1．Etiology 失血 Hemorrhagic shock 严重创伤 Traumatic shock 感染 Infective shock 过敏 Anaphylactic shock 大面积烧伤 Burn shock 急性心力衰竭 Cardiogenic shock 强烈的神经刺激 Neurogenic shock Etiology and Classification
2. Classification (1)病因分类( Classification of etiology (2)休克的始动环节分类 (Classification by initial changes of shock) A Hypovolemic shock A Vasogenic shock , Cardiogenic shock
（2）休克的始动环节分类 （Classification by initial changes of shock） Hypovolemic shock Vasogenic shock Cardiogenic shock 2．Classification （1）病因分类（Classification of etiology）
Hypovolemic Shock (Hemorrhage, Dehydration, Trauma, Plasma Loss) Decreased Circulating Blood Volume Inadequate Tissue Perfusion
Acidosis. Infection Neurogenic shock Anaphylactic Shock Increased vascular capacity Increased Capillary permeability Reduced Circulating Blood Volume Inadequate Tissue Perfusion
Acidosis, Infection
Cardiogenic shock Myocardial factor Non-myocardial factor Decreased Cardiac Output Inadequate Tissue Perfusion (共同的发病环是有效循环血量减少)
(共同的发病环节是有效循环血量减少） Myocardial factor Non-myocardial factor
