The FDA’s website notes that therapy works by breathing 100% oxygen inside a hyperbaric chamber where the “air pressure inside is raised to a level that is higher than normal air pressure.”

“The increased air pressure in the chamber helps the lungs collect more oxygen. Getting more oxygen to the tissues that need it can help the body heal and fight certain infections,” the website explains. 

Hyperbaric oxygen therapy chambers are cleared by the FDA for use for a variety of disorders, including crush injuries, which Renner suffered earlier this year.
