METHOD AND DEVICE FOR SEPARATING OFF CARBON DIOXIDE FROM A GAS MIXTURE Abstract A method is proposed for separating off carbon dioxide from a gas mixture (1 Oa - 1 Oe), in particular from breathing air, with a life-sustaining device, wherein in a first method step (1 2a) the gas mixture (1 Oa - 1 Oe) is fed to an adsorption and/or absorption unit (1 4a 14e) under at least one first pressure, and in a second method step (1 6a) a gas mixture (1 8a - 18e) is conveyed out of the adsorption and/or absorption unit under at least one second pressure that is higher than the first pressure. 10 a 30a P1 vi X "~*Vl 42a---- ---64 14a-- a 10a 108a --O------ 3818a P3~~Fg V56aPI
