Mass Transfer Modelling for Membrane Oxygenators
Theoretical analysis of O2 and CO2 transfer in membrane lung channels with streamline flow has been sufficiently developed to adequately predict experimental results. These methods are of great utility both for data interpretation, since generalised coordinates are used, and determining either deficiencies or benefits of a particular membrane lung design. Total bypass units, of necessity, must contain large permeable membrane surface areas unless a technique to augment respiratory gas transfer is employed. The verification and advantages of theoretical methods will be considered along with their extension to geometries which use secondary flows to increase the efficiency of O2 and CO2 exchange.
