SUBSTANCE: invention relates to medical equipment. A respiratory apparatus represents a device comprising a mask providing a user with both nasal, and oral breathing. A mask through a detached connection is coupled with an air pipe length of which may vary depending on a required load level. An opposite end of the air pipe through the detached connection is coupled with a supplementary respiratory cavity which represents a container with two holes. The first hole is formed in an upper part of the container; it serves for atmospheric air intake by the apparatus. The second hole is formed in a lower part of the container; it serves for disposal of the prepared respiratory mixture into the air pipe. Exhaled and inhaled atmospheric air is mixed in the container. When mixed, they form an air respiratory mixture with higher carbon concentration and lower oxygen concentration.

EFFECT: in breathing, the respiratory mixture supplies an extra amount of carbon dioxide into the body.
