ABSTRACT:
A method and apparatus for inducing hypoxia in persons comprising a hypobaric chamber and means to introduce excess nitrogen into the atmosphere of the chamber, where hypoxia is induced by lowering the pressure within the chamber to a pressure equivalent to a high altitude, but less than 18,000 feet, and introducing an excess amount of nitrogen gas into the chamber, thus lowering the partial pressure of oxygen within the chamber.
