Oxygen Delivery (DO2) Calculator

Calculate systemic oxygen delivery (DO2 = CO × CaO2 × 10) from cardiac output and arterial oxygen content to assess adequacy of oxygen transport to tissues.

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 = CO × CaO2 × 10) from cardiac output and arterial oxygen content to assess adequacy of oxygen transport to tissues

Each component has a specific meaning:

  • Cardiac output — The cardiac output recorded for the scenario being assessed.
  • Arterial oxygen content — The arterial oxygen content recorded for the scenario being assessed.

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

How to Use

Enter the cardiac output, arterial oxygen content for the scenario you are assessing. Calculate systemic oxygen delivery (DO2 = CO × CaO2 × 10) from cardiac output and arterial oxygen content to assess adequacy of oxygen transport to tissues. Use the do2 result to inform your calculation.
