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)

2010 (New)

2005 (Old):

• 不规律的宽 QRS 心动过速

d not be used• (may cause dege

neration of the rhythm to VF)

心动过缓 Bradycardia

• 症状性不稳定心动过缓

nfusions (an alternative to p

acing)

atropine while awaiting a pacer or if pacing was ineffective.

chronotropic drug infusions
