Oxygen Consumption (VO2) Calculator

Calculate systemic oxygen consumption (VO2 = CO × (CaO2 − CvO2) × 10) using the Fick principle to assess metabolic demand and oxygen utilization in critically ill patients.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate systemic oxygen consumption (VO2 = CO × (CaO2 − CvO2) × 10) using the Fick principle to assess metabolic demand and oxygen utilization in critically ill patients

Each component has a specific meaning:

  • Fick principle — The fick principle recorded for the scenario being assessed.

Note: Interpret the vo2 result against the thresholds and context described above.

How to Use

Enter the Fick principle for the scenario you are assessing. Calculate systemic oxygen consumption (VO2 = CO × (CaO2 − CvO2) × 10) using the Fick principle to assess metabolic demand and oxygen utilization in critically ill patients. Use the vo2 result to inform your calculation.
