口对口吹气式人工呼吸操作方法

答案

参考答案:

病人仰卧,术者位于病人一侧,低头观察病人胸廓无呼吸起伏动作,口鼻亦无气息吐出,颈动脉搏动消失,判断其呼吸心跳停止,呼叫同事抢救的同时,迅速松开其领口和腰带、并抽去枕头,用纱布或手帕清除病人口鼻分泌物及异物,保持呼吸道通畅。一手抬起患者颈部,使其头部后仰,另一手压迫病人前额保持其头部后仰位置,使病人下颌和耳垂连线与床面垂直;一手将病人的下颌向上提起,另一手以拇指和示指捏紧病人的鼻孔。术者仅需平静呼吸,将口唇紧贴病人口唇,把病人嘴完全包住,深而快地向病人口内吹气,时间应持续1秒以上,直至病人胸廓向上抬起。此时,立刻脱离接触,面向病人胸部再吸空气,以便再行下次人工呼吸。与此同时,使病人的口张开,并松开捏鼻的手,观察胸部恢复状况,并有气体从病人口中排出。然后再进行第二次人工呼吸。吹气频率维持在每分钟8~10次。
