"A preliminary study was done to determine the feasibility of using a compressed fibrous teflon (PTFE) silicone polymer membrane in extracorporeal oxygenation devices. A series of composite membranes were fabricated, using different concentrations of a dimethyl silicone polymer dissolved in petroleum ether, to give membranes having variable oxygen transfer properties. A gas-gas system was chosen to obtain the necessary transfer data. Data were obtained by transferring pure oxygen through the membranes into a mixture of 47 mole percent oxygen and 53 mole percent carbon dioxide. All analyses were obtained by chromatographic techniques. The results of these experiments show that membranes can be fabricated having a wide range of oxygen capabilities. The oxygen transfer coefficients, when translated to blood-oxygen data, indicate that these composite membranes may be feasible for use in oxygenator devices. This type of membrane has the desirable feature of using thin silicone membranes which are self supporting"--Abstract, page iii.
