What is hyperbaric oxygen therapy?
You rest. You breathe.
Oxygen does the work.
Inside our chamber, gentle pressure lets your blood carry many times more oxygen than normal — reaching injured tissue that ordinary breathing can't. Over a course of relaxed 60–90 minute sessions, that extra oxygen helps your body grow new blood vessels, fight infection, and heal.
