Impact of bypass flow rate and catheter position in veno-venous extracorporeal membrane oxygenation on gas exchange in vivo

The 54th Annual Meeting of the Japanese Society for Artificial Organs (JSAO), Yonago, Tottori, Japan

We investigated the optimal return cannula placement site, focusing on gas exchange, for circulatory support intended for respiratory assistance. We demonstrated that oxygenation and carbon dioxide removal were optimal when blood was drained from the inferior vena cava (IVC) and returned to the superior vena cava (SVC), thereby identifying the SVC as the optimal return cannula placement site from a gas exchange perspective. We presented orally that the optimal sites for the return and drainage cannulae for circulatory support, from the perspective of oxygenation and carbon dioxide removal, are the SVC and IVC, respectively. I was responsible for the study design, data collection and analysis, and abstract and slide preparation.
