Considerations for Selecting Double-Lumen Catheters in Adult ECMO

The 53rd Annual Meeting of the Japanese Society for Artificial Organs (Bunkyo-ku, Tokyo, Japan)

Double-lumen catheters are used for circulatory support for respiratory assistance in Western countries. Insufficient flow due to smaller catheter diameters can lead to hypoxia. Therefore, we investigated whether sufficient oxygenation could be achieved. Arterial partial pressure of oxygen (PaO2) 20 minutes after the start of circulation was 28.6±4.5, 62.6±9.3, and 127.9±21.5 mmHg at flow rates of 1, 2, and 3 L/min, respectively. We report that insufficient flow due to size limitations can result in inadequate oxygenation and potentially cause hemolysis due to increased circuit pressure. I was responsible for the study design, data collection and analysis, and abstract and slide preparation. Co-presenters: Togo Y, Takewa Y, Katagiri N, Fuji Y, Miyamoto Y, Tatsumi E.
