Hyperbaric Oxygen Therapy (HBOT) is a non-invasive method that
consists of supplying oxygen at high concentrations in a pressurized
hyperbaric chamber at a minimum of 1.3 ATM atmospheres (higher than
the normal ambient atmospheric pressure of 1 atmosphere).
Inside the chamber you breathe close to 100% oxygen which is
transported to the blood and manages to reach even the damaged
cells.
