Cardiovascular system mnemonic

Determinants of cardiac output and blood pressure

The mnemonic

CO = SV x HR; BP = CO x TPR

What each word stands for

  • COCardiac output
  • SVStroke volume
  • HRHeart rate
  • BPBlood pressure
  • TPRTotal peripheral resistance

Why it matters clinically

Predicts haemodynamic response to drugs, bleeding or sepsis.

Where it stops being reliable

It does not break SV into preload, contractility and afterload.
