Mayo Clinic's approach

Your hyperbaric oxygen therapy at Mayo Clinic is based on your doctor getting to know you and understanding your health issues. Together, you'll define a comprehensive whole-person treatment plan to address your needs.

Types of conditions treated

Hyperbaric oxygen therapy is used for three main circumstances:

  • Lifesaving. Hyperbaric oxygen therapy can save the lives of people with air or gas embolisms, decompression sickness, or carbon monoxide poisoning.
  • Limb saving. It can be an effective treatment for nonhealing wounds of people at risk of losing a limb or who have had a crush injury.
  • Tissue saving. It can help repair tissue damage caused by burns, help heal muscle and skin grafts, and treat severe infections.

At Mayo Clinic, hyperbaric oxygen therapy is typically delivered in a large, rectangular chamber with up to three times the normal air pressure. While in the chamber, you receive 100 percent oxygen through a lightweight hood. You are assisted by a nurse.

Hyperbaric oxygen treatments usually last about 90 minutes. The chamber is equipped with an entertainment system to make your treatment relaxing. The number of treatments you receive depends on your condition. Some people may require as few as two or three sessions for conditions like carbon monoxide poisoning or up to 40 sessions for nonhealing wounds.
