Question

A 50-year-old woman on ICU has a PiCCO catheter. Her SVRI (systemic vascular resistance index) is 800 dyn·s·cm⁻⁵·m² (low, normal 1700-2400). CI is 5.5 L/min/m² (high). GEDI is 780 mL/m² (normal). ELWI is 9 mL/kg (mildly elevated). What haemodynamic pattern does this represent?

Accepted Answer

Hyperdynamic distributive (vasodilatory) shock - high CI with low SVRI is the hallmark of distributive shock (sepsis, anaphylaxis, neurogenic); the vasopressor strategy should focus on restoring SVR (noradrenaline) rather than augmenting cardiac output

Answer

Cardiogenic shock

Answer

Hypovolaemic shock

Answer

Obstructive shock

Answer

Normal haemodynamics
