ABSTRACT:
The oxygenation and removal of carbon dioxide from blood by simultaneous mass transfer through a microporous membrane is improved by pulsing the flow of oxygenating gas over the membrane. This avoids the progressive reduction in carbon dioxide transfer rate which otherwise occurs with steady gas flow and allows such transfer rate to be maintained at an acceptable level.
