Types of Shock

• Any heart problem is a circulatory problem
• Shock a condition of profound hemodynamic and metabolic disturbance due to inadequate blood flow and inadequate oxygen delivery to the capillaries and tissues of the body
• Types of Shock

  Hypovolemic Shock - This results from loss of circulating volume
• Types of Shock

  Cardiogenic Shock - This results from decreased cardiac output
• Types of Shock

  Distributive or Vasogenic Shock - This results from massive vasodilatation
• Distributive Shock

  Neurogenic or Spinal Shock - This results from generalized vasodilatation due to conditions affecting the medulla oblongata and SNS
• Distributive Shock

  Septic Shock or Toxic Shock - This results from severe infection, commonly caused by a gram-positive organism; endotoxins released by microorganisms cause massive vasodilatation
• Distributive Shock

  Anaphylactic Shock - This results from severe allergic reaction; mediated by release of histamine, bradykinin, leukotrienes and prostaglandins
• Types of Shock

  Hypovolemic Shock - e.g., hemorrhage, dehydration (nausea and vomiting, diarrhea, polyuria), burns, trauma and ascites
• Types of Shock

  Cardiogenic Shock - e.g., MI, dysrhythmias, CHF, cardiac tamponade
• Types of Shock

  Neurogenic or Spinal Shock - e.g., spinal cord injury, head injury, general anesthesia, overdose of opiates, barbiturates, and tranquilizers.
• All types of shock are hypo-tachy-tachy except NEUROGENIC shock which is hypo-brady-tachy.
• All types of shock have septic shock component due to lysis of colonic bacteria and due to destruction of Kupffer cells
• Shock a condition of profound hemodynamic and metabolic disturbance due to inadequate blood flow and inadequate oxygen delivery to the capillaries and tissues of the body
• All types of shock are hypo-tachy-tachy except NEUROGENIC shock which is hypo-brady-tachy
