The respirator comprises a first oxygen-liberating chemical cartridge housing which has a first end with a first opening and an opposite end with a second opening. The first cartridge has a tubular extension adjacent the second end communicating with the second opening and having a lateral air bag opening which opens into an air bag which surrounds the first cartridge. A breathing hose is connected from a mouthpiece which is adapted to be worn by a patient to the first opening of the first cartridge housing. The first cartridge housing also has a breathing tube connected to the second opening of the first cartridge housing and it may be coupled to a similar second breathing tube portion of a second cartridge housing. In addition, the second cartridge housing may be coupled to the air bag or the extension of the first cartridge housing so as to form an airtight seal therewith.
