🫁 Oxygen Consumption (VO₂ / VO₂I)
UseWhen to use: ICU metabolic demand estimate with CO/CI and a−v O₂ contents.

StrataRising VO₂ with falling SvO₂ suggests higher extraction demand.
LimitsWhen not to use: no mixed-venous sample. · Pitfall: ScvO₂ as SvO₂ without caveat. · Anesthesia lowers VO₂.

Fick VO₂.
When to use
When to use: ICU metabolic demand estimate with CO/CI and a−v O₂ contents.
How it works
VO₂ = CO × (CaO₂ − CvO₂) × 10; VO₂I uses CI.
