What is vasculitis and why can the hyperbaric chamber be useful to treat it?

Vasculitis occurs when there is inflammation in any of the blood vessels of the body (arteries, arterioles, veins, venules or capillaries), which causes the failure or loss of blood flow to the organs or extremities of the body.

What are the causes?

There are several types of vasculitis and possible causes that trigger it. The professionals consider that most of the vasculitis are developed by an autoimmune disease, such as lupus, rheumatoid arthritis or scleroderma, although a patient can coexist for years with this type of autoimmune diseases without contracting vasculitis. Vasculitis can also be caused by a recent or persistent infection, or because the body reacts to a medication by attacking its own blood vessels.

How to recognize it?

Due to the diversity of types of vasculitis, the symptoms are also varied. The patient may have common symptoms, such as fatigue, fever, nausea or weight loss, but there are specific signs that depend on the organ affected by the occlusion of the blood vessels.

How does the Hyperbaric Oxygenation Treatment help patients with vasculitis?

Hyperbaric Oxygenation Treatment (HBOT) is a therapeutic solution for patients with refractory ulcerative vasculitis. The increase of available oxygen in blood:


  • Has bactericidal and bacteriostatic effects that eliminate bacteria and prevent their reproduction and the advance of infections.
  • Facilitates the creation of new blood vessels and the propagation of fibroblasts and endothelial cells, essential for healing.
  • Reduces inflammation and, as a consequence, pain.
  • Stimulates the repair of tissues.
  • Facilitates the transport of oxygen to blood capillaries
  • Increases the effectiveness of antibiotics.
