A system and method of automatic delivery of appropriate flow rate of oxygen to a person flying in a pressurized aircraft cabin is disclosed. In one embodiment, an adaptable demand dilution oxygen regulator for use inside a pressurized aircraft cabin, includes an oxygen initiation and demand regulation system adapted to be responsive to differential gas pressure in a first altitude range based on a pulmonary capacity of a person flying in the pressurized aircraft cabin and to control flow of pressurized oxygen to a breathing outlet during the first altitude range. The adaptable demand dilution oxygen regulator further includes a cabin air dilution and delivery system, coupled to the oxygen initiation and demand regulation system, adapted to be responsive to differential gas pressure in a second altitude range and to output progressively enriched mixture till 100% pressurized oxygen into a breathing apparatus during the second altitude range.
