Hyperbaric Oxygen Therapy (HBOT) involves the breathing of oxygen while the body is placed under increased atmospheric pressure in order to increase oxygenation of tissues as well as fight bacteria, release growth factors and stimulate the release of stem cells from bone marrow. While HBOT has been used for years by deep-sea divers who developed decompression sickness, it is now being used to help a range of conditions from wound healing to sudden deafness. Evidence currently supports use of HBOT for: anemia, brain abscess, arterial gas embolism, burns, decompression sickness, carbon monoxide poisoning, crushing injury, deafness, gangrene, infection of skin or bone that causes tissue death, non-healing wounds, such as a diabetic foot ulcer, radiation injury, skin grafts, and some forms of vision loss. Research and clinical trials are currently underway to determine the efficacy of many other clinical conditions such as: AIDS/HIV, allergies, Alzheimer’s disease, arthritis, asthma, autism, Bell’s palsy, brain injury, cancer, cerebral palsy, chronic fatigue syndrome, cirrhosis, depression, fibromyalgia, gastrointestinal ulcers, heart disease, heatstroke, hepatitis, migraine, multiple sclerosis, Parkinson’s disease, spinal cord injury, and stroke. In addition, athletes have been using HBOT for many years to improve recovery from training efforts.
