DO2 — Oxygen Delivery Calculator

Calculate systemic oxygen delivery (DO2) using the formula DO2 = CO × CaO2 × 10 to assess the amount of oxygen transported to tissues per minute 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 delivery (DO2) using the formula DO2 = CO × CaO2 × 10 to assess the amount of oxygen transported to tissues per minute in critically ill patients

Each component has a specific meaning:

  • Formula DO2 = CO × CaO2 × 10 — The formula do2 = co × cao2 × 10 recorded for the scenario being assessed.

Note: Interpret the do2 calculator result against the thresholds and context described above.

How to Use

Enter the formula DO2 = CO × CaO2 × 10 for the scenario you are assessing. Calculate systemic oxygen delivery (DO2) using the formula DO2 = CO × CaO2 × 10 to assess the amount of oxygen transported to tissues per minute in critically ill patients. Use the do2 calculator result to inform your calculation.
