Recirculation During Veno-Venous Extra-Corporeal Membrane Oxygenation – A Simulation Study

Speaking of Simulation – it is also useful in the investigation of situations that are not easily defined in patients.

Veno-venous ECMO is indicated in reversible life-threatening respiratory failure without life-threatening circulatory failure. Recirculation of oxygenated blood in the ECMO circuit decreases efficiency of patient oxygen delivery but is difficult to measure. We seek to identify and quantify some of the factors responsible for recirculation in a simulation model and compare with clinical data.
