How does a hyperbaric chamber heal the body?

Hyperbaric chambers accelerate healing by delivering 100% oxygen at high pressure.

Hyperbaric therapy increases air pressure to three times the normal level, forcing oxygen to dissolve directly into blood plasma. This floods the body with up to 15 times more oxygen than usual. The process fuels tissue repair, activates stem cells, and kills harmful bacteria to treat stubborn wounds and infections.

Hyperbaric Oxygen Therapy (HBOT) traces its roots back to 1662 when British physician Nathaniel Henshaw built the 'Domicilium' to treat respiratory diseases. Modern clinical use expanded significantly in the 1930s when the U.S. Navy began using it to treat decompression sickness in divers. Under normal conditions, oxygen is carried primarily by hemoglobin in red blood cells. However, Henry's Law states that the amount of a gas dissolved in a liquid is proportional to its partial pressure.In a hyperbaric chamber, the atmospheric pressure is increased to 2.0 or 3.0 atmospheres absolute (ATA). This allows oxygen to saturate not just the red blood cells but the blood plasma, cerebrospinal fluid, and lymph. This hyper-oxygenation provides the energy needed for white blood cells to kill bacteria and for fibroblasts to synthesize collagen. Studies from institutions like the Mayo Clinic show that HBOT stimulates the release of substances called growth factors and stem cells.The treatment is FDA-approved for 14 specific conditions including carbon monoxide poisoning, gangrene, and non-healing diabetic foot ulcers. Research published in the journal 'Undersea and Hyperbaric Medicine' indicates that HBOT can increase the concentration of circulating stem cells by eightfold. By reducing edema and inflammation, it creates an environment where damaged tissues can finally regenerate. Today, there are over 1,300 accredited hyperbaric facilities across the United States providing this life-saving care.
