Hyperbaric oxygen therapy (HBOT), as administered at he Mount Rainier Clinic, is a medical treatment during which the entire body is placed in a transparent, airtight chamber at increased atmospheric pressure. The patient is surrounded by and breathes 100 percent pure oxygen. This treatment is proven effective for a number of different medical and surgical conditions either as a primary or adjunctive treatment. It is also used to treat many other medical conditions that are still considered experimental by the mainstream medical establishment—despite decades of reported benefit.

At Mount Rainier Clinic in Yelm, Washington (near Tacoma and Olympia), we utilize Sechrist monoplace hyperbaric chambers. They are large enough to hold a seven-foot patient. The pressure can be increased to as much as three times normal atmospheric pressure (although the usual treatment pressure is twice atmospheric or less). Pure, 100 percent oxygen is continuously maintained and circulated throughout the treatment. There is no need to wear a mask or hood at our clinics because the entire chamber is pressurized with oxygen instead of room air. This method requires much more oxygen per treatment, but provides additional benefit at lower pressures—especially to areas of the body with poor blood flow.
