Types of Shock

Types of Shock

1. insufficient oxygenation/nutrient delivery to meet cell needs (perfusion and/or oxygenation)

2. Hypovolemic

   • Reduction in whole blood and/or plasma volume
     • Trauma
       • Hemorrhage
       • Rupture
     • Burns
       • Plasma loss
     • Dehydration
       • Vomiting
       • Polyuria
       • DIaphoresis

3. Cardiogenic

   • Pump failure (▼ contractility = ▼ CO)
     • Contusion
     • Tamponade
     • Myocarditis
     • Dysrythmias
     • Valve disease
     • Cardiomyopathy

4. Distributive

   • Septic
     • Infection ► cell destruction ► microvascular occlusion ► vasodilation
   • Limited oxygenation d/t vasodilation
     • Anaphylactic
       • Antibody response ► histamine release ► ▲ capillary permeability ► vasodilation, angioedema, bronchoconstriction
     • Neurogenic
       • Injury >T6 ► loss of sympathetic tone ► massive vavsodilation = unposed vagal response/hypotension and bradycardia
