health.oxygen-consumption-fick Calculator
Calculates oxygen consumption (VO₂) using the Fick principle from cardiac output and arterio-venous oxygen difference. VO₂ is the gold standard measure of metabolic rate during exercise — the Fick calculation is used in cardiac catheterisation labs to determine exercise cardiac output.
Inputs
Cardiac Output L Min
Reference formula or conversion factor shown for context.
Arterial O2 Content Ml Dl
Reference formula or conversion factor shown for context.
Venous O2 Content Ml Dl
Reference formula or conversion factor shown for context.
Results
VO₂ oxygen consumption (mL/min)
The arithmetic total of all input values.
O₂ extraction ratio
The proportional relationship between two quantities.
normal resting VO₂
Sample size or count used in the calculation.
Fick: VO₂ = CO × (CaO₂-CvO₂)
Reference formula or conversion factor shown for context.
O₂ delivery DO₂ (mL/min)
Sample size or count used in the calculation.
critical DO₂
Reference formula or conversion factor shown for context.
