Hyperbaric Oxygen Therapy

Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves breathing pure oxygen in a pressurized chamber. The therapy is based on the principle that oxygen is essential for the proper functioning of the body's tissues and organs.

How it Works

In HBOT, the patient breathes 100% oxygen in a hyperbaric chamber, which is a specially designed chamber that can withstand high pressures. The pressure in the chamber is increased to 2-3 times the normal atmospheric pressure, allowing the oxygen to dissolve more easily into the bloodstream.

Benefits of HBOT

• Increased Oxygen Delivery: HBOT increases the amount of oxygen delivered to the body's tissues and organs, which can help to promote healing and reduce inflammation.
• Improved Wound Healing: HBOT has been shown to enhance wound healing by increasing oxygen delivery to the affected area, reducing bacterial growth, and promoting collagen synthesis.
• Reduced Inflammation: HBOT has anti-inflammatory properties, which can help to reduce swelling and promote healing in conditions such as arthritis and sports injuries.
• Improved Cognitive Function: Some studies have suggested that HBOT may improve cognitive function in individuals with traumatic brain injury, stroke, and other neurological conditions.

Conditions Treated with HBOT

HBOT is used to treat a variety of medical conditions, including:

• Carbon Monoxide Poisoning: HBOT is the primary treatment for carbon monoxide poisoning, as it helps to remove carbon monoxide from the bloodstream and restore oxygen delivery to the body's tissues.
• Decompression Sickness: HBOT is used to treat decompression sickness (the "bends") in divers, which occurs when gas bubbles form in the bloodstream due to rapid changes in pressure.
• Gas Gangrene: HBOT has been shown to be effective in treating gas gangrene, a potentially life-threatening condition caused by bacterial infection.
• Diabetic Foot Ulcers: HBOT may be used as an adjunctive treatment for diabetic foot ulcers, helping to promote wound healing and reduce the risk of amputation.

Risks and Side Effects

While generally considered safe, HBOT can cause some side effects, including:

• Middle Ear Barotrauma: The increased pressure in the hyperbaric chamber can cause ear pain or discomfort due to middle ear barotrauma.
• Sinus Pressure: Some individuals may experience sinus pressure or congestion during HBOT.
• Claustrophobia: The enclosed space of the hyperbaric chamber can cause anxiety or claustrophobia in some individuals.

Contraindications

HBOT is not suitable for everyone, and certain conditions may be contraindicated, including:

• Pneumothorax: Individuals with a collapsed lung (pneumothorax) should not undergo HBOT, as the increased pressure can worsen the condition.
• Severe Chronic Obstructive Pulmonary Disease (COPD): Individuals with severe COPD may experience respiratory distress during HBOT due to the increased pressure.

Training and Certification

HBOT is typically administered by trained healthcare professionals, including physicians, nurses, and hyperbaric technologists. The Undersea and Hyperbaric Medical Society (UHMS) provides training and certification programs for healthcare professionals in HBOT.
