[Transport of carbon dioxide in membrane oxygenators]

A study has been made of the process of removing carbon dioxide from blood in the MOST-type membrane oxygenators. An expression was obtained for the carbon dioxide flow near the diffusional border layer and its change in the blood with regard to the permeability of the membrane used, the value of the blood flow rate, the value of the geometric parameters of the oxygenator, and the blood parameters. The value of the rated by carbon dioxide volumetric capacity of the blood has been calculated. The results of the numerical analysis of the input equations of the carbon dioxide transport are compared to the experimental data obtained from the medico-biologic testing of the oxygenators.
