How to calculate oxygen consumption
This calculator finds oxygen consumption using the Fick principle, from cardiac output and the arteriovenous oxygen difference.
How the calculation works
Oxygen consumption = Cardiac output × A-V oxygen difference × 10, converting units to mL/min.
Example
Cardiac output of 5 L/min with an A-V oxygen difference of 5 mL/dL: 5×5×10 = 250 mL/min.
Frequently asked questions
How is Result calculated?
Result = [Cardiac output] × [A-V oxygen difference] × 10.

Pro Tips for Oxygen Consumption
- This is the Fick principle, a foundational relationship in cardiovascular and respiratory physiology connecting blood flow to oxygen consumption.
- Normal resting oxygen consumption for an adult is commonly cited around 250 mL/min, though this scales up significantly with exercise.
Common Oxygen Consumption Mistakes to Avoid
- Omitting the unit conversion factor (×10), which is needed to reconcile the L/min and mL/dL units into a standard mL/min result.
