ABSTRACT:
A chemical oxygen device having one or more CO.sub.2 -bonding and O.sub.2 -releasing chemical canisters (2) arranged in a housing (1); a breathing bag (3) for the exhaled air, which itself is arranged in a breathing bag (7) for the inhaled air; an inhalation valve (4); an exhalation valve (5); and a particle filter (6). The usage conditions of chemical oxygen devices is improved by reducing breathing resistances and by an indication of consumption indication in which, at any time, the supply of breathing gas still available is indicated. A bellows (8) is arranged between the breathing bag (3) and chemical canisters (2) to reduce the breathing resistances and the particle filter (6) is arranged at the input of the breathing bag (7). The bellows (8) is connected to an evaluation unit (9), via which the wearer of the chemical oxygen device can check at any time the supply of breathing gas still available.
