The gas exchange chamber has a blood flow channel extending through the gas exchanger defined by a microporous membrane forming a wall separating the blood flow channel from an oxygen, carbon dioxide exchange media. A second membrane supported in spaced-apart relationship from said first membrane. The space between the membranes is filled with the oxygen carbon dioxide exchange media.
