呼吸的主要功能是使机体不断地摄入氧和排出多余的二氧化碳,这是保证新陈代谢和各种生命活动正常进行的最根本的条件之一,而完整的呼吸功能包括外呼吸过程、内呼吸过程和血液携带运输氧和二氧化碳的功能。因此,当上述这些环节因各种原因发生障碍时均可引起呼吸功能的障碍。本讲座着重讨论呼吸过程障碍的病理生理学,并对缺氧的一些基本知识作简要的叙述。 Breathing the main function is to make the body continue to intake of oxygen and the discharge of excess carbon dioxide, which is to ensure the normal metabolism and various life activities of one of the most fundamental conditions, and complete respiratory function, including the process of external respiration, endobronchial process And blood to carry oxygen and carbon dioxide transport function. Therefore, when these links for various reasons, obstacles can cause respiratory dysfunction. This talk focuses on the pathophysiology of respiratory disorders and briefly describes some of the basic knowledge of hypoxia.
