人工呼吸 Provide Rescue Breathing 先进行两次人工呼吸,每次人工呼吸时间超过1秒 。 潮气量500-600ml，有胸廓起伏,避免迅速而强力的人工呼吸。 有人工气道二人进行CPR，则没分钟通气8至10次,人工呼吸时,胸外按压不应停止。 没有人工气道,救助者复苏的每周期为30次按压和2次呼吸,在按压暂停进行人工呼吸,每次呼吸超过1秒。 Give 2 rescue breaths, each over 1 seco- nd. with tidal volume of 500 to600 mL to produce visible chest rise, avoid rapid or forceful breaths. When an advanced airway is in place during 2-person CPR, ventilate at a rate of 8 to 10 bpm, no pause in chest compressions for delivery of ventilations. without an advanced airway in place, the rescuer(s) should deliver cycles of 30 compressions and 2 breaths. The rescuer delivers the breaths during pauses in compressions and delivers each breath over 1 second.

胸外心脏按压(external chest compression) ECC 心泵机制(cardiac pump) 胸泵机制(thoracic pump) Pump the blood to the organs 按压部位(position of compression) 胸骨下半部,双乳头之间 The lower half of the sternum between nipples

胸外心脏按压(external chest compression) ECC techniques Place the heel of one hand on the lower half of the sternm and the other hand on top of the first ,so that the hands are parallel. Be sure the long axis of the heel of your hand is placed on the long axis of the sternm your hand may be either extended or interlaced but should be kept off the chest. 一只手的掌跟在胸骨下半部，另一只手放于其上，双手平行。掌跟的长轴放在胸骨的长轴上。手指伸展或交锁，但应离开胸部。

胸外心脏按压(external chest compression) ECC techniques Lock the elbows in position, with the arms straightened. Position your shoulders directly over your hands so that the thrust for each chest compression is straight down on the sternum. Release the pressure completely and allow the chest to return to its normal position after each compression. Keep your hands in contact with the victim’s sternum to maintain proper hand position. 双肘关节固定，双臂垂直。 双肩在双手正上方以使每次胸部挤压的冲击直接使胸骨下压。 每次挤压后必须完全解除压力，使胸部回到正常位置。 使手与胸骨接触以保持正确手的位置。

胸外心脏按压(external chest compression) ECC techniques 按压频率100次/分钟 按压幅度4-5cm 按压-通气比值30:2 按压与放松时间1:1 每2分钟更换按压者 尽量不间断,间断不超过10秒 Compression rate 100/min Depress the sternum 4 to 5cm Compression-ventilation ratio 30:2 Compression /relaxation time 1:1 Switch the compressor every 2 min. Minimize interruption of chest compression, limit interruption to no more than 10 seconds.

除颤(fibrillation treatment) defibrillation SCA 最常见和最初发生的心律 失常是心室纤颤（VF）。 电除颤是终止 VF 最有效的方 法。 随着时间的推移，成功除颤的 机会迅速下降。 短时间 VF 既可恶化并导致心 脏停搏。 the most frequent initial rhythm in witnessed SCA is ventricular fibrillation (VF) the treatment for VF is electrical defibrillation, the probability of successful defibrillation diminishes rapidly over time, VF tends to deteriorate to asystole within a few minutes.

BLS法则(algorithm) BLS algorithm

小结：CPR操作流程 ①判断意识：拍打肩部并呼叫病人 ②求救呼叫：急呼120，或者通知身旁其他人呼叫救护人员 ③开放气道：仰头抬颏法，左手小鱼际按压额部，右手食指中指抬举颏部，使头颈后仰 ④去除异物：用单手食指钩出口腔中固体异物（未见异物，可省去此操作） ⑤检查呼吸：面感鼻孔气流、耳听呼吸声音、眼观胸廓起伏（专业人员需同时检查脉搏，时间小于10秒） ⑥人工通气：吸一口气，一手食指拇指捏住鼻孔，口对口密闭，两次缓慢人工通气（每次吹气时间不少于1秒，两次吹气间留有呼气时间，吹气同时要观察到胸廓起伏） ⑦胸外按压：部位取胸骨中下三分之一处，也可简便取两乳头连线中点（右手沿一侧肋弓向上摸到剑突，左手掌根紧贴剑突上两横指处，两手掌根重叠，手指翘起不得按于肋骨上）；频率100次/分，按下与松开的时间相同（松开时手掌不得离开胸壁）；两手臂肘关节伸直，垂直用力，幅度4到5厘米；按压通气比为30比2 ⑧再次检查：完成5个循环的按压通气后评估心跳呼吸（面感鼻孔气流、耳听呼吸声音、眼观胸廓起伏，同时手指触摸颈动脉搏动） ⑨即刻除颤：涂抹电极膏，取360J功率，充电后招呼周围人远离病人身体，非同步电击一次（部位：胸骨右缘第二肋间、左腋前线第五肋间） ⑩继续抢救：继续5个循环的按压通气，然后再次检查心跳呼吸（若心跳呼吸无恢复可重复“除颤－按压通气－检查”步骤；若心跳呼吸已恢复，摆放复苏体位）

Sequence of CPR Step 1 Step 2 Step 3 Step 4

One rescuer CPR Compression rate 100/min Depress the sternum 4 to 5cm Compression-ventilation ratio 30:2 Compression /relaxation time 1:1 Switch the compressor every 2 min. Minimize interruption of chest compression, limit interruption to no more than 10 seconds.

Two rescuer CPR Give 2 rescue breaths, each over 1 seco- nd. with tidal volume of 500 to600 mL to produce visible chest rise, avoid rapid or forceful breaths. When an advanced airway is in place during 2-person CPR, ventilate at a rate of 8 to 10 bpm, no pause in chest compressions for delivery of ventilations. without an advanced airway in place, the rescuer(s) should deliver cycles of 30 compressions and 2 breaths. The rescuer delivers the breaths during pauses in compressions and delivers each breath over 1 second.
