Apparatus for supplying breathing fluid to an internal combustion engine or the like. A lung humidifies oxygen from a source of oxygen such as H2O2 and a catalyst pack or gaseous or liquid oxygen to a mixture of oxygen to the engine. Means, such as a container of caustic solution and water vapor is provided so that the exhaust products from the engine, which includes gaseous oxygen, water vapor and carbon dioxide, are separated. The CO2 is absorbed in the caustic solution and the O2 is recirculated to the lung after it is combined with additional O2.
