Mild Hyperbaric Chambers

In the late 1980s, while lecturing in Boulder, Colorado, I met with Professor R. Igor Gamow, who was interested in human performance at various altitudes. He invited me to his lab in the chemical engineering department of the University of Colorado, where he was working on a portable mild hyperbaric chamber for use in mountaineering. Climbers who experience mountain sickness at very high altitudes risk death if not carried down to safer altitudes, which is often a difficult task, and this new portable chamber, operated with a foot pump, would soon save lives. Gamow’s portable hyperbaric chamber compresses the air inside a lightweight nylon inflatable “bag,” creating a highpressure environment that mimics low altitude. Even without adding additional oxygen, the body’s ability to get more oxygen out of the compressed air inside increases significantly, just like at lower altitudes.

I immediately saw two benefits beyond those for the mountaineering community. One was to help endurance athletes recover more quickly and effectively, because the chamber would simulate lower altitude and increased oxygen uptake. Another was for the improvement of overall wellness and the treatment of various health problems.
