Hyperbaric chamber therapy for wounds works by delivering high concentrations of oxygen in a pressurised environment, helping damaged tissue receive the oxygen it needs to heal. For people with slow healing injuries, including diabetic foot wounds, hyperbaric oxygen therapy can improve circulation, reduce infection risk, and support tissue repair when standard treatments are not enough.
Chronic wounds affect thousands of Australians each year, particularly those living with diabetes. When oxygen supply to injured tissue is limited, healing slows and complications increase. Hyperbaric oxygen therapy offers a clinically supported option that enhances the body’s natural repair processes.
What Is Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy, often called HBOT, involves sitting or lying in a specialised chamber while breathing pure oxygen at increased air pressure. This higher pressure allows oxygen to dissolve more effectively into the bloodstream and reach areas with poor circulation.
Under normal conditions, oxygen is carried mainly by red blood cells. In a hyperbaric chamber, oxygen also dissolves into plasma and other body fluids. This helps oxygen reach damaged tissues that may not be receiving enough through regular blood flow.
For wound care, this increased oxygen availability supports:
✓ Collagen production
✓ New blood vessel formation
✓ Reduced swelling
✓ Improved white blood cell function
✓ Decreased bacterial growth
These processes are particularly important for chronic wounds such as diabetic foot ulcers.
Why Wounds Fail To Heal
Most minor cuts and injuries heal within weeks. However, certain wounds become chronic due to underlying health issues. Common factors include:
1. Diabetes
2. Poor circulation
3. Peripheral artery disease
4. Infection
5. Pressure injuries
6. Smoking
For people with diabetes, high blood sugar levels can damage blood vessels and nerves. Reduced sensation in the feet increases the risk of unnoticed injuries. At the same time, impaired circulation slows healing. This combination makes diabetic foot wounds one of the most serious complications of diabetes.
Without effective treatment, these wounds can lead to severe infection and, in some cases, amputation. Early intervention is essential.
Hyperbaric Oxygen Therapy For Diabetic Foot Wounds
Hyperbaric oxygen therapy for diabetic foot wounds is recognised as an adjunct treatment when conventional wound care alone is insufficient. It is typically recommended for chronic ulcers that have not improved after several weeks of standard care.
Clinical research shows that HBOT can:
1. Increase oxygen levels in poorly perfused tissue
2. Support the growth of new capillaries
3. Enhance immune response
4. Reduce the risk of major amputation
By improving oxygen supply, HBOT addresses one of the key barriers to healing in diabetic patients. Oxygen plays a central role in cellular repair and immune defence. When tissues receive adequate oxygen, healing processes can resume more effectively.
In Australia, hyperbaric therapy is used in hospital and specialised clinical settings for selected patients with non healing diabetic foot ulcers.
If you are managing a diabetic wound and feel your recovery has stalled, the team at Folium Health can help assess whether advanced therapies may support your care plan.
The Treatment Process
A typical hyperbaric oxygen therapy session lasts between 60 and 90 minutes. During treatment:
✓ You enter the chamber and relax in a seated or reclining position.
✓ The chamber is gradually pressurised.
✓ You breathe pure oxygen through a mask or hood.
✓ After the session, pressure is slowly reduced.
Most patients require multiple sessions, often five days per week for several weeks. The exact schedule depends on wound severity and overall health.
HBOT is usually combined with:
1. Debridement
2. Infection management
3. Blood sugar control
4. Offloading techniques
5. Appropriate dressings
It is not a replacement for standard wound care but a complementary therapy.
Benefits Of Hyperbaric Chamber Therapy For Wounds
Improved Oxygen Delivery
Oxygen is essential for wound healing. Hyperbaric therapy significantly increases oxygen concentration in tissues, even in areas with compromised circulation.
Enhanced Infection Control
Oxygen supports white blood cell activity. It also creates an environment that is less favourable for certain bacteria, particularly anaerobic organisms.
Stimulated Tissue Repair
HBOT promotes the production of collagen and growth factors, which are crucial for rebuilding damaged tissue.
Reduced Swelling
Pressurised oxygen can help decrease inflammation and fluid accumulation around the wound site.
Lower Risk Of Amputation
For selected patients with diabetic foot ulcers, hyperbaric therapy has been associated with improved healing rates and reduced risk of major amputation.
Who May Benefit
Hyperbaric oxygen therapy may be suitable for individuals with:
✓ Chronic diabetic foot ulcers
✓ Radiation related tissue injury
✓ Compromised skin grafts or flaps
✓ Severe infections affecting soft tissue
✓ Non healing surgical wounds
A thorough medical assessment is necessary before starting treatment. Not everyone with a wound will require HBOT. Factors such as overall health, oxygen levels in the tissue, and response to standard care must be evaluated.
If you are unsure whether advanced wound therapies are appropriate for you, Folium Health offers personalised consultations to explore supportive options aligned with your broader health plan.
Safety And Considerations
Hyperbaric oxygen therapy is generally well tolerated when delivered in a clinical setting. Some people may experience:
1. Mild ear pressure similar to flying
2. Temporary changes in vision
3. Fatigue after sessions
Serious complications are rare but can include oxygen toxicity or lung issues. This is why treatment should only be conducted under medical supervision.
Patients with certain conditions, such as untreated pneumothorax, may not be suitable candidates. A healthcare professional will review your medical history before recommending therapy.
Integrating HBOT Into A Comprehensive Care Plan
For diabetic foot wounds, successful treatment requires more than one intervention. Key components include:
✓ Strict blood glucose management
✓ Regular podiatry reviews
✓ Appropriate footwear
✓ Smoking cessation
✓ Nutritional support
Hyperbaric oxygen therapy works best when integrated into a structured wound management programme. Coordination between GPs, endocrinologists, podiatrists, and wound care specialists improves outcomes.
Folium Health supports Australians seeking evidence informed therapies that complement conventional medical care. If you are exploring ways to improve wound healing outcomes, our practitioners can guide you through available options.
When To Seek Help
You should seek medical attention promptly if you notice:
1. A foot wound that has not improved within two weeks
2. Increasing redness, swelling, or discharge
3. Fever or signs of systemic infection
4. Blackened or dead tissue
Early assessment can prevent serious complications. Diabetic foot wounds should never be ignored.

Frequently Asked Questions
1. How does hyperbaric oxygen therapy help diabetic foot wounds?
It increases oxygen delivery to damaged tissue, supports immune function, stimulates new blood vessel growth, and enhances collagen production. These effects help improve healing in ulcers that have not responded to standard care.
2. Is hyperbaric oxygen therapy painful
No. The treatment is non invasive. Some people feel mild ear pressure as the chamber pressurises, similar to take off or landing during a flight.
3. How many sessions are needed for wound healing
The number of sessions varies. Many patients require 20 to 40 treatments depending on wound severity and response.
4. Can hyperbaric therapy replace standard wound care?
No. It is used as an adjunct therapy. Proper wound cleaning, infection control, blood sugar management, and pressure relief remain essential.
