在施行人工呼吸急救过程中,如果停止人工呼吸过早,可能失去最后一线挽救希望;而不必要的延长人工呼吸,则又毫无意义。因此,到什么程度方可停止施行人工呼吸,是一个重要的实际问题。一般认为停止人工呼吸的指征有二:一是病员恢复了自动呼吸,二是病员确已死亡。人工呼吸的目的在于纠正缺氧及排除二氧化碳。在有效的人工呼吸过程中,病员的缺氧现象多能逐渐被纠正。临床观察可见病员肤色由青紫转为红润,瞳孔由大变小,脉搏由弱转强。在这种情况下,应坚持作人工呼吸至自动呼吸确已恢复为止。
In the implementation of emergency resuscitation of artificial resuscitation, if the resumption of artificial respiration is stopped prematurely, the hope of rescuing last-line rescue may be lost. And it is meaningless to prolong artificial respiration unnecessarily. Therefore, the extent to which artificial respiration can be stopped is an important practical issue. There are two general indications for stopping artificial respiration: one is that the patient resumes automatic respiration, and the other is that the patient has indeed died. The purpose of artificial respiration is to correct hypoxia and eliminate carbon dioxide. In the process of effective artificial respiration, the patient’s hypoxia can gradually be corrected. Clinical observation showed that the patient’s skin color changed from purple to rosy, pupil from big to small, pulse from weak to strong. In this case, insist on artificial respiration until the resuscitation has indeed resumed.
