q}}_{EC} \) is lowBack to article page
