Recirculation quantified by Trans-ECMO thermodilution to predict mixed venous oxygenation during V-V ECMO: an in vivo porcine study

TET is a promising technique to measure the recirculation during V-V ECMO. Increasing the blood flow does not always lead to an improvement in oxygenation given the tight relationship between ECSF and recirculation. The proposed numerical method allows the non-invasive estimation of the mixed venous oxygenation without the need of a pulmonary artery catheter.
