Acclimatisation to altitude may be achieved by intermittent exposure to hypoxia in a hyperbaric chamber or by inhaling a hypoxic gas mixture under normobaric conditions. We describe the development of a hypoxic room based on the latter principle. A nitrogen generator based on the vacuum pressure swing adsorption principle reduces the oxygen content of air to 5%. The resultant gas mixture containing 95% nitrogen is pumped into a sealed apartment. The level of oxygen in the appartment is monitored continuously and cannot fall below 11%. Should it fall below a preset value, the nitrogen generator is switched off, closely followed by the activation of fan to transport external air into the apartment. An audible alarm is also activated.<\/p>\n
The hypoxic room has been successfully used by athletes prior to attending the Salt Lake City Olympic games and by alpinists prior to high altitude expeditions.<\/p>\n","protected":false},"excerpt":{"rendered":"
