Because oxygen is king among all other elements found in the human body, it is also the best healer as well. Since the medical world finally took notice to the vast rehabilitative and preventative effects associated with oxygen therapy, the hyperbaric chamber has become a fixture in hospitals, clinics, doctors offices, and assisted living homes of all sizes. Day spas, movie sets, luxury jets, and Michael Jackson are all known to utilize oxygenation for natural skin care and anti aging purposes while athletes, cancer patients, people with autism, brain injury victims, and the elderly use oxygen as a means to rehabilitate from physical rehabilitation. Oxygen fills 65% of the air we as humans are made of. There is no question that pure oxygen can rejuvenate cell tissue in almost all circumstances if applied correctly, at a pressure higher than atmospheric. Hyperbaric Oxygen Therapy is most efficiently administered in a special chamber for this specific purpose. A hyperbaric chamber is any enclosure capable of delivering pure oxygen at such a pressure. This said, chambers vary in size, shape, power, and mobility.
