Supporters of the more questionable uses of hyperbaric oxygen therapy (HBOT) claim that the same type of oxygen treatment that helps scuba divers recover from the effects of decompression sickness may provide a cure for a number of diseases, including AIDS, Alzheimerâ€™s and cancer. Although HBOT is a legitimate treatment option for a number of health conditions, the Food and Drug Administration (FDA) wants people to know that for others, itâ€™s anything but a cure-all.
HBOT involves the breathing of pure oxygen while in a sealed, pressurized (up to 3 times the normal atmospheric pressure) treatment chamber. Under these conditions, your lungs can take in as much as 3 times the amount of oxygen than they could while breathing oxygen in a room with normal air pressure. Some chambers accommodate a single patient, while others hold up to a dozen.
According to the Hyperbaric Oxygen Therapy Committee, HBOT is approved for the following conditions:1
There have been a number of treatment centers in the past few years that have promoted the use of HBOT for the treatment of any number of diseases. The FDA warns the public that HBOT therapy has NOT been proven clinically safe or effective in treating AIDS, Alzheimerâ€™s, asthma, Bellâ€™s palsy, brain injury, cerebral palsy, depression, heart disease, multiple sclerosis, Parkinsonâ€™s disease, spinal cord injury, stroke, hepatitis or migraine. People who incorrectly believe that HBOT can cure a condition for which itâ€™s not been approved may be endangering their health. They may even experience a worsening of the condition for which theyâ€™re seeking treatment.2 Before undergoing HBOT, discuss all your options with your primary care physician.
