An apparatus for forming precise and regulated mixture percentages of oxygen in a breathing gas, comprising: (a) means for supplying a stream of hydrogen carrier gas; (b) means for injecting the oxygen into the hydrogen carrier gas at a flow rate substantially lower than the flow rate of the stream of carrier gas to form the breathing gas, and with the percentage of oxygen in the hydrogen carrier gas being five percent or less; (c) conduit means for circulating the stream of hydrogen carrier gas and injected oxygen as they are mixed; and (d) means in said conduit means for continuously circulating the mixed gases passed through said conduit means to thoroughly mix same thereby forming the breathing gas.
