Silicone rubber has found wide application of membrane oxygenator on the high gas transfer properties. Pure silicone rubber has a rather low tensile strength which must be increased by the additional of filler materials, silica, in order to be utilized. The new coil membrane oxygenator has conposited of membranes which the oxygen layer consists of standard silicone rubber and the blood contacting layer consists of filler-free silicone rubber. This membrane well suited for use in a new coil membrane oxygenator, and this study was undertaken to evaluate the O2 and CO2 transfer of a new oxygenator.
