Calciphylaxis is a rare condition that usually occurs in people with kidney disease. Excess calcium builds up in the patient's arteries and blood vessels, and the result is blood clotting, exacerbating skin damage and causing extreme pain.

Calciphylaxis is a very serious disease with a high mortality rate. In Medical News Today, hyperbaric oxygen is listed as a potentially beneficial treatment for those suffering from calcification trauma.

—Hyperbaric oxygen therapy can promote wound healing. It involves exposing the wound to a much higher pressure of oxygen than usual. This helps speed up the healing process.

—A 2015 analysis concluded that the therapy benefited more than half of the people they evaluated. It has also been suggested that this could increase a person's life expectancy.
