The term hyperbaric literally means higher pressure. HBOT involves breathing 100% oxygen while within a treatment chamber that has been pressurized to a pressure higher than sea level. This type of therapy has various potential mechanisms of action, the most important of which is its ability to increase partial pressure of oxygen in the tissues of the body to a degree several times greater than that which can be achieved by breathing pure oxygen at a normal atmospheric pressure. HBOT highly increases the amount of oxygen in blood plasma, which has greater bioavailability to the tissues than does oxygen in hemoglobin. HBOT helps your immune system fight bacteria and generate stem cells which are special cells in your body that help create other types of important cells, including blood cells, brain cells and muscle cells. To benefit from hyperbaric oxygen therapy, you’ll likely need more than one session. The number of sessions depends upon your medical condition.
