hyperbaric therapy how long
Side effects and possible complications of HBOT. During HBOT, you lie on a table in an enclosed chamber and breathe oxygen while the pressure inside the chamber is gradually increased. The therapy may last as little as 3 minutes or as long as 2 hours before the pressure is returned to normal levels. Because the pressure is so high, some people may have discomfort while in the chamber. You may have ear pain or a popping sensation in the ears.
