Oxygenation performance of the IVC → RA and IVC + SVC → RA routes. Beyond QEC/Qc = 1 using the IVC+SVC → RA route, QEff reaches the Qc value and cannot increase further. QEC increases then due to structural recirculation. IVC inferior vena cava, PULM-Shunt pulmonary shunt, QEC extracorporeal pump flow, QEff effective extracorporeal pump flow, QC cardiac output, RA right atrium, SaO2 arterial blood oxygen saturation, SPAO2 pulmonary arterial blood oxygen saturation, “SvO2” mixed venous blood oxygen saturation, SVC superior vena cava
