What is Hyperbaric Wound Care
Hyperbaric wound care refers to a medical treatment called Hyperbaric Oxygen Therapy (HBOT). In this treatment, the patient breathes 100% pure oxygen inside a special chamber that is pressurized higher than normal air. This chamber is called a hyperbaric chamber. The high-pressure environment allows the body to take in much more oxygen than it normally can.
How it Works
Increased Oxygen Delivery
Inside the hyperbaric chamber, the increased pressure helps oxygen dissolve more easily into the blood plasma (the liquid part of the blood). This allows oxygen to travel to damaged tissues, even those that are not getting enough oxygen due to poor blood flow (called ischemic areas).
Oxygen to the Wound
This oxygen-rich blood reaches the wound site, even in places where circulation is weak. Because of this, hyperbaric chambers play a very important role in helping oxygen reach the wound. Without enough oxygen, wounds may take a long time to heal or get worse.
Promotes Healing
The extra oxygen provided by hyperbaric oxygen therapy does many helpful things. It helps the body fight infection, encourages the growth of new blood vessels (a process called angiogenesis), and supports the work of key healing cells. These include fibroblasts, which make collagen and help build new tissue, and other cells that are essential for faster and healthier wound healing.
Science Behind HBOT and Wound Healing
Boosting Body’s Healing Power
Hyperbaric oxygen therapy (HBOT) helps the body heal by giving damaged tissues more oxygen than normal. Oxygen is essential for cells to work properly, especially when there is an injury. With HBOT, oxygen levels in the blood increase, allowing the body to repair wounds more effectively and faster.
Immune System Support
Breathing pure oxygen under pressure improves the immune system’s ability to fight infections. It strengthens white blood cells, which are responsible for destroying harmful bacteria. This is important for keeping wounds clean and preventing infections during healing.
Angiogenesis
HBOT encourages the body to grow new capillaries—tiny blood vessels that deliver oxygen and nutrients to tissues. This process is called angiogenesis. When more capillaries form around a wound, blood flow improves, and healing becomes faster and more complete.
Fibroblast Activation
Oxygen plays a major role in helping fibroblasts, special cells that produce collagen. Collagen is a protein that acts like a scaffold for new tissue. With HBOT, fibroblasts become more active and help rebuild the wound area with strong, healthy tissue.
Antimicrobial Effects
Many harmful bacteria, especially anaerobic bacteria, cannot survive in high-oxygen environments. HBOT raises oxygen levels to a point where these bacteria are destroyed. At the same time, white blood cells become stronger and more effective at removing infection from the wound.
Reduced Edema
HBOT can lower edema, which is the medical term for swelling. When swelling goes down, there is less pressure on nearby tissues and blood vessels. This improves blood circulation and allows more oxygen to reach the wound, helping it heal faster.
Stem Cell Generation
HBOT helps the body create stem cells, which are special cells that can develop into different types of cells, such as skin, blood, or muscle cells. These stem cells are important for forming new tissue and speeding up the healing process, especially in deep or chronic wounds.
New Tissue Growth
One of the major benefits of HBOT is that it supports the growth of new skin, blood vessels, and connective tissue. By increasing oxygen levels in the wound area, the body is able to repair damaged parts and rebuild them with healthy, functioning tissue.
Is Hyperbaric Oxygen Therapy Safe for Everyone?
Hyperbaric Oxygen Therapy (HBOT) is a treatment used to help wounds heal faster. It works by allowing the body to take in more oxygen under high pressure. This extra oxygen helps tissues heal, fights infection, and improves blood flow. Although HBOT is very helpful for many wound care patients, it is not safe for everyone. Some health conditions can make HBOT dangerous.
Generally Safe – But Not for Everyone
Most people can safely receive HBOT when it is done under medical supervision. However, some individuals have medical problems that increase their risk of serious side effects during the treatment. These people should avoid or delay HBOT until it is safe to proceed.
People with a Collapsed Lung (Pneumothorax)
A collapsed lung, known medically as pneumothorax, is a condition where air leaks into the space between the lung and the chest wall. This causes part or all of the lung to collapse.
In HBOT, pressure is increased, and this can worsen a collapsed lung or make it more painful. For this reason, people with pneumothorax are usually not allowed to undergo HBOT until it is treated.
People with Lung Diseases
People with chronic lung diseases such as:
- COPD (Chronic Obstructive Pulmonary Disease)
- Cystic Fibrosis
- Emphysema
may have weakened or damaged lungs. HBOT can increase the chance of lung rupture or a collapsed lung in these patients. These conditions also make it harder for the body to handle pressure changes safely. So, these individuals must be carefully evaluated before receiving HBOT.
People with Fever or Cold
Having a fever or cold may seem minor, but it can still make HBOT uncomfortable or even dangerous. For example:
- A cold can cause sinus or ear pressure, leading to pain or injury inside the ears.
- A fever may signal an active infection, and the body’s reaction to pressure changes may be stronger or unpredictable.
It is better to wait until these symptoms go away before starting HBOT.
Recent Ear Injury or Ear Surgery
The ears are sensitive to pressure changes. During HBOT, the pressure inside the chamber increases, similar to the feeling of ears “popping” on an airplane.
- If someone has had recent ear surgery or a damaged eardrum, HBOT may cause pain, re-injury, or even hearing loss.
- These people should get approval from a doctor before beginning HBOT.
Discussion with a Healthcare Provider Is Important
Before starting HBOT, patients should have a full medical review with a healthcare provider. The doctor needs to know:
- All current and past health conditions
- All medications are being taken
- Any medical implants or devices inside the body
For example:
- Older pacemakers (from the 1960s) may not work properly under pressure.
- Cochlear implants or metal implants might react poorly in the chamber.
This step is very important for safety and proper planning. It helps the healthcare team know whether HBOT is the right treatment or if changes are needed before beginning.
Approved Uses for Hyperbaric Oxygen Therapy
The U.S. Food and Drug Administration (FDA) has approved Hyperbaric Oxygen Therapy (HBOT) for treating certain medical conditions. These include:
- Air or Gas Embolism
This happens when air or gas bubbles enter the blood vessels. These bubbles can block blood flow and cause serious damage to organs. Hyperbaric oxygen therapy helps reduce the size of these bubbles and restores normal circulation.
- Decompression Sickness (The Bends)
Common in scuba divers who come up too quickly, decompression sickness occurs when nitrogen bubbles form in the body. HBOT helps eliminate these bubbles and relieves pain, swelling, and other symptoms.
In cases of serious burns, HBOT can help by increasing oxygen flow to damaged tissue. This supports faster healing and lowers the risk of infection.
- Carbon Monoxide Poisoning
Breathing carbon monoxide reduces oxygen in the body and can be deadly. HBOT gives high levels of oxygen, which quickly replaces the carbon monoxide in the blood and help prevent brain and heart damage.
- Gas Gangrene
Gas gangrene is a dangerous infection caused by Clostridium bacteria, which releases toxins and gas into tissues. HBOT slows the spread of the bacteria, helps kill them, and supports tissue healing.
- Hearing Loss (Sudden Sensorineural Hearing Loss)
In some cases of sudden hearing loss, HBOT can improve oxygen flow to the inner ear. This may help restore some hearing when used early in treatment.
- Wounds (Skin Cuts or Breaks)
For serious or slow-healing wounds, HBOT improves blood flow and delivers more oxygen to support healing. It is especially useful for wounds in people with diabetes or poor circulation.
- Vision Loss
HBOT is sometimes used to treat sudden vision loss due to blocked blood vessels in the eye. It helps by increasing oxygen supply to the retina and reducing further damage.
- Radiation Injuries
Some people experience tissue damage after radiation treatments (e.g., for cancer). HBOT helps repair damaged blood vessels and tissue, especially in areas like the jaw, bladder, or bowel.
- Severe Anemia
When someone loses a lot of blood and can’t get a transfusion right away, HBOT can temporarily supply extra oxygen to the body’s organs and tissues.
- Severe Bone and Skin Infections
In infections that don’t respond well to regular treatment, HBOT can help by increasing oxygen in the affected area, making it easier for the body to fight bacteria and heal.
- Skin Grafts
For skin grafts that are at risk of failing (not attaching or healing properly), HBOT helps improve oxygen and blood supply, which increases the chance of successful healing.
- Crush Injuries
Crush injuries happen when a body part is squeezed under heavy pressure. This damages blood vessels and tissues. HBOT reduces swelling and helps bring oxygen to the injured area to speed up recovery.
Unapproved Uses of Hyperbaric Oxygen Therapy
Some medical spas or alternative health centers advertise HBOT for treating conditions that are not approved by the U.S. Food and Drug Administration (FDA). These claims can be misleading and may cause people to rely on treatments that have not been proven to work. Using HBOT for unapproved purposes can be unsafe or ineffective.
There are several conditions for which HBOT is sometimes falsely promoted, including:
- Anti-aging or age-related issues
- Autism spectrum disorder (ASD)
- Cerebral palsy
- COVID-19
- Depression
- Hair loss (alopecia)
- HIV and AIDS
- Migraine headaches
- Sports injuries
- Strokes
These uses are not supported by strong scientific research, and using HBOT for these conditions is not currently approved by major medical authorities.
Lack of Research
There is not enough scientific research or testing to show that HBOT can safely and effectively treat the above conditions. Without proper studies, the risks and benefits are unclear. Medical treatments should always be based on solid evidence.
Recommendation
HBOT should only be used for conditions that are officially approved by medical experts. It is important to receive this treatment from an experienced healthcare provider in an accredited medical facility. Patients should check whether the provider has certification from a trusted organization, such as the Undersea and Hyperbaric Medical Society (UHMS). This ensures that the therapy is given in a safe and professional setting.
Treatment Process: Inside the Hyperbaric Chamber
Before Hyperbaric Oxygen Therapy
Assessment
The medical team will first check the patient’s health condition, age, and any other medical issues. This helps decide how long each session should last and how many sessions are needed. The treatment plan depends on how serious the wound is and how well the body can heal.
Medications & Implants
All medications and any medical devices inside the body (such as pacemakers or joint implants) must be discussed with the healthcare team. This is important because some devices or drugs might not be safe inside the chamber during oxygen therapy.
Skin Care Products
It is important to talk about any lotions, creams, or skin products being used. Pure oxygen inside the chamber can cause certain products to catch fire at lower temperatures. For safety, the skin must be clean and free of any flammable substances.
Preparation
Before entering the chamber, patients change into a hospital gown. All metal objects, jewelry, or electronic devices must be removed to avoid sparks or accidents. Only a small plastic bottle of water is usually allowed during the session for safety reasons.
Restroom Use
Patients are advised to use the restroom before the treatment begins. Each hyperbaric session usually lasts one to two hours, and there are no breaks once the session starts.
During Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy (HBOT) is a treatment where the body breathes in 100% pure oxygen inside a special chamber. This process helps wounds heal faster by sending more oxygen to the damaged tissues. The experience can vary depending on the type of chamber used.
Chamber Types
There are two main types of hyperbaric chambers used in wound care:
- Monoplace Chamber: This chamber is made for one person at a time. The patient lies on a padded table, which slowly slides into a long, clear tube filled with oxygen.
- Multiplace Chamber: This larger chamber is designed for several people at once. Inside, each person receives oxygen through a soft, see-through hood or a special mask.
Pressure Changes
As the oxygen fills the chamber, the air pressure slowly increases, similar to the feeling during an airplane takeoff or diving underwater. A soft hissing sound may be heard. Ears may feel full or clogged. To reduce the pressure in the ears, simple actions like yawning, swallowing, or gently blowing while holding the nose closed can help.
Activities
To stay relaxed during treatment:
- In a monoplace chamber, it is possible to watch a movie, listen to music or audiobooks, sleep, or simply rest.
- In a multiplace chamber, additional activities are allowed, such as reading books or playing card games with others.
These activities help pass the time, as treatments may last 1.5 to 2 hours.
Monitoring
A trained healthcare professional watches the entire treatment from outside the chamber. They check the patient’s condition regularly and are always ready to help or answer questions. During longer sessions, short breaks may be given where normal air is breathed instead of oxygen, to keep the treatment safe and comfortable.
After Hyperbaric Oxygen Therapy
Depressurization
After the therapy session ends, the pressure inside the hyperbaric chamber is slowly reduced. This step is called depressurization. It helps the body safely adjust back to normal air pressure, just like coming up slowly from deep water. It is done gradually to avoid any discomfort in the ears or body.
Post-Session Check
Once the chamber returns to normal pressure, a healthcare provider removes the oxygen mask or hood. Then, a quick health check is done. This includes checking blood pressure, heart rate, ear condition, and sometimes blood sugar levels, especially for those with diabetes. These checks help make sure the body has responded well to the treatment.
Departure
After the health check is complete, the person can change out of the treatment clothing and prepare to leave. There is no need to stay in the clinic unless further observation is required.
Post-Session Feeling
Some people may feel a little sleepy or tired after the session. This is normal. Most people can drive home safely, but it might be helpful to have someone else drive, especially for the first session or if feeling extra tired.
Benefits of Hyperbaric Oxygen Therapy
Promotes Healing
Hyperbaric oxygen therapy helps the body heal wounds faster by increasing the amount of oxygen delivered to the injured tissues. This extra oxygen encourages the growth of new skin, blood vessels, and connective tissues, which are all important for repairing wounds and improving recovery.
Safe
This therapy is very safe when it is done by skilled healthcare professionals in approved medical facilities. The controlled environment and expert supervision help ensure that patients receive treatment without serious risks or side effects.
Chronic Wound Benefits
Hyperbaric oxygen therapy is especially helpful for chronic wounds—those that do not heal easily or take a long time to recover. By improving oxygen supply, it supports the healing process in wounds that have become difficult to treat with regular methods.
Risks of Hyperbaric Oxygen Therapy
Claustrophobia
Hyperbaric oxygen therapy often uses monoplace chambers, which are small, enclosed spaces. This can cause feelings of anxiety or panic attacks in some people. To help, doctors may prescribe mild sedatives to reduce discomfort during treatment.
Middle Ear Injuries
During HBOT, pressure changes can affect the ears, causing pain or earache. Sometimes, this leads to bleeding in the ear muscles, fluid buildup, or even a rupture of the eardrum. Careful monitoring is important to avoid or manage these issues.
Sinus Congestion
Pressure changes in the hyperbaric chamber can cause sinus problems such as a runny or stuffy nose, drainage behind the nose, or sinus headaches. These symptoms are usually temporary but can be uncomfortable.
Temporary Nearsightedness
About 20-40% of people who undergo 20 or more daily HBOT sessions may experience temporary nearsightedness (difficulty seeing far). This side effect is more common in older adults and people with diabetes but usually goes away completely after treatment ends.
Oxygen Poisoning (Toxicity)
Though rare, breathing too much oxygen during HBOT can harm the lungs. Symptoms include coughing and shortness of breath. In very severe cases, oxygen poisoning can be life-threatening.
Seizures
Another rare but serious side effect is oxygen-induced seizures. This can happen if the brain gets too much oxygen. A seizure may involve muscle jerking, loss of consciousness, or strange sensations. These seizures are not linked to epilepsy and usually stop when the oxygen levels return to normal. Medical staff closely watch for this and stop the treatment if any early signs appear.
Temporary Vision Changes
Besides nearsightedness, some people might notice other vision changes, such as blurred or double vision. These effects are usually temporary and improve after treatment is completed. Regular eye checks may be recommended for people who need many sessions.
Cost and Accessibility
Hyperbaric oxygen therapy is expensive, and not all hospitals or clinics have the equipment. Some insurance companies may not cover the full cost, especially if HBOT is used for wounds that are not considered life-threatening. This limits access to the therapy, especially in rural or low-resource areas.
Complementing Advanced Healing with Our Medical Dressings
The medical dressings offered through private-label manufacturing are not just basic wound covers. These dressings can be used together with advanced treatments like Hyperbaric Oxygen Therapy (HBOT) or used on their own for mild to moderate wounds. They are flexible, effective, and suitable for both hospitals and home care settings.
One of the key products is the Skin Healing Solution, a medical dressing made from Ganoderma, a natural mushroom known for its healing properties. Whether a patient is undergoing HBOT or not, this dressing plays an important role in supporting healing and is a strong part of a complete wound care plan.
These dressings are designed to enhance healing, whether they are used with HBOT or as the main form of care:
Sustaining the Healing Environment
After HBOT sessions, wounds still need to stay moist to heal well. These dressings help keep the wound moist, which allows cells to grow and repair tissue faster. The dressing helps prevent the wound from drying out, which is important for ongoing healing.
Enhanced Infection Prevention
While HBOT works deep in the body to kill infection, the dressing protects the wound surface. Thanks to Ganoderma Lucidum Chitosan, it gives constant antimicrobial protection, stopping bacteria from causing new infections. This helps keep the wound clean and improves the overall result of both HBOT and regular wound care.
Promoting Tissue Regeneration
The dressing also supports the growth of new tissue. It encourages the development of granulation tissue (new connective tissue and tiny blood vessels) and epithelial cells (cells that cover and protect the wound). When used with HBOT, it helps close wounds faster by working together with oxygen-based healing.
Managing Exudate Effectively
Wounds often produce fluid (exudate), which can increase or decrease depending on the treatment. These dressings come in gel, spray, and sheet mask forms that handle different levels of exudate. This protects the surrounding skin from getting too wet or soft (maceration), which can delay healing.
Biocompatible & Gentle for Fragile Skin
People with wounds, especially those in HBOT care, may have sensitive or damaged skin. These dressings are made from plant-based chitosan and are hypoallergenic (unlikely to cause allergic reactions). They do not contain heavy metals and are safe, gentle, and comfortable for regular use.
Businesses can partner to create their own branded line of medical dressings that match advanced healing methods like HBOT. These dressings offer powerful, ongoing support for patients dealing with chronic or complex wounds. Contact the team to develop a product line that makes a real difference in wound care.
