简述心肺复苏第一阶段处置的第一个ABCD步骤。

答案

参考答案:

心肺复苏的步骤是A(airway)开放气道:心搏呼吸骤停患者通常存在一定程度的气道阻塞。首先可用手法开放气道,常用的是三步气道开放法。三步法气道开放是指抬首(头后仰)、举颏(抬下颌)、张口三步。具体操作如下:患者取仰卧位,用双手四指放于患者下颌角处,使头后仰并抬起下颌,拇指放于口角处使口轻度张开。B(breathing)正压通气:开放气道后,检查患者有无自主呼吸。若无自主呼吸,应立即进行口对口人工呼吸,使肺吹张。C(circulation)胸外心脏按压:呼吸循环骤停诊断成立后,应尽早建立有效的人工循环。有效的心脏按压能维持心脏充盈和搏出,诱发心脏的自主性搏动,并可能预防生命重要器官(如脑)因较长时间的缺血缺氧而导致的不可逆性改变。心脏按压分胸外心脏按压和开胸心脏按压两种。D(deftbrillation)电除颤。早期除颤在心搏呼吸骤停患者的复苏中占有重要地位。这类患者能存活的要素包括:①医护人员及时到达现场。②尽早心肺复苏。③尽早除颤。
