Open Airway
Why open airway is important?
• It is essential to provide adequate respiration for victims (functional respiration)
Normal airway vs Obstructed airway
How to Open Airway?
Tilt the head back- head tilt (don’t do this if cervical spine injury is suspected)
ECG Patterns of Cardiac Arrest
无脉性室速 Pulseless VT
室颤 VTF
无脉性电活动 Pulseless Electrical
Activity 心室停搏 Asystole
Cardio-Pulmonary Resusitation
An emergency procedure in which the heart and lungs are made to work by manually compressing the chest overlying the heart and forcing air into the lungs. CPR is used to maintain circulation when the heart stops pumping, usually because of disease, drugs, or trauma.
10-12/min with pulse 8-10/min without pulse Vt=400-500ml in an adult (amount to produce
visible chest lifting) A deliberate pause is incorporated after every

Chest Compression
Mechanisms of Cardiac Compression
Cardiac pump Thoracic pump
Chest Compression Skills
• Observe colour of skin on face
• Check if carotid pulse present or brachial for children.
Take no more than 10s to do this
Effective CPR is based on the artificial delivery of oxygenated blood to systemic circulatory beds at rates that are sufficient to preserve vital organ function and at the same time providing the physiologic substrate for the rapid return of spontaneous circulation

Response (consciousness) Airway Control Ventilation (Breathing) Chest Compression
Initial steps of CPR
An emergency procedure consisting of external cardiac massage and artificial respiration; the first treatment for a person who has collapsed and has no pulse and has stopped breathing; attempts to restore circulation of the blood and prevent death or brain damage due to lack of oxygen
Lift the jaw-chin lift Jaw thrust (First Choice if cervical spine
injury is suspected) Clear the airway (very important for infant)
Open Airway
Head Tilt-Chin Lift
• CA may be caused by airway blockage
• Unconscious patients tend to have airway obstructed by posterior displacement of the tongue or epiglottis due to the decrease of muscle tone decreased tone of the genioglossus muscle (颏舌肌） in particular
-Clinical Death
Medical emergency with absent or inadequate contraction of the left ventricle of the heart that immediately causes bodywide circulatory failure. The signs and symptoms include loss of consciousness; rapid shallow breathing progressing to apnea (absence of breathing); profoundly low blood pressure (hypotension) with no pulses that can be felt over major arteries; and no heart sounds.

Basic Life Support (RABC)
Cardiac arrest is one of the greatest of all medical emergencies. Within several minutes, there is lack of oxygen (tissue hypoxia), leading to multiple organ injury. Unless cardiac arrest is quickly corrected, it is fatal.
