HBO consists of administering pure oxygen under pressure. There is oxygen in every breath we take, but only 21% of it. In a hyperbaric chamber, you breathe in 100% oxygen at up to 2 times the normal atmospheric pressure.
The heightened pressure conditions allow the extra oxygen to dissolve in the blood plasma, enabling all areas of the body to become flooded with it, including those where circulation is poor or blocked.
Oxygen is essential to all body tissues, particularly injured ones that require oxygen to heal. Extra oxygenation through HBOT is proven to accelerate the healing process and reduce inflammation. Inflammation in the central nervous system is a signature characteristic of MS, which is one of the reasons why HBOT can retard the progression of the illness. HBOT is also known to boost energy, promote faster recovery from fatigue, reduce pain, and improve concentration and mental clarity, thus alleviating many of the symptoms of MS.
