Abstract
Mortensen (1987) suggested the use of an Intravenacaval Blood Gas Exchange Device (IVCBGE) for assisting the acute respiratory failure, and the membrane lung inserted in the superior vena cava enables to perform the gas exchange as a cross-flow blood oxygenator. The woven tubes membrane oxygenator can potentially suit this method and we have been investigating the oxygen transfer performance of cross-flow woven tubes oxygenator in order to see the feasibility of woven tubes used for IVCBGE. The gas transfer performance in blood turns out to be sufficiently improved to meet the requirement of IVCBGE.
