The blood pressure of.1 of pathology physiology mechanism that SAS causes CVD breathes time-out to be able to bring about airframe in elevatory Morpheus anoxic, sympathetic is excessive and excited, element of serous catechu phenolic amine, kidney and hemal endodermis element are elevatory, bring about hemal easy of hemal convulsion; to shrink the function is disorder, can make blood-vessel flowing flesh happening reframes and fleshy, systemic blood-vessel obstruction adds element of the kidney when; is chronic and anoxic, system of hemal and nervous element is activationed, bring about blood pressure to lift. Obstruction of way of energy of life of patient of OSAS of disease of blood of 1.2 low oxygen increases, cause air current to interrupt, breath pauses, at the same time airframe gets used to low oxygen environment gradually, breathing centre drops to low oxygen and sensitivity of disease of blood of tall carbonic acid, breath suspends a frequency increasing, farther aggravating airframe is anoxic. 1.3 heads are self-adjusting the function drops normal person changes quickly in systematic circulation blood pressure when, the head can be passed adjust independently functional generation protects effect, make change of cerebral blood flow not big.
