摘要：The way peripheral blood oxygen desaturation occurs, as evidenced by the oxygen saturation index, is not fully elucidated during both physical exercise and functional tests. The paper presents some physiological influences of physical effort on arterial vasodilation, highlighting the fact that nitric oxide and vasodilation products produced by striated muscles, in the case of individuals with high muscular mass, increased values of the oxygen saturation index can be recorded immediately after the physical exercises. Increased doses of nitric oxide or vasodilator prostaglandins may also occur under the influence of some drugs, and some substances designed to treat migraine are concurrently inhibitors of nitric oxide synthase. In these ways, values of the oxygen saturation index that do not correspond to cardio-respiratory capacity can be recorded during exercise tests.
