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.
