Hyperbaric oxygen therapy creates a healing environment that is effective in saving the limbs of people with diabetes, healing wounds, saving damaged tissue and reversing the effects of exposure to life-threatening events such as air-gas embolisms.  Mayo Clinic in Rochester has been the home of the largest rectangular chamber in United States since 2007. The new rectangular hyperbaric therapy suite rooms look and feel much like any other room. Patients undergoing hyperbaric oxygen therapy enjoy natural light, an audio-video entertainment system, and may read or visit with other patients during their treatment. The facility also includes dressing rooms, four exam rooms and a smaller chamber to accommodate one person.
