Recirculation is a condition which may occur in venovenous ECMO configuration: in relation to this phenomenon, a variable fraction of the reinfused oxygenated and decarboxylated blood is withdrawn through the drainage cannula. Recirculated blood bypasses systemic circulation without supporting CaO2, so recirculation fraction does not contribute to DO2, lessening the efficacy and the efficiency of extracorporeal respiratory support.
In this video recirculation in femoro-femoral cannulation and in femoral drainage/jugular reinfusion cannula configuration, respectively.
