Hyperbaric Chamber

Hyperbaric oxygen therapy (HBOT) is a treatment method that uses highly pressurized oxygen to speed up healing of certain injuries, infections and disease conditions. This treatment has been FDA-approved for use in patients with several conditions, including carbon monoxide poisoning and severe burns, but has also proven effective in off-label treatments in numerous systems of the body.

Reasons For HBOT

Hyperbaric oxygen treatments are used for a wide variety of purposes, frequently with great success. Although HBOT is commonly used to treat wounds, infections and other temporary conditions, it can also help improve chronic neurological, vascular and ophthalmic conditions.

FDA Approved Uses Of HBOT

The most common uses of HBOT are for treating wounds that are not healing normally and certain types of toxicity. The FDA approves HBOT as a method of treatment for:

  • Air or gas embolism
  • Carbon monoxide poisoning
  • Crush injury
  • Decompression sickness, commonly known as "the bends"
  • Healing of diabetic wounds
  • Anemia
  • Intracranial abscess
  • Necrotizing fasciitis
  • Osteomyelitis (bone infection)
  • Radiation injury
  • Skin grafts
  • Serious burns

Off-Label Uses Of HBOT

Many patients with neurological conditions lack sufficient oxygen and blood flow to the brain. During HBOT, oxygen is forced into the brain and once-dormant areas can be reawakened. For this reason, although not yet officially FDA-approved for neurological conditions, HBOT has proved helpful in improving gross and fine motor skills, vision, hearing and speech function after traumatic brain injury.

The healing powers of HBOT have also been reported in treating disorders in other specialties. HBOT has been shown to result in improvement in patients with the following conditions, even though its use in such cases is not yet FDA-approved there is anecdotal evidence to support claims of improved functioning after HBOT in patients with:

  • Cerebral palsy or multiple sclerosis
  • Stroke or brain injury
  • Cancer or HIV
  • Heart attack
  • Fibromyalgia or chronic fatigue syndrome
  • Autism
  • Allergies, arthritis, cirrhosis
  • Gastrointestinal ulcers
  • Certain eye diseases

It is difficult to refute such claims since nearly any type of disorder can benefit from increased oxygen levels.

The HBOT Procedure

During HBOT treatment sessions, patients are placed in a chamber with increased atmospheric pressure that allows them to breathe in oxygen under three times more pressure than the oxygen in normal air. As the increased oxygen levels saturate the tissues of the body, the body's natural healing process is stimulated, enabling new blood vessels to grow, inflammation to decrease, toxins to be deactivated and infections to be resisted. Patients remain in the hyperbaric chamber for between 1 and 2 hours.

In order for patients to see effective results from HBOT, treatment sessions may be required every day for up to 6 weeks.
