What is Hyperbaric Oxygen Therapy? Hyperbaric oxygen therapy (HBOT) is the process of breathing 100% oxygen while under increased atmospheric pressure. A treatment that can be traced back to the 1600s, hyperbaric oxygen therapy has been around for centuries. A British clergyman by the name of Henshaw is credited to be the first to build and run the first well-known hyperbaric oxygen chamber. A well-established treatment for scuba diving risks and also for decompression sickness, hyperbaric oxygen therapy is on the cutting edge of treatments for a variety of injuries and illnesses. Some of the other conditions hyperbaric oxygen therapy has been known to help are anemia due to blood loss, gas gangrene, radiation injuries, carbon monoxide poisoning, and much more. The air pressure in a hyperbaric oxygen therapy chamber is increased by two to three times. This improves your lungs\u2019 ability to take in higher amounts of pure oxygen than is possible under normal pressure conditions. This allows your lungs to distribute extra oxygen throughout your body, helping to fight bacteria and prompt the release of growth factors and stem cells to promote healing.
