Abstract
From 1976 to 1977, Kolobow membrane oxygenator were clinically applied to 600 patients at the time open heart surgery.
Effect of compressed air and N20 gas on blood gas change during E. C. C. were studied, In relatively small Kolobow membrane oxygenator (0.8M2 or 1.5M2) addition of either compressed air or N2O gas to oxygen has proven to be quite useful in maintaining arterial PO2 and PCO2 within adequate range.
