Types of Shock

insufficient oxygenation/nutrient delivery to meet cell needs (perfusion and/or oxygenation)
Hypovolemic
1. Reduction in whole blood and/or plasma volume
  1. Trauma
    1. Hemorrhage
    2. Rupture
  2. Burns
    1. Plasma loss
  3. Dehydration
    1. Vomiting
    2. Polyuria
    3. DIaphoresis
Cardiogenic
1. Pump failure (▼ contractility = ▼ CO)
  1. Contusion
  2. Tamponade
  3. Myocarditis
  4. Dysrythmias
  5. Valve disease
  6. Cardiomyopathy
Distributive
1. Septic
  1. Infection ► cell destruction ► microvascular occlusion ► vasodilation
2. Limited oxygenation d/t vasodilation
  1. Anaphylactic
    1. Antibody response ► histamine release ► ▲ capillary permeability ► vasodilation, angioedema, bronchoconstriction
  2. Neurogenic
    1. Injury >T6 ► loss of sympathetic tone ► massive vavsodilation = unposed vagal response/hypotension and bradycardia
