一、呼吸衰竭的概念任何原因引起肺功能严重损害导致肺泡通气不足或和无法进行有效气体交换,造成机体缺氧并伴有或不伴有 CO_2潴留,引起一系列生理功能紊乱和代谢障碍的临床综合征,称为呼吸衰竭。导致呼衰原因甚多,临床表现错综复杂,病情变化迅速,预后凶险,成为临床上常见的重大课题之一。高原低氧环境对呼衰的发生、发展、预后有着显著的影响,更有其特殊性。呼衰在发生和发展过程中,低氧血症是造成对机体威胁的主要因素;CO_2潴留、酸碱平衡失调,电解质紊乱相续发生,进而对脑、心、肾、肝及肺本身产生不同程度损害或产生血凝障碍。感染可导
First, the concept of respiratory failure For any reason, severe damage to lung function leading to inadequate alveolar ventilation or ventilation and can not be effective, resulting in hypoxia with or without body CO2 retention, causing a series of physiological dysfunction and metabolic disorders in clinical Syndrome, called respiratory failure. Resulting in many causes of respiratory failure, complex clinical manifestations, rapid changes in the disease, the prognosis dangerous, clinically common major issues. High altitude hypoxic environment has a significant impact on the occurrence, development and prognosis of respiratory failure, but also has its own particularity. Respiratory failure in the occurrence and development process, hypoxemia is caused by the main threats to the body; CO_2 retention, acid-base balance disorders, electrolyte disorders continue to occur, and then the brain, heart, kidney, liver and lung itself produces different To the extent of damage or produce hemagglutination. Infection can guide
