Oxygen delivery can sometimes be disrupted to cells and tissues due to poisoning, disease or injury. This costs cells varying degrees of the necessary oxygen required by them for healing. Normal air is approximately 20 percent oxygen, but Hyperbaric Oxygen Therapy provides additional oxygen to the tissues by having a patient breathe pure oxygen after being placed in a chamber pressurized with compressed air.During the average treatment, the chamber can be pressurized up to 2.5 times the normal atmospheric pressure. Hyperbaric Oxygen Treatment can be used as the sole treatment of the affliction or in conjunction with other types of treatment, including antibiotics and surgery. Hyperbaric Oxygen Therapy is beneficial in that it speeds the healing process of chronic wounds and helps reduce the risk of amputation of the lower limbs in diabetes patients. In other patients, it decreases swelling, helps fight infection by making antibiotics work more efficiently, and rids the body of many toxic poisons such as carbon monoxide. It also helps promote the growth of new blood vessels in tissues that have been deprived of oxygen.It's now used for treatment of problems related to stroke, cerebral palsy, brain injury, multiple sclerosis, macular degeneration and other disorders. During the treatments, pressure changes will cause patients to notice a popping of the ears. This can be alleviated by swallowing, chewing gum or yawning. Some temporary vision changes may occur during the course of treatment, with vision returning to the patient's normal level after treatments are completed.Although Hyperbaric Oxygen Therapy has been around for years, it has recently gained recognition for the treatment of many conditions. Typical treatments are 90 minutes a day, 5 days a week. A physician will determine the number of treatments needed on a case-by-case basis. A medical professional should remain with the patient at all times during the procedure.
