人的生命所以能够存活,主要是靠生理性的氧合作用.氧合作用简单地说,就是心脏搏动所造成的血液循环和由肺呼吸造成的氧气和废气的交换过程.任何一种“假死”现象都是中断了这一过程的进行.我们可以采用人工的方法来暂时代替已经停止的生理性氧合作用,以求过渡到正常功能的复苏,这就叫做人工心肺复苏急救法.人工心肺复苏急救法,就是完成人工氧合的过程,分为两个方面:一是口对口(鼻)人工呼吸,使肺部扩张和收缩,吸进氧气供到血液里;二是胸外心脏挤压,使心脏发挥“泵”作用,把含氧的血液送到大脑和全身.两种方法联合使用,相辅相成.当触电伤员如意识丧失,应在10秒钟内用看、听、试的方法,判定伤员呼吸、心跳情况.一看伤员的胸部、腹部有无起伏动作;二是用耳贴近伤员的口鼻处,听有无呼气的声音;三是试测口鼻有无呼气的气流,再用两手指轻试左或右侧喉结旁凹陷处的颈动脉有无搏动.通过看、听、试,发现既无呼吸又无颈动脉搏动,可判定呼吸心跳停止,应立即按心肺复苏支持生命的三项基本措施,且要始终保持伤员气道畅通,用口对口(鼻)人工呼吸法、胸外心脏挤压法现场就地抢救.1 口对口(鼻)人工呼吸法人工呼吸的方法很多,主要是采用人工机械方法,使肿部膨胀和收缩来达到氧气和废气交换的目的.口对口(鼻)人工呼吸法?
Human life so to survive, mainly by physiological oxygenation .Oxygenation is simply the heartbeat caused by blood circulation and lung breathing caused by oxygen and exhaust exchange process.Any kind of “suspended animation ”Phenomenon is to interrupt the process .We can use artificial methods to temporarily replace the physiological oxygenation has been suspended, in order to transition to the normal function of recovery, which is called artificial cardiopulmonary resuscitation first aid .Artificial cardiopulmonary Resuscitation emergency method is to complete the process of artificial oxygenation, is divided into two aspects: First, the mouth of the mouth (nose) artificial respiration, the expansion and contraction of the lungs, inhaled oxygen for the blood; the second is the chest compression , So that the heart to play a “pump” role, the oxygen-containing blood to the brain and body .Two methods combined use, complement each other .When the electric shock casualties such as loss of consciousness, should be used within 10 seconds to see, listen, test method, Determine the wounded breathing, heartbeat situation.A look at the wounded chest, abdomen with or without ups and downs; Second, with the ear close to the wounded nose and mouth, listen to the sound of exhalation; Third, test whether the breath of the nose and mouth airflow , Then two fingers light Right or left thoracic depression at the carotid artery with or without beating.Through the look, listen, test, found no breathing and no carotid artery pulsation can be determined to stop breathing heartbeat, cardiopulmonary resuscitation should be immediately supported by the three basic measures of life , And should always keep the injured airway unobstructed, mouth to mouth (nose) artificial respiration, chest cardiac extrusion method on-site rescue .1 mouth counterparts (nose) artificial respiration artificial respiration many ways, mainly using artificial Mechanical methods to swollen swollen and contracted to achieve the purpose of oxygen and exhaust exchange. Mouth counter (nose) artificial respiration?
