Hyperbaric oxygen therapy delivers 100 percent oxygen by using a chamber in which the air can be pressurized more than normal air pressure. The decompression of gas bubbles in your lungs are able to uptake more oxygen in this pressurized state, allowing for a higher saturation of oxygen in the blood.
Oxygen is transported to the body by red blood cells with a protein complex known as hemoglobin. Under a pressurized state, oxygen is dissolved into blood, plasma, central nervous system, lymph, and bone allowing oxygen to reach places that are blocked or restricted by injury or infection. Restoring blood oxygen levels replenishes the tissue and promotes healing.
