Abstract

We developed a new membrane oxygenator (PS-AL) which consists of microporous polysulfone hollow fibers, 205μ in inner diameter and 293μ in outer diameter.
The surface area available for gas exchange was 1.1m². Gas exchange performance was obtained in vitro and in animal experimental studies. Oxygen gas transfer rate was 95.6±3.83mL/min/m² and carbon dioxide gas transfer rate was 63.7mL/min/m² (QB 1500mL/min, Gas Flow Ratio 1.0).
