About Hyperbaric Therapy or Hyperbaric Oxygen Therapy (HBOT)
Hyperbaric chambers, used in hyperbaric therapy (HBOT), are any number of enclosures, which can be pressurized to allow a person inside to experience higher atmospheric pressures than the normal environmental pressures. For example, a treatment at an elevation of 12,000 feet above sea level using a 4 psi (1.27 ATA) can simulate a decent of ~5,843 feet to 6,157 feet above sea level.
At higher elevations, the barometric pressure is lower. This decrease of pressure also decreases the oxygenation of blood, and is known as anoxia where molecules of oxygen exert less pressure on the walls of the alveoli (Dalton's Law). Hyperbaric Oxygen Therapy (HBOT) follows this law.
