呼吸衰竭是由于呼吸功能严重障碍,以至人在静息呼吸空气的情况下不能维持正常的动脉血氧和二氧化碳分压。临床上分为代偿性和失代偿性呼吸衰竭。前者是指虽有缺氧和/或二氧化碳潴留,但在呼吸空气的情况下仍可以维持日常的基本生活;后者是指一定的诱因作用下发生严重的缺氧和二 Respiratory failure is due to severe respiratory dysfunction, so that people can not maintain normal arterial oxygen and carbon dioxide partial pressure in the case of resting breathing air. Clinically divided into compensatory and decompensated respiratory failure. The former means that despite the lack of oxygen and / or carbon dioxide retention, but in the case of breathing air can still maintain the basic daily life; the latter refers to the role of a certain incentive to severe hypoxia and two
