Abstract
Blood flow disturbance of veno-venous extracorporeal membrane oxygenation (VV-ECMO) can be a risk factor of weaning failure. We report an alternative position of cannulae of VV-ECMO which can maintain blood flow. The recirculation rate could be controlled by adjusting a position of return cannula using dilutional ultrasound monitoring.
