AN EVALUATION of the disposable bubble oxygenator (Travenol U-310) has been done under controlled conditions to determine the circumstances under which optimum performance might be expected and to define the margin of safety which this oxygenator affords. Blood of any desired gas composition was obtained by recirculation through a stationary screen oxygenator (Mayo-Gibbon) using various gas mixtures in the chamber. The blood was then passed a single time through the bubble oxygenator and changes in a particular parameter measured. Three parameters have been studied: (1) the effect of varying the gas flow rate to the oxygenator, (2) the effect of blood flow on the ability of the oxygenator to oxygenate blood, and (3) the ability of the oxygenator to remove carbon dioxide.
Preliminary to the experimental determination, it was necessary to have information on the efficiency of the screen (control) oxygenator. In these experiments efficiency was defined in
