Shock States — Classification, Profiles and Management

What shock is

A severe mismatch between the supply and demand of oxygen is the common feature of all types of shock.^[1] Circulatory shock is a life-threatening syndrome that results in multiorgan failure and a high mortality rate.^[2] In anaesthetised adults, oxygen consumption fell in proportion to oxygen delivery once delivery dropped below a critical value of 330 mL/min/m² (8.2 mL/min/kg); above it, consumption plateaued.^[5]

Sepsis-3 defines septic shock as a subset of sepsis in which particularly profound circulatory, cellular and metabolic abnormalities carry a greater risk of mortality than sepsis alone; it is identified clinically by a vasopressor requirement to maintain a MAP of 65 mmHg or greater and a serum lactate above 2 mmol/L in the absence of hypovolaemia.^[3]
