Abstract
A gas exchange membrane is for use in an artificial lung. The membrane consists of a foamed, closed-cell material, in particular of silicone rubber. The membrane is produced by extruding a basic material which contains a foaming agent. The extrudate is then foamed. The result is a gas exchange membrane which has an increased gas exchange performance compared to known material due to the high permeability of the surface.
