Oxygen is essential for life, healing, and cellular function. While most of us get the oxygen we need from normal breathing, certain medical conditions can benefit from increased levels of oxygen delivered in a specialized way. This is where Hyperbaric Oxygen Therapy (HBOT) comes in—a medically approved treatment that has shown powerful benefits for a wide range of health issues. In this article, we’ll explore what HBOT is, how it works, its medical uses, risks, and what to expect during a session.
What Is Hyperbaric Oxygen Therapy (HBOT)?
Hyperbaric Oxygen Therapy (HBOT) is a treatment in which a patient breathes 100% pure oxygen in a pressurized chamber like you see at Amber Oxygen. The atmospheric pressure in the chamber is increased to two to three times higher than normal air pressure. This enables the lungs to gather significantly more oxygen than would be possible under normal conditions.
The increased oxygen in the bloodstream promotes faster healing by helping fight bacteria, stimulating the release of growth factors, and enhancing the body’s ability to regenerate tissues.
How HBOT Works
Under increased pressure, oxygen dissolves more easily into the blood plasma (the fluid part of blood), not just the red blood cells. This allows more oxygen to reach tissues that may be damaged or deprived of adequate oxygen supply due to injury, infection, or inflammation.
The process typically involves:
- The patient entering a specially designed monoplace (single-person) or multiplace (multiple-person) chamber
- The pressure gradually increasing to 2–3 atmospheres absolute (ATA)
- Sessions lasting 60–90 minutes, with the patient breathing pure oxygen throughout
- The procedure is painless and non-invasive, though patients may feel pressure changes in their ears, similar to flying in an airplane.
Medical Conditions Treated with HBOT

HBOT is FDA-approved for a range of conditions and continues to be explored for others. Here are some of the most common uses:
1. Decompression Sickness (DCS)
Originally developed to treat divers suffering from “the bends,” HBOT rapidly eliminates nitrogen bubbles in the bloodstream, relieving pain and preventing long-term damage.
2. Carbon Monoxide Poisoning
HBOT is a frontline treatment for carbon monoxide poisoning, helping to displace carbon monoxide from hemoglobin and restore normal oxygen transport in the body.
3. Non-Healing Wounds
Patients with diabetic foot ulcers or radiation-related injuries often benefit from HBOT. Increased oxygen promotes new blood vessel formation and enhances the healing process in damaged tissues.
4. Infections
Severe or necrotizing infections, such as gas gangrene, can be managed with HBOT. The therapy helps kill anaerobic bacteria and improves the effectiveness of antibiotics.
5. Radiation Injuries
Patients who have received radiation therapy for cancer may suffer from delayed tissue damage, particularly in the jaw or bladder. HBOT can reverse some of these effects by increasing oxygen supply and regenerating damaged blood vessels.
Emerging and Off-Label Uses
Research into HBOT continues to grow. Some of the emerging and off-label uses include:
- Traumatic brain injury (TBI)
- Stroke recovery
- Post-COVID fatigue and brain fog
- Autism spectrum disorder (ASD)
- Sports injuries
- Multiple sclerosis (MS)
While these applications are still being studied and may not be FDA-approved, many patients report positive results.
Benefits of HBOT
Hyperbaric oxygen therapy offers a range of potential benefits for those who need enhanced oxygenation for healing or recovery:
- Improved oxygen delivery to tissues
- Faster wound healing
- Reduced inflammation
- Enhanced immune response
- Stimulation of stem cells and new blood vessel growth
- Increased effectiveness of antibiotics
- For chronic conditions, HBOT may improve quality of life and reduce the need for surgery or long-term medications.
Risks and Side Effects
While HBOT is generally safe when administered in a controlled medical environment, there are some potential side effects to consider:
1. Barotrauma
Changes in pressure can affect the ears, sinuses, or lungs. Ear pain is the most common issue, though serious barotrauma is rare.
2. Oxygen Toxicity
Breathing high concentrations of oxygen over prolonged periods can affect the lungs or central nervous system. This is carefully monitored during treatment.
3. Vision Changes
Temporary nearsightedness (myopia) may occur after repeated sessions, but it usually resolves after stopping therapy.
4. Claustrophobia
Some patients may feel anxious in the enclosed chamber. Sedatives or alternative therapy approaches may help manage this.
What to Expect During a Session
A typical HBOT session involves the following steps:
- Pre-Treatment Assessment: The doctor reviews medical history and determines eligibility.
- Preparation: Patients wear cotton garments and remove any flammable items or devices.
- Chamber Entry: The patient enters the chamber—either lying down (monoplace) or seated (multiplace).
- Pressurization: The chamber pressure gradually increases, and the patient may feel fullness in the ears.
- Treatment: Patients breathe pure oxygen for 60–90 minutes. They may read, nap, or watch TV during this time.
- Decompression: The pressure is slowly normalized before exiting the chamber.
Most treatment courses include 20 to 40 sessions, depending on the condition being treated.
Who Should Avoid HBOT?
Certain individuals may not be suitable candidates for HBOT. Contraindications include:
- Untreated pneumothorax (collapsed lung)
- Recent ear or Rhinoplasty surgery or severe sinus infections
- High fever
- Certain types of lung disease (e.g., COPD with air trapping)
- A full medical evaluation is necessary to rule out these risks.
- Breathing New Life into Recovery
- Have has recent dental work done such as dental implants
Hyperbaric Oxygen Therapy is a powerful tool in modern medicine that harnesses the body’s natural healing mechanisms by delivering oxygen at higher pressures. From treating life-threatening conditions like carbon monoxide poisoning and decompression sickness to promoting the healing of chronic wounds and radiation injuries, HBOT offers a versatile, non-invasive solution with proven results.
If you’re struggling with a health issue that may benefit from oxygen therapy, speak with your healthcare provider about whether HBOT is right for you. With advancing research and expanding applications, this therapy continues to evolve and bring hope is a safe, effective treatment that enhances healing by increasing oxygen delivery to the body. From chronic wounds to carbon monoxide poisoning, HBOT offers hope for faster recovery and better outcomes
