Cardiac arrest can be caused by
• 室颤 VF
• 室速 ( 无脉 )VT
• 无脉性电活动 PEA
• 心博停止 asystole. 无脉性心动过缓 Pulseless bradycardia
4 rhythms
• 室颤 无脉性室速• VF/Pulseless VT
• chest compressions (CC)• early Defibrillation (DF)
Early recognition cardiac arrest
•及早识别心跳骤停
外行急救lay rescuer 1. 突然晕倒 suddenly collapse 2. 意识消失 Unresponsive 3. 无呼吸或无正常呼吸 not breathing 4.Seizure (not normally,gasping).
• cardiac arrest• 降低脉搏检查的重要性• Minimize the importance of pulse checks
不检查脉搏 Not check for a pulse
• 2005 (Old): • “Look, listen, and feel”
•2010 (New): NO: “Look, Listen, Feel for Breathing”* 30 compressions 2 breaths
•NO: “Look, Listen, Feel for Breathing”* 不看 不听 不觉
A Change From A-B-C to C-A-B
•“Adults” •Children•infants (excluding thenewly born)

Chest Compressions*
• 2010 (New):
• Hands-Only™
• “push hard and fast”
• on the center of the chest
• 动手不动口• 30 compressions to 2 breaths
Chest Compression Rate: At Least 100 per Minute*
• 2010 (New): • chest compressions at a rate of• at least 100/min.( 快 ! 不间断 )• 2005 (Old): • Compress at a rate of about 100/min.
Chest Compression Depth*
• 2010 (New): hard !• The adult sternum should be depressed • at least 2 inches (5 cm).• 2005 (Old): • approximately 1,1/2 to 2 inches • (approximately 4 to 5 cm).

电击治疗 ELECTRICAL THERAPIES
• AED Use in Children Now Includes Infants
• 2010 (New):• <1 year of age.
• 2005 (Old):• Not use of AEDs for infants <1 year of age.
先除颤 VS 先 CPR ?
• CPR
• <3min• Defibrillation• However, in monitored patients, the time from
VF to shock delivery should be under 3 minutes
1 次除颤 vs 3 连续除颤 ?
• 2010 (No Change From 2005):
• 一次电击后
• 立即 CPR

电极放置 Electrode Placement
• 2010 (Modification of Previous Recommendation):
AED electrode pads positions :
lateral
posterior
Anterior left infra scapular
right infrascapular
胸骨旁 ( 锁骨下 )
2005 (Old):
• conventional sternal-apical (anteriorlateral) position.
• Right pad left pad • Sternal apical• 胸骨旁 ( 锁骨下 ) 心尖
• right or left upper back.
ADVANCED CARDIOVASCULAR LIFE SUPPORT
监测 PETCO2 :
1. 确定气管导管位置 confirming tracheal tube placement
2. 监测 CPR 有效性 monitoring CPR quality
3. 检查心跳恢复 detecting ROSC
CPR 质量
药物 New Medication Protocols• 2010 (New):
• 阿托品不常规• 用于 PEA/asystole• Atropine • not routine use • for PEA/asystole
2005 (Old):
阿托品用于高级心血管生命支持 Atropine included in the ACLS 心搏停止 asystole or slow PEA 可用阿托品Atropincould be considered..
心动过速 tachycardia
• 规律的 Regular• 单型 monomorphic• 宽 QRS 心动过速• wide-complex tachycardia
• 腺苷 Adenosine
• (rhythm is regular)

d not be used• (may cause dege
neration of the rhythm to VF)
心动过缓 Bradycardia

acing)
atropine while awaiting a pacer or if pacing was ineffective.
chronotropic drug infusions
