Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves breathing pure oxygen in a pressurized chamber. This increased oxygen level can promote healing and tissue repair, making it an effective treatment for certain medical conditions.
In this section, we will explore the FDA-approved uses for hyperbaric oxygen therapy. The FDA, or the U.S. Food and Drug Administration, is responsible for evaluating the safety and efficacy of medical treatments before granting approval.
What are the FDA approved uses for hyperbaric oxygen therapy? Keep reading to find out more about the indications for which HBOT has received FDA approval, and how it can benefit patients.
Understanding Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves breathing pure oxygen in a pressurized chamber. This therapy is believed to help increase the amount of oxygen in the body, which can promote healing and tissue repair.
During hyperbaric oxygen therapy, the patient enters a specially designed chamber that is pressurized to levels greater than the atmosphere. The patient then breathes pure oxygen through a mask or hood. This increased pressure and oxygen level can help deliver more oxygen to the body’s tissues, which can promote healing.
Research has shown that hyperbaric oxygen therapy can have a variety of potential benefits. These include:
- Improved oxygenation: The increased oxygen delivered to the tissues during HBOT can help promote healing and recovery.
- Reduced inflammation: HBOT may help reduce inflammation by reducing the size of swollen blood vessels.
- Enhanced wound healing: HBOT may improve the healing of wounds by promoting the growth of new blood vessels.
FDA Approval Process for Hyperbaric Oxygen Therapy
The US Food and Drug Administration (FDA) carefully evaluates medical treatments before granting approval for their use in patients. Hyperbaric oxygen therapy (HBOT) is no exception.
The FDA approval process involves several steps, including laboratory and animal studies, clinical trials, and review of the treatment’s safety and effectiveness. The manufacturer of the treatment must submit an application to the FDA, which is then evaluated by a team of experts before a decision is made on whether to approve the treatment.
For HBOT to be FDA approved, scientific evidence must demonstrate that the therapy is safe, effective, and has a favorable benefit-to-risk ratio. The FDA evaluates data from clinical trials and reviews the treatment’s mechanism of action, potential side effects, and long-term outcomes. If the treatment meets the FDA’s standards for safety and efficacy, it may be approved for use in certain patients or conditions.

How Does Hyperbaric Oxygen Therapy Work for These Indications?
The exact mechanism of action for hyperbaric oxygen therapy varies depending on the indication being treated. However, in general, HBOT works by increasing the amount of oxygen delivered to tissues, which promotes healing and tissue repair. By increasing oxygen levels, HBOT can also reduce inflammation, stimulate the growth of new blood vessels, and enhance the body’s natural immune response.
For example, in the case of decompression sickness, HBOT works by reducing the size of the bubbles that form in the bloodstream, allowing them to be reabsorbed by the body. In the case of diabetic foot ulcers, HBOT can enhance wound healing and reduce the risk of infection by promoting the growth of new blood vessels and increasing oxygen supply to the affected area.
Treating Decompression Sickness with Hyperbaric Oxygen Therapy
Decompression sickness, also known as the bends, is a condition that can occur when a person experiences rapid changes in pressure, such as when ascending from a deep dive. This condition can cause gas bubbles to form in the bloodstream, resulting in symptoms such as joint pain, fatigue, and skin rash. In severe cases, the bends can be life-threatening.
Hyperbaric oxygen therapy has been shown to be an effective treatment for decompression sickness. The therapy involves placing the patient in a pressurized chamber and administering pure oxygen at a higher pressure than normal atmospheric pressure. This increased oxygen level can help to reduce the size of gas bubbles in the bloodstream, allowing them to be safely absorbed by the body.
Hyperbaric oxygen therapy can also promote the healing of damaged tissues caused by decompression sickness. By increasing oxygen delivery to affected areas, the therapy can help to reduce inflammation and promote tissue repair. In addition, HBOT can help to alleviate symptoms such as joint pain and fatigue, enabling patients to recover more quickly.
How does hyperbaric oxygen therapy benefit individuals with decompression sickness?
|Reduces gas bubble size||HBOT can help to reduce the size of gas bubbles in the bloodstream, allowing them to be safely absorbed by the body.|
