Imitation of nature – not so easy… 

Already at the beginning of the twentieth century, major changes in the blood picture were found in the first mountaineers and climbers living in natural conditions heights. At the same time addressed in the study so far unknown altitude sickness. The resulting preparation of the initial clues adaptation.




The first attempts to apply simulated altitude conditions took place in 1939-1943. They showed that slight hypoxia results in positive effects in the form of improving pulmonary ventilation, increased hemoglobin levels and consequent improvement in blood oxygen saturation. He then formed in the high Alps first healing clinic with the help of the altitude symptoms of asthma. Altitude training heyday came in the late 60’s, after  the Olympic Games in Mexico (1968).

The next steps in research on the use of artificially induced exposure to hypoxia has been made on the basis of military applications and gain space. Terms of heights caused by low-pressure chambers are pumping air into today used during the initial acclimation bomber pilots and astronauts to fly at high altitude. Staying in such chambers hipobaric (low pressure), however, is generally poorly tolerated by the people because of significant pressure differences. There is a need to apply the principles of decompression (gradual return to „normal” pressure), which consumes a lot of time.




Another attempt to create artificial conditions of hypoxia became simulating high-altitude climate through the use of respirators, whose task is bringing a mixture of air with nitrogen with a reduced level of oxygen in the inhaled air. And this solution is not satisfactory. The reasons are the major inconvenience of use, disorder, normal breathing, sweating, traffic restrictions and uncontrolled increase of the COconcentration due to rebreathing exhaled part already before the air.

Next try to create an artificial elevation is blown into the spaces of pure nitrogen from a small portable generators, to displace a certain amount of oxygen in the room. This system, however, because of the high jumping of the simulated height (as of 2000 m?) Extremely unstable and even dangerous for the user. CO2 absorption requires constant, temporary opening windows, and is also very expensive to maintain.




LOXYS system, the only one on the market is devoid of the disadvantages described earlier, allowing for a comfortable stay in a stable altitude. The details of the system can be read here.
