Hyperbaric therapy, conducted within a hyperbaric chamber, is a scientifically proven medical treatment that exposes the body to increased atmospheric pressure in a controlled environment. This heightened pressure allows the lungs to absorb higher levels of oxygen than would be possible at normal air pressure. The oxygen-rich blood then circulates throughout the body, enhancing the body’s natural healing processes and promoting the repair of damaged tissues.

How It Works

The hyperbaric chamber is a sealed enclosure—either rigid or flexible—that can be pressurized to levels beyond the ambient atmosphere. Patients inside the chamber breathe 100% oxygen, typically for sessions lasting from 60 to 90 minutes. These sessions may be repeated over several days or weeks, depending on the condition being treated.


The influx of oxygen at such high levels has multiple therapeutic effects:

  • Accelerated Healing: Increases in oxygen levels promote faster wound healing, especially useful in diabetic ulcers, radiation injuries, and infections where blood flow is compromised.
  • Anti-Inflammatory Effects: Hyperbaric oxygen therapy reduces inflammation, which can help in conditions like inflammatory bowel diseases and cystitis.
  • Neurological Improvement: It is beneficial in the recovery of brain and spinal cord injuries by reducing swelling, preserving damaged tissues, and improving recovery outcomes.
  • Infection Control: High oxygen levels have an antibacterial effect and are particularly effective in fighting anaerobic bacterial infections and enhancing the effects of certain antibiotics.


Hyperbaric therapy is used for a variety of health conditions, including, but not limited to:

  • Decompression sickness (often affecting divers)
  • Severe anemia
  • Brain abscesses
  • Carbon monoxide poisoning
  • Crush injuries
  • Gangrene
  • Skin grafts and flaps that are at risk of tissue death
  • Thermal burns

Safety and Considerations

While hyperbaric therapy is generally safe, it is not suitable for everyone. Potential risks, though rare, include middle ear injuries, lung collapse due to pressure changes, and temporary vision changes. Prior to starting treatment, a comprehensive assessment by a healthcare professional is necessary to ensure safety and appropriateness of the therapy for specific conditions.

By providing a high-oxygen environment, hyperbaric therapy fosters a conducive atmosphere for the body’s healing mechanisms to operate more effectively, making it a valuable tool in both acute and chronic care.
