Hypovolemic shock

SHOCK

• Definition – Shock is characterised by systemic hypo tension due to either reduced cardiac output or  reduced effective circulating blood volume

• This leads to impaired tissue perfusion and cellular hypoxia

Types of shock depending on etiology

• Cardiogenic shock

• Hypovolemic shock

• Septic shock

• Neurogenic shock

• Anaphylactic shock

•  

Hypovolemic shock

• Mechanism – loss of blood or plasma volume leads to decreased cardiac output and reduced tissue perfusion

• Causes –

  • Massive hemorrhage

  • Fluid loss from severe burns

  • Vomitings

  • Severe dehydration
