Hyperbaric oxygen therapy treats chronic wounds, diabetic foot ulcers, bone infections, and more
Hyperbaric oxygen therapy (HBOT) is a treatment that involves breathing almost pure oxygen in a special room or small chamber. The air we typically breathe contains 21% oxygen, but HBOT delivers 100% oxygen in a pressurised environment, increasing the amount of oxygen in the blood. This extra oxygen can help to repair tissues and restore the body's normal functioning.
HBOT is an effective treatment for chronic wounds, diabetic foot ulcers, and bone infections. Diabetic foot ulcers are a common complication of diabetes, affecting 15-25% of people with the condition. The high blood sugar levels associated with diabetes can slow wound healing, and foot ulcers can be challenging to treat due to antibiotic resistance and the body's compromised immune system. HBOT has been shown to improve the healing process for these wounds, reducing the risk of serious adverse events such as amputation and infection.
In addition to treating diabetic foot ulcers, HBOT is also beneficial for individuals with chronic bone and soft tissue damage caused by radiation therapy for cancer. The radiation can damage tiny blood vessels, and HBOT helps to promote the growth of new blood vessels in these affected areas.
While HBOT is a valuable treatment option for certain conditions, it is not a cure-all. Some patients may mistakenly believe that HBOT can treat cancer, Parkinson's disease, or Alzheimer's disease, but these are non-evidence-based uses. It is important to follow the guidance of medical professionals when considering HBOT as a treatment option.
In the United States, an estimated 1,800 to 2,000 hospitals offer HBOT, with an additional 500 to 700 non-hospital-based programs providing this treatment. Most hospitals use monoplace chambers designed for single-person use, while some facilities have larger chambers that can treat multiple people simultaneously.

It can be administered in mono or multiplace chambers
Hyperbaric oxygen therapy (HBOT) can be administered in mono or multiplace chambers. Monoplace chambers are designed for a single patient and are typically made of clear acrylic. They are small, cost-efficient, and easy to install, requiring less staffing and no inside attendant. During treatment, the chamber is pressurized and filled with 100% oxygen, which the patient breathes normally without the need for a hood or mask. Monoplace chambers are generally found in outpatient centres and non-hospital-based programs.
On the other hand, multiplace chambers are very large and can accommodate multiple patients at once. They are commonly found in hospitals, where medical teams can easily access the chamber as needed. These chambers allow for the presence of lifesaving medical equipment inside and are ideal for treating critically ill patients with failing vital functions and organ systems. In a multiplace chamber, the entire room is pressurized to the same depth, and patients wear a hood or mask to breathe in oxygen.
The choice between mono and multiplace chambers depends on the clinical indications and required hyperbaric treatment protocols. Monoplace chambers offer advantages such as cost-efficiency and patient comfort due to the absence of a hood or mask. However, they may present challenges in maintaining standard organ support and invasive monitoring, and they require the use of muscle relaxants and excessive sedation. In contrast, multiplace chambers are better suited for treating critically ill patients as they allow for the use of ICU equipment inside the chamber, but they may cause discomfort due to the enclosed space and the use of hoods or masks.
Both mono and multiplace hyperbaric chambers are deemed medical grade and are FDA-approved for treating multiple medical conditions.

Hospitals offering hyperbaric oxygen therapy have increased
Hyperbaric oxygen therapy uses a special pressure chamber to increase the amount of oxygen in the blood. This therapy can help heal traumatic injuries and wounds, particularly infected wounds, by promoting the growth of new blood vessels in areas ravaged by disease. It is also used to treat bone infections, burns, carbon monoxide poisoning, and compromised skin grafts.
An increasing number of hospitals are offering hyperbaric oxygen therapy. According to John Peters, executive director of the Undersea and Hyperbaric Medicine Association, an estimated 1,800 to 2,000 hospitals in the United States offer this treatment. This number has likely increased since Peters' statement in 2014. In addition, about 500 to 700 non-hospital-based programs offer hyperbaric oxygen therapy. The increase in the number of hospitals offering this treatment may be due to the growing recognition of its benefits. For example, Dr. Henricks, who has been using hyperbaric oxygen therapy for 11 years, says the "results were tremendous."
However, it is important to note that hyperbaric oxygen therapy is not a cure-all. While it has shown positive outcomes in treating traumatic brain injuries, its use in this area is still considered "investigational." Additionally, concerns have been raised about unauthorized and non-medically necessary uses of the treatment. As a result, the Centers for Medicare and Medicaid Services (CMS) implemented a prior authorization program in Illinois, Michigan, and New Jersey to address these concerns.
Despite the increasing availability of hyperbaric oxygen therapy in hospitals, there is a shortage of facilities offering emergency HBO2 treatment. As of 2024, fewer than 10% of the approximately 1,300 U.S. hyperbaric facilities accept emergency HBO2 patients, a significant decline from two decades ago when most facilities offered this service. This shortage has led to treatment delays, which can negatively impact patient outcomes, especially in cases of decompression sickness or arterial gas embolism.
To summarize, while more hospitals are offering hyperbaric oxygen therapy, the decline in facilities providing emergency HBO2 treatment is a cause for concern. This deficiency in the U.S. healthcare system has been recognized by organizations such as the Undersea and Hyperbaric Medical Society, who are advocating for change.

It is not a cure for cancer, Parkinson's, or Alzheimer's
Hyperbaric oxygen therapy (HBOT) is a treatment method where patients breathe pure oxygen in a pressurised environment, which significantly boosts the amount of oxygen in their bloodstream. This treatment is available in many hospitals and is used to treat a wide range of medical conditions. However, it is important to note that it is not a cure for cancer, Parkinson's disease, or Alzheimer's disease.
While HBOT has been shown to have some positive effects on patients with these diseases, it does not cure them. Some patients mistakenly believe that HBOT can cure cancer, Parkinson's, and Alzheimer's, but these are non-evidence-based uses for this therapy, as stated by Dr Timothy Manoni, medical director of the Wound Care and Hyperbaric Center at Stamford Hospital in Connecticut.
In the case of cancer, HBOT can help heal chronic bone and soft tissue damage caused by radiation treatment. It does this by promoting the growth of new blood vessels in the affected areas. However, it does not cure the cancer itself.
For Parkinson's disease, there is some controversy over the use of HBOT as an "off-label" treatment that hasn't been approved by the FDA. While some experts believe patients should only receive these treatments if they are participating in a research study, others argue that HBOT could be used to dramatically reduce pain and suffering. However, there is no evidence that HBOT cures Parkinson's disease.
Regarding Alzheimer's disease, HBOT has been found to improve cerebral blood flow and cognitive function in elderly patients with significant memory loss. It has also been shown to reduce the volume of amyloid plaques, which are a hallmark of Alzheimer's. While this treatment may slow or even prevent the development of Alzheimer's, it is not a cure. The effectiveness of HBOT is most pronounced in the early stages of Alzheimer's, and it is recommended as a treatment for managing the condition.

Fewer hyperbaric treatment facilities offer emergency HBO2 treatments now
Hyperbaric oxygen therapy (HBOT) is a medical treatment in which a patient breathes 100% oxygen inside a pressurised chamber. The therapy increases the amount of oxygen in the blood, helping to heal traumatic injuries and wounds, particularly infected wounds. It is also used to treat bone infections, burns, carbon monoxide poisoning, and compromised skin grafts.
While HBOT is a widely recognised treatment, with the American Board of Emergency Medicine (ABEM) and the American Board of Preventive Medicine (ABPM) acknowledging it as a subspecialty, there has been a recent decline in the number of hyperbaric treatment facilities offering emergency HBO2 treatments. This decline may be due to several factors, including the specialised nature of the treatment and the need for specialised equipment and training.
One factor contributing to the decline in emergency HBO2 treatments is the strict regulations surrounding the therapy. In the United States, the U.S. Food and Drug Administration (FDA) and the Undersea and Hyperbaric Medical Society (UHMS) have established specific indications for the use of hyperbaric oxygen therapy. These indications are scientifically validated and must be followed by hospital-based programs. Non-hospital-based programs offering off-label treatments may face government concerns about unauthorized uses of the treatment, as mentioned by the Centers for Medicare and Medicaid Services (CMS).
Another factor is the specialised equipment required for HBO2 treatments. Most hospitals have monoplace chambers, which are designed for single-person use. While some facilities have larger chambers that can treat multiple people at once, the equipment is still costly and requires specialised training to operate. This may limit the number of facilities that can offer emergency HBO2 treatments.
In addition to the equipment and regulatory factors, the decline in emergency HBO2 treatments may also be attributed to the time-sensitive nature of the therapy. Data suggests that optimal benefits from HBO2 treatments occur with minimal delay after exposure to carbon monoxide poisoning. This requires quick access to hyperbaric chambers, which may not be feasible for all patients or facilities.
Furthermore, the specialised staff required to operate the chambers and provide the therapy may also contribute to the decline in emergency HBO2 treatments. Hyperbaric oxygen therapy is a complex treatment that requires trained professionals to ensure patient safety. The limited availability of these specialists may impact the ability of facilities to offer emergency treatments.

Frequently asked questions
Not all hospitals have a hyperbaric chamber. An estimated 1,800 to 2,000 hospitals offer hyperbaric oxygen therapy in the US, and about 500 to 700 non-hospital-based programs offer the treatment.
Hyperbaric oxygen therapy is used to treat serious conditions, including chronic wounds, diabetic foot ulcers, radiation injury, bone infections, burns, carbon monoxide poisoning, and compromised skin grafts. It can also be used to treat decompression sickness, also known as "the bends", which can affect divers who surface too quickly.
During hyperbaric oxygen therapy, patients are asked to wear a medical gown and lie on a table that slides into a clear plastic tube. The chamber is then sealed and filled with pressurized oxygen, with pressure rising to 2.5 times the normal air pressure. Patients are advised to relax and breathe normally, and they can watch TV or listen to music during the procedure.
You might feel pressure in your ears while you are in the hyperbaric chamber, and your ears may pop when you get out, similar to what happens when you are on a plane.
There are concerns about the unauthorized and non-medically necessary use of hyperbaric oxygen therapy. Some patients believe it can cure conditions such as cancer, Parkinson's disease, and Alzheimer's disease, but these are non-evidence-based uses. Additionally, there is a decline in the number of facilities offering 24/7 emergency hyperbaric oxygen therapy due to funding, staffing, and liability issues.
