In a hyperbaric chamber, the body undergoes profound physiological changes due to the increased pressure and the high concentration of oxygen. Under elevated pressure, oxygen dissolves more readily into the bloodstream, reaching tissues with compromised blood supply or damage.

This enhanced oxygen delivery promotes cellular repair and function, facilitating the healing process. Moreover, the high oxygen levels stimulate the release of growth factors like vascular endothelial growth factor (VEGF), which promotes the formation of new blood vessels, a process known as angiogenesis. This neovascularisation improves blood flow and oxygenation to damaged tissues, aiding in long-term healing and recovery.
