What it is
Hyperbaric oxygen therapy (HBOT) involves breathing oxygen inside a chamber where the air pressure is higher than normal. The idea is that higher pressure allows the blood to carry more dissolved oxygen to tissues. Oxygen is one of many things the body uses when it repairs tissue.
Chambers come in different designs. Some are larger rooms that fit several people and some are single-person units. Treatment is typically given in a hospital or a dedicated wound care or hyperbaric center, supervised by trained staff.
In the United States, the FDA has cleared hyperbaric oxygen for a defined list of indications. In wound care these generally include certain diabetic foot ulcers, radiation-related tissue injury, and certain serious infections. It is not appropriate or cleared for every wound, and only a licensed clinician can decide whether it fits a particular person.
How it’s traditionally been approached
Hyperbaric oxygen has long been used in medicine for conditions where tissue is not getting enough oxygen or where infection is severe. In wound care it has usually been considered an add-on to other care rather than a stand-alone solution.
Wound care teams commonly look at the whole picture first: the cause of the wound, blood flow, infection, pressure, nutrition, blood sugar, and how the wound has been healing. Cleaning and removing unhealthy tissue, dressings, offloading pressure, and compression are examples of approaches that may be part of that picture.
Hyperbaric therapy is typically considered when a wound meets certain criteria, often after other care has been tried for a period. Coverage rules and criteria vary by payer and by the specific condition, so it is worth asking about them directly.
How the right wound care specialist may help
A wound care specialist or hyperbaric physician may start with an evaluation of your wound and health history. They may ask about how the wound started, how long it has been present, your medical conditions, and any medicines you take. They may also check circulation and look for signs of infection. This helps determine whether hyperbaric oxygen is even a possibility for you.
If it is considered, the provider can explain what sessions are generally like, including how the chamber feels, how long a visit may take, and what safety checks are done. They can also describe possible side effects and who may not be a good candidate. Those details are individual and should come from your own clinician.
Good questions to ask include: What is causing my wound, and how is it staged? Is hyperbaric oxygen an FDA-cleared option for my condition? What other treatment options exist? What is the expected healing time? How will progress be measured? What will insurance cover, and is prior authorization needed? If you are also curious about skin substitutes or amniotic products, ask about their regulatory status, since it varies by product.
The whole-person view
Healing is not only about the wound itself. Stress, poor sleep, pain, and worry can affect how the body feels and how well someone is able to keep up with care routines, and a slow-healing wound can in turn add to stress. Body, mind, and daily life influence one another.
Some people find that body-based support such as Somatic Experiences helps them feel more settled while dealing with a long recovery. Others find talk therapy through Therapists.plus useful for coping with the frustration or anxiety that can come with chronic wounds. These are supportive options to discuss alongside, not instead of, medical care.

Keep in mind
- Only a licensed clinician can decide whether hyperbaric oxygen is appropriate for you after an evaluation; this page is not medical advice.
- Seek medical care promptly for spreading redness, red streaking, increasing warmth or pain, pus, foul odor, fever or chills, or a wound that is quickly getting worse.
- Call 911 or go to the ER for heavy bleeding, exposed bone or tendon, signs of sepsis, or a deep or severely contaminated wound. If you are in emotional crisis, call or text 988.
- Hyperbaric oxygen is cleared only for specific indications, results are never guaranteed, and insurance coverage varies, so ask your provider about your wound's cause, staging, options, healing time, and coverage.

Frequently asked questions
What is hyperbaric chamber wound care?
Hyperbaric chamber wound care is the use of hyperbaric oxygen therapy, in which a person breathes oxygen in a pressurized chamber, as part of a wound care plan. It is generally used alongside other wound care, not in place of it. A licensed clinician decides if it is appropriate.
What wounds can hyperbaric oxygen therapy be used for?
The FDA has cleared hyperbaric oxygen for specific indications, which in wound care generally include certain diabetic foot ulcers, radiation tissue injury, and certain serious infections. It is not cleared for every type of wound. A wound care specialist can tell you whether your situation fits.
Is a hyperbaric chamber safe?
Hyperbaric treatment is delivered under trained supervision, but like any medical treatment it has possible risks and is not right for everyone. Your provider will review your health history and explain potential side effects before recommending it. Ask them about safety for your specific situation.
How long does hyperbaric wound treatment take?
The length of a course and of each session depends on the condition and the clinician's judgment, so it varies from person to person. Ask your provider about the expected schedule and healing time for your wound. No one can guarantee how a wound will respond.
Does insurance cover hyperbaric chamber wound care?
Coverage depends on the payer, the diagnosis, and whether certain criteria are met, so it differs from person to person. Many plans require documentation or prior authorization. Ask your provider's office and your insurer what applies to you.
How do I find a hyperbaric wound care specialist?
Start by asking your primary care provider or current wound care clinician for a referral, or look for a licensed provider or hospital-based wound center that offers hyperbaric services. Directories like WoundKare and Providers.plus can help you explore options. Confirm credentials and ask about evaluation, safety, and coverage before starting.
