Still other signs include, pale or reddish blue skin color. It can be brought in by emotional upsets or exposure to cold. These problems are all caused by the reduction of blood flow in the effected limb. HBOT helps patients with PVD in several ways, The use of HBOt leads to the development of new capillaries, tiny blood vessels linking arteries and veins. This allows a greater amount of oxygen to be delivered to the affected tissue, which in turn, results in more oxygen being absorbed by the tissues.
Hypoxia is relieved and the swelling decreases.
Also HBOT forces oxygen into the blood plasma and the lymph, which normally do not carry oxygen. This dissolved oxygen is more readily used by the body that the oxygen that is normally carried by the red blood cells. That s because oxygen carried in fluid is immediately available to the body s cells, while oxygen in the red blood cells requires the use of energy t make it available. As a result the additional oxygen, the tissues function more normally. The effects of HBOT can readily be seen in the way the patients skin and nail beds steadily turn pink or red in color.
