health.oxygen-consumption-vo2 Calculator
Calculates oxygen delivery (DO₂) and consumption (VO₂) with extraction ratio from haemoglobin, saturation, and cardiac output. Critical oxygen extraction ratio above 50% indicates that oxygen delivery has fallen below the threshold where DO₂ becomes the limiting factor.
Inputs
Do2 Ml Min
Reference formula or conversion factor shown for context.
Cao2 Ml Dl
Reference formula or conversion factor shown for context.
Cvo2 Ml Dl
Reference formula or conversion factor shown for context.
Cardiac Output L Min
Reference formula or conversion factor shown for context.
Results
VO2 oxygen consumption (mL/min)
The arithmetic total of all input values.
oxygen extraction ratio ERO2
The proportional relationship between two quantities.
VO2 = CO × (CaO2-CvO2) × 10
