The use of microporous membranes of hydrophobic polymers such as polypropylene have been widely applied to the membrane oxygenator. Carbon dioxide transfer, which is fairly sensitive to gas permeability of the membrane, becomes deteriorated due to the liquid entering into the pore. In this study, the carbon dioxide transfer in the microporous membrane oxygenator was experimentally evaluated to clarify the effect of membrane resistance. The membrane resistance of microporous polypropylene is negligible in a water test but increases in contact with blood. The membrane resistance remains 30% of the blood-phase resistance for the blood path pressure below 27kPa. For higher blood-phase pressure, carbon dioxide transfer is largely deteriorated.
