Abstract

The invention relates to an arrangement (10, 100, 200) for removing carbon dioxide from an extracorporeal flow of blood. The arrangement (10, 100, 200) comprises a filter (12) which has a membrane (16) that separates a blood region (14) from a gas region (18). The extracorporeal flow of blood is passed through the blood region (14) of the filter (12). Likewise, a gas flow of a purge gas is passed through the gas region (18), the purge gas being an inert gas or a mixture of inert gases. Further, the invention relates to a method for removing carbon dioxide from an extracorporeal flow of blood in which likewise an inert gas or a mixture of inert gases is used as a purge gas.
