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.
SAS诱发CVD的病理生理机制。1血压升高睡眠中呼吸暂停可导致机体缺氧,交感神经过度兴奋,血浆儿茶酚胺、肾素以及血管内皮素升高,导致血管痉挛;血管舒缩功能紊乱,可使血管平滑肌发生重构和肥厚,全身血管阻力增加;慢性缺氧时肾素—血管紧张素系统被激活,导致血压升高。1.2低氧血症OSAS患者气道阻力增加,造成气流中断、呼吸暂停,同时机体逐渐适应低氧环境,呼吸中枢对低氧和高碳酸血症敏感性下降,呼吸暂停次数增加,进一步加重机体缺氧。1.3脑自动调节功能下降正常人在体循环血压快速变化时,脑可通过自主调节功能产生保护效应,使脑血流量变化不大。

It is thought that the advantages of this method are:①dialyze completely beause of the volume of blood flow up to 200 to 300ml per minute ,②affect cardiovascular system alighily beause of blood flow form vien to vein during the pocess of hemodialysis ,③keep patients moving freely,and ④indwell catheter several weeks.
作者认为锁骨下静脉双胜留置导管血液透析的优点很多,首先,血流量可达200~300ml/min,能保证充分透析;另一方面透析时血液循环是静脉到静脉,对心血管系统影响小;该部位插管病人活动不受限,且导管留置时间可长达数周,所以不仅可作和临时性血透通路,也可作为长期维持性血液透析的血透通路。
