ABSTRACT:
A portable hyperbaric chamber is provided that allows a person to perform endurance exercise at barometric pressures of from 0 to 10 lbs./square inch greater than ambient. The chamber is portable, semi-spherical and inexpensively constructed of an essentially air-impermeable, flexible material. The chamber is used for endurance conditioning, to improve the athletic performance of people who live at altitudes above seal level. Another embodiment of this invention is the hyperbaric mountain bubble. This embodiment, designed for use at high altitudes to prevent mountain sickness, provides a portable sealed chamber in which a patient may be placed. The pressure inside the chamber is raised, providing an interior environment equivalent to a descent from altitude to as low as sea level, to alleviate the symptoms of mountain sickness. In a further embodiment, the mountain bubble is expanded to provide a high altitude habitat suitable for use as a mountain tent, which may be pressurized or not as desired. The mountain bubble may be equipped with a bladder arrangement to eliminate the need for constant pumping, and may also be constructed for use as a high-altitude tent which can be pressurized or not as desired. A useful embodiment of this invention is the closed circuit rebreather using an oxygen supply and carbon dioxide removal means to provide an extended period of breathing without the need for attention to maintaining a fresh air supply.
