Frequently Asked Questions
FDA approves HBOT for treatment of acute traumatic ischemia, acute anemia, carbon monoxide poisoning, compromised skin flaps, cyanide poisoning, decompression sickness, gas gangrene, necrotizing infections, radiation effects, some forms of osteomyelitis, non-healing wounds, thermal or extensive burns. Beside official FDA approved indications, HBOT is sometimes used and could be effective for off label conditions such as chronic fatigue, depression, treatment of skin conditions, muscle pain, traumatic brain injury, stroke, hearing loss, tinnitus, infections and other conditions.
Treatment with oxygen under the pressure is a very safe procedure. Although very rare side effects and complications could be observed, What are possible side effects from hyperbaric therapy- Side effects from hyperbaric therapy mostly include the effect of increased air pressure which may induce pressure sensation in the ears or sinus pain. Usually a slow increase of pressure decreases the possibility of this type of side effect. Some additional side effects include possibility of visual refractive changes (vision abnormality). It is a side effect which is seen after multiple treatments (usually more than 80 treatments) and as a rule; changes are improving after treatment is stopped. Dental pain could be present in cases when a person already is having dental problems which are starting to manifest under the pressure. Extremely rare pulmonary oxygen toxicity (symptoms are: chest pain, dry cough, decreased vital capacity) is more typical for children and also related to multiple treatments. Another rare complication is pneumothorax which is seen in patients who are smokers or who have personal history of pneumothorax. Seizures could be observed in patients with underlying seizure disorder.
One of the explanations could be the fact that oxygen under the pressure provides a very potent anti-inflammatory effect which could be the main reason for that effect because inflammation as a rule is a part of many medical diseases.
Official definition of Hyperbaric Oxygen Therapy is the therapy, which involves breathing pure ( 100%) oxygen in a pressurized environment.
There are studies, including the recent study from Israel (paper was published in AGING journal in November of 2020) suggesting that HBOT may reverse aging process. The latest study revealed that HBOT affecting/reversing 2 major components of aging: the shortening of telomers (the parts of each chromosome which protect the aging) and accumulation of malfunctioning cells in the body.
There is evidence of potential benefits of HBOT for TBI, although randomized study,
which revealed the potential benefits were small and more studies are needed.
Dr. Paul Harch presented multiple reports regarding the benefits of HBOT in TBI,
including the study in veterans with blast TBI and PTSD ( posttraumatic stress
disorder).
