心肺复苏按压和放松的比例是为1:1,不是1:2。不必担心释放时间不足影响到回心血量最后导致按压效果不佳,其实对按压效果影响更大的还是按压的深度、频率和按压后是否完全放松这些因素。
心肺复苏应先做心脏按压后再人工呼吸。头偏向一侧,清除口腔内异物。采用仰头抬颌法,复苏全过程保持气道通畅。开放气道时间3秒。口对口人工呼吸:吹气时间1秒,吹气量以胸廓明显上升为准,连续吹气两次。
这一项技术广泛的运用于人们的急救之中,因这项技术而拯救的人数不胜数,通过这项技术拯救了无数人的生命。但据研究表明,不正确的心肺复苏按压放肆会造成患者的二次伤害,甚至可能造成骨折。
扩展资料:
心肺复苏超过 10 min 就可能导致患者肋骨骨折、内脏受损。心脏按压损伤有时是不可避免的,有时等不到按压 10 min,甚至在第一下按压的时候就可能造成骨折。
心脏按压损伤包括胸骨骨折、肋骨骨折、心脏及心包损伤、血气胸、肺脏、肝脏、脾脏及胃肠损伤等。
一旦按压损伤发生,将会影响复苏质量,按压产生的严重损伤有时甚至是直接死因。另外,按压损伤可能授人以柄,引发医患纠纷甚至诉讼。

心肺复苏按压和放松的比例是1:1。每次按压完成后需要让胸廓完全回复。
胸外按压(circulation, C)操作:
确保患者仰卧于平地上或用胸外按压板垫于其肩背下,急救者可采用跪式或踏脚凳等不同体位,将一只手的掌根放在患者胸部的中央,胸骨下半部上,将另一只手的掌根置于第一只手上。手指不接触胸壁(图4)。按压时双肘须伸直,垂直向下用力按压,成人按压频率为至少100次/min,下压深度至少为125px,每次按压之后应让胸廓完全回复。

心肺复苏时进行胸外按压的按压释放比为1:1,而不是1:2。你不必担心释放时间不足影响到回心血量最后导致按压效果不佳,其实对按压效果影响更大的还是按压的深度、频率和按压后是否完全放松这些因素。所以我们强调在进行胸外按压时一定要按足深度,按足频率,并且按压间隙在掌根不离开胸壁的前提下尽可能放松。
