Approved Indications for Hyperbaric
Oxygen Therapy

Listed here are the approved indications for Hyperbaric Oxygen Therapy (HBOT) by the Undersea & Hyperbaric Medical Society.

Air or Gas Embolism

A dangerous condition where air bubbles block blood flow. HBOT helps by shrinking these bubbles and restoring circulation.

Carbon Monoxide Poisoning

HBOT quickly removes carbon monoxide from the bloodstream, helping to restore oxygen levels in your body.

Clostridial Myonecrosis (Gas Gangrene)

A dangerous condition where air bubbles block blood flow. HBOT helps by shrinking these bubbles and restoring circulation.

Crush Injuries & Compartment Syndrome

HBOT reduces swelling and helps improve oxygen delivery to damaged tissues, speeding up recovery after severe trauma.

Decompression Sickness (The Bends)

Divers experiencing decompression sickness benefit from HBOT, which reduces nitrogen bubbles in the bloodstream.

Delayed Radiation Injury (Soft Tissue and Bone)

HBOT improves blood flow and healing in tissues damaged by radiation therapy.

Diabetic Foot Ulcers and Other Problem Wounds

HBOT enhances oxygenation in poorly healing wounds, significantly improving recovery rates in diabetic patients.

Compromised Skin Grafts & Flaps

HBOT supports the healing of skin grafts and flaps that are at risk of failing by promoting healthy blood flow.

Thermal Burns

For serious burns, HBOT speeds healing and reduces the risk of infection by increasing oxygen delivery to the affected areas.

Necrotizing Infections

Life-threatening infections in soft tissue, such as necrotizing fasciitis, respond well to HBOT as it helps fight infection and heal tissue.

Osteomyelitis (Chronic Bone Infection)

HBOT helps treat persistent bone infections by delivering oxygen to infected areas, boosting the immune response.

Sudden Sensorineural Hearing Loss

When hearing loss occurs suddenly, HBOT may improve oxygen supply to the inner ear, supporting hearing recovery.

Radiation Proctitis, Cystitis, Enteritis

These painful conditions are side effects of radiation therapy, and HBOT can alleviate discomfort and promote healing.

Refractory Anaemia

In cases where blood transfusions aren’t possible or effective, HBOT enhances oxygen delivery in anaemic patients.

Intracranial Abscess

HBOT helps reduce the size of brain abscesses and enhances the effectiveness of antibiotics in severe cases.

Avascular Necrosis (Osteonecrosis)

Avascular necrosis is a condition where bone tissue dies due to lack of blood supply, often leading to joint collapse. HBOT can promote new blood vessel formation and improve oxygen delivery to the affected bone, slowing the progression of the disease and aiding in recovery.

Patient Management
During HBOT

Managing patients who are undergoing Hyperbaric Oxygen Therapy (HBOT) requires careful attention to several clinical factors to ensure effective treatment, minimize risks, and optimize patient outcomes. The role of HBOT is to increase oxygen delivery to damaged tissues, reduce inflammation, promote angiogenesis (the formation of new blood vessels), and support wound healing.

Barotrauma

As patients are exposed to increased atmospheric pressure, barotrauma (injury caused by pressure changes) can occur, particularly affecting the middle ear, sinuses, or lungs.

Patients should be educated on how to equalize pressure in their ears during the session (swallowing or yawning) and be monitored for discomfort.

Oxygen Toxicity

Pulmonary oxygen toxicity causes coughing, chest pain and breathing difficulties.

CNS oxygen toxicity includes nausea, confusion, twitching, or seizures.

Monitor patients closely for early signs of oxygen toxicity.

Claustrophobia

Some patients may feel anxious or claustrophobic inside the hyperbaric chamber.

Providing reassurance, creating a calm environment, and, if necessary, mild anxiolytics can help manage these symptoms.

Ocular Changes

Prolonged exposure to high-pressure oxygen may induce myopia (nearsightedness), which typically resolves after HBOT is discontinued.

Regular monitoring of visual changes should be part of patient management.

Contraindications and Precautions

Understanding contraindications and taking precautions for certain patient populations is crucial to avoid complications during HBOT. Contraindications are classified as absolute or relative.

N

Absolute Contraindications

Untreated pneumothorax: This condition poses a significant risk of lung collapse during HBOT due to pressure changes. It must be ruled out or treated prior to therapy.
Certain Chemotherapy Agents: Some chemotherapy drugs (e.g., doxorubicin, bleomycin) can interact negatively with hyperbaric oxygen and should be avoided in patients undergoing HBOT.

N

Relative Contraindications

Respiratory infections or conditions (COPD, asthma) may increase the risk of barotrauma or oxygen toxicity.

Pregnancy: HBOT is usually deferred during pregnancy unless for life-threatening conditions (carbon monoxide poisoning) because of limited research on its safety.

Seizure history: Patients with a history of seizures require cautious monitoring due to the risk of oxygen-induced seizures.

Combining HBOT with Other Therapies

Managing patients who are undergoing Hyperbaric Oxygen Therapy (HBOT) requires careful attention to several clinical factors to ensure effective treatment, minimize risks, and optimize patient outcomes. The role of HBOT is to increase oxygen delivery to damaged tissues, reduce inflammation, promote angiogenesis (the formation of new blood vessels), and support wound healing.

Antibiotics

HBOT can enhance the efficacy of antibiotics, particularly in the treatment of chronic infections like osteomyelitis or necrotizing soft tissue infections, by increasing tissue oxygenation, which enhances immune response and antibiotic penetration into infected tissues.

Surgical Interventions

In cases where radionecrosis, diabetic foot ulcers and osteomyelitis has caused tissue or bone damage, surgery may be necessary to remove necrotic tissue or repair the affected area. HBOT plays a supportive role in improving tissue oxygenation pre- and post-surgery, enhancing wound healing and reducing the risk of infection.

Wound Care

For chronic wounds, HBOT can be part of a comprehensive treatment plan involving advanced wound care techniques, including debridement, negative pressure wound therapy, or the application of growth factors. Coordination between wound care specialists and hyperbaric practitioners is essential.

Follow-Up Care and Adjusting Treatment Plans

HBOT treatment plans typically consist of a series of sessions, with the number of treatments tailored to the patient’s condition and progress. Ongoing assessment and follow-up are key.

Regular Assessment

We assess patient progress after every 5–10 treatments, adjusting the number of HBOT sessions based on the healing response and clinical outcomes.

Monitoring for clinical improvements in pain, wound healing, infection control, and overall functional status should guide treatment modifications.

Post-HBOT Care

After the course of HBOT is completed, follow-up care is essential. This may include wound care assessments, monitoring for late side effects, and coordination with other specialists for continued management.

Patient Education and Psychological Support

Managing patients during HBOT also involves providing thorough education on what to expect during treatment and addressing any concerns.

Pre-Treatment Counseling

We explain the purpose of HBOT and its expected benefits in lay terms. Ensure that patients are aware of potential side effects and how they can manage discomfort (equalizing ear pressure).  

Psychological Support

For patients undergoing treatment for long-term conditions, the psychological impact of the disease and the treatment process should not be overlooked. Offering mental health support or referring to counseling services can improve patient compliance and overall well-being.
