Abstract

A method and apparatus (20) for maintaining a gas in a predetermined pressure range during a gas exchange process. The apparatus (20) includes a first conduit (21) having a gaspermeable membrane wall portion (25), atleast one inlet port (26) for introdusing a first gas into the apparatus, and a reservoir (28) arranged to contain the first gas. The method and apparatus are particularly suitable for oxigenating an extracorporeal flow of blood.
