In addition to antibiotics and surgery, hyperbaric oxygen therapy also may be used to treat gangrene. Under increased pressure and increased oxygen content, your blood is able to carry greater amounts of oxygen. Blood rich in oxygen slows the growth of bacteria that thrive in the absence of oxygen and helps infected wounds heal more easily.
Why is hyperbaric oxygen treatment used for gangrene?
Why is hyperbaric oxygen treatment used for gangrene? Hyperbaric oxygen: Hyperbaric oxygen treatment is a process where a person is placed in a room or chamber with high pressurized 100% oxygen. This delivers high levels of oxygen to the person and can be used to treat slow or difficult to heal wounds like diabetic or infected wounds.
How does hyperbaric oxygen therapy work?
Hyperbaric oxygen therapy uses 2 types of chambers: Monoplace chamber. This is a chamber built for one person. It's a long, plastic tube that resembles an MRI machine. The patient slips into the chamber. It is slowly pressurized with 100% oxygen. Multiplace chamber.
How are antibiotics used to treat gangrene?
Antibiotics that are given through a vein (intravenous), or those that are taken orally, may be used to treat gangrene that has become infected. If you have to have surgery to remove dead tissue, your doctor will probably prescribe certain antibiotics until no further surgery is needed and your infection is cleared.
How many HBO treatments are required for healing of gangrenous lesions?
The number of HBO treatments required for healing was significantly related to the size of gangrenous lesions. In the non-HBO-treated group, only 1 patient improved, 5 of 10 showed no change, and 4 of 10 worsened until leg amputation was unavoidable.
Why is hyperbaric oxygen treatment effective against gas gangrene?
The HBO2 will work by increasing the oxygen levels in the tissues and killing the bacteria that live in the low oxygen environment.
How does hyperbaric oxygen therapy work for wound healing?
During the treatments, the patient breathes 100 percent oxygen inside a pressurized chamber, quickly increasing the concentration of oxygen in the bloodstream, where it is delivered to a patient's wound site for faster healing. Essentially, HBO therapy helps heal the wound from the inside out.
What is the mechanism of action of hyperbaric oxygen therapy?
HBOT has two primary mechanisms of action - Hyperoxygenation and a decrease in bubble size. Hyperoxygenation is an application of Henry's law and results from an increase in dissolved oxygen in plasma as a result of increased partial pressure of arterial oxygen.
What wounds are treated with hyperbaric oxygen therapy?
HBOT is also indicated for infected wounds like clostridial myonecrosis, necrotising soft tissue infections, Fournier's gangrene, as also for traumatic wounds, crush injury, compartment syndrome, compromised skin grafts and flaps and thermal burns.
What are the benefits of hyperbaric oxygen treatment?
Hyperbaric oxygen therapy can increase circulation and oxygenation, Frye adds, allowing the oxygen to build and repair damaged blood vessels, as well as triggering collagen growth, which leads to healing. “The increase in pressure can also reduce swelling, which in turn, increases blood flow,” she says.
How does oxygen therapy work?
It involves breathing oxygen in a pressurized chamber or tube. This allows your lungs to gather up to three times more oxygen than you would get by breathing oxygen at normal air pressure. The extra oxygen moves through your blood and to your organs and body tissues.
What are the benefits of oxygen therapy?

What is the difference between ozone therapy and hyperbaric oxygen?
Hyperbaric oxygen (HBO) treatment is based on the principle of having the patient breath 100% oxygen in an environment above atmospheric pressure. Ozone (O3) is a colourless gas with a specific odour and consists of three oxygen atoms.
How does hyperbaric oxygen therapy work?
Hyperbaric oxygen therapy involves increasing your exposure to pure oxygen in a pressurized room or tube. When you breath inside the hyperbaric chamber, your lungs are able to gather up to three times more oxygen than it would normally, allowing it to enter your blood and promote healing.

HBO2 therapy is most often used to treat wounds caused by diabetes, such as those to the lower extremities, ...
What is the best treatment for decompression sickness?
Hyperbaric oxygen therapy is used to reduce bubbles in the bloodstream and fill the tissues with oxygen. Research shows that HBO2 therapy is recommended for most decompression sickness cases until the patient is stable.
Why does HBO2 cause shortness of breath?
The condition is caused by bubbles of nitrogen and other gasses forming in the bloodstream, leading to severe joint pain, dizziness and shortness of breath. Hyperbaric oxygen therapy is used to reduce bubbles in the bloodstream and fill the tissues with oxygen. Research shows that HBO2 therapy is recommended for most decompression sickness cases ...
How does HBO2 work?
It works to restore the bacteria-killing abilities of white blood cells in wounds by increasing tissue oxygen tensions, and studies show that it even works synergistically with a number of antibiotics. 3. Heals Chronic Wounds.
What is HBOT in medical terms?
Hyperbaric oxygen therapy (HBOT) involves supplying the body’s blood and tissues with pure oxygen in order to promote healing. Hyperbaric medicine was first used in the 1600s when patients went into airtight chambers that could be compressed and decompressed.
What is hyperbaric oxygen therapy?
Hyperbaric oxygen therapy is a treatment where individuals are placed inside a special environment that increases the pressure and pure oxygen. As patients remain in this environment, the pure oxygen perfuses into the blood to help increase the total amount of oxygen. As oxygen supersaturates the blood, it can reach tissues ...
Why does gas gangrene occur?
The infection occurs because of a buildup of bacteria called clostridium. While there are approximately 150 different species of this bacteria, only a few are known to cause gas gangrene. The infection generally begins at a single point in the body but can spread rapidly to adjacent tissues.
Why are hyperbaric chambers effective?
So, why are hyperbaric chambers effective in treating gas gangrene? When doctors and researchers found that clostridium bacteria don’t thrive in oxygenated environments, it was a quick jump to treat patients with hyperbaric oxygen therapy. However, as with most conditions, hyperbaric oxygen therapy is not a standalone treatment plan. While HBOT can help prohibit or reduce the spread of infection, additional treatments are required to help eliminate the infection. In minor cases that were caught early, antibiotics may be the only other intervention. However, because gas gangrene moves so quickly, most patients also require surgery to remove the infected tissue.
What is the most severe form of gangrene?
Gas gangrene is a more severe form of infection because it contains a unique toxin called an exotoxin. Exotoxins liquefy and destroy adjacent healthy tissue. When the infection destroys the tissues, it is then called clostridial myonecrosis. Necrosis refers to the death of a cell.
How to tell if you have gas gangrene?
Because the clostridium bacteria are primarily located in the gastrointestinal tract, surgeries or injuries that occur in this area should be closely watched for infection. The types of surgeries with a higher instance of infection and gas gangrene are operations on the colon or gallbladder. One of the first symptoms of gas gangrene is severe pain in the infected area. Individuals may notice pale skin and swell at the site, but that can quickly turn to red, bronze, and then a blackish green as the infection spreads and kills the cells. Blisters are often associated with gas gangrene, and these blisters can fill with gas bubbles.
What is the role of Clostridium bacteria in anaerobic environments?
Clostridium bacteria are a type of anaerobic bacteria. This means that they prefer and thrive in low oxygen environments. When they are exposed to oxygen-rich environments, their ability to replicate or produce exotoxin is reduced. Learn More.
How long does it take for gas gangrene to go away?
Gas gangrene is 100% fatal for patients who don’t receive treatment and usually occurs within 48 hours. Due to the severity of the infection, a swift and proper diagnosis is critical.
What is the name of the chamber where you breathe 100% oxygen?
HBOT involves breathing 100% (pure) oxygen while in a special space called a hyperbaric chamber. The air pressure inside is raised to a level that is higher than normal air pressure.
What is HBOT in diving?
Hyperbaric oxygen therapy (HBOT) is well known for treating scuba and deep-sea divers affected by the rapid change in pressure around them. But did you know that HBOT is also used to treat a variety of other health problems, including carbon monoxide poisoning and diabetic foot ulcers?
Is HBOT safe?
When HBOT chambers are used for indications cleared by the F DA, HBOT is generally safe, and serious complications are rare.
How does hyperbaric oxygen therapy work?

The treatment for gangrene generally lasts about 90 minutes. You may need two to three treatments every day until the infection clears.
What is the procedure to remove gangrene?
Surgery for gangrene includes: Debridement. This type of surgery is done to remove the infected tissue and stop the infection from spreading. Your doctor may also perform surgery to repair any damaged or diseased blood vessels to restore blood flow to the infected area. Your doctor may prescribe certain antibiotics until the infection is cleared.
What tests are used to diagnose gangrene?
Tests used to help make a diagnosis of gangrene include: Blood tests. An abnormally high white blood cell count is usually a sign of infection. Your doctor might also order blood tests to look for the presence of specific bacteria or other germs. Fluid or tissue culture. Tests of the fluid from a blister on your skin may be examined ...
