Inputs

Patient values are shared with every calculator.
When to use
- Right heart catheterization or with a mixed venous saturation.
Pearls and pitfalls
- Assumed VO₂ can be off by 25% or more; measured VO₂ is better.
Why use
Bedside cardiac output when thermodilution is unavailable.
CO = VO₂ ÷ [(CaO₂ − CvO₂) × 10]; VO₂ assumed 125 mL/min/m² × BSA
