A hypoxic room system for hypoxic training or therapy is provided which simulates oxygen-depleted mountain air. The system employs an oxygen content-reducing device (hypoxicator) which supplies oxygen-depleted air to a hypoxic training room communicating with the device and having ventilating openings for equalizing atmospheric pressure inside the hypoxic room. The system may be applied to interior space inside any structure. The hypoxicator may employ a membrane air-separation principle or a molecular sieve pressure-swing adsorption process.

[ What is claimed is:] [1.] A system for use in an external atmospheric environment of air at an external ambient air pressure and having an ambient oxygen concentration for providing a reduced-oxygen atmosphere to a user, said system comprising:a gas separation device having an inlet intaking an intake gas mixture and first and second outlets, said first outlet transmitting a first gas mixture derived from said intake gas mixture and having a higher oxygen content than the intake gas mixture and said second outlet transmitting a second gas mixture derived from said intake gas mixture and having a lower oxygen content than the intake gas mixture;a breathing chamber having an internal space therein containing air and including an entry communicating with said internal space and through which the user can enter said internal space;said second outlet communicating with said internal space and transmitting said second mixture to said internal space so that said second mixture mixes with the air in the internal space;said first outlet transmitting said first gas mixture to the external atmospheric environment; andsaid breathing chamber permitting the communication of air in at least one direction between the external atmospheric environment and the internal space and in combination with the gas separation device, maintaining the air in the internal space at a pressure generally equalized with the ambient air pressure of the external atmospheric environment and at a substantially constant concentration of oxygen substantially lower than said external ambient oxygen concentration.
