ScvO2 Central Venous Oxygen Saturation

Assess adequacy of oxygen delivery relative to consumption using central venous oxygen saturation (ScvO2). Normal ScvO2 ≥70%; <70% indicates increased oxygen extraction and potential tissue hypoperfusion.

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

Assess adequacy of oxygen delivery relative to consumption using central venous oxygen saturation (ScvO2). Normal ScvO2 ≥70%; <70% indicates increased oxygen extraction and potential tissue hypoperfusion

Each component has a specific meaning:

  • Central venous oxygen saturation — The central venous oxygen saturation recorded for the scenario being assessed.

Note: Interpret the scvo2 result against the thresholds and context described above.

How to Use

Enter the central venous oxygen saturation for the scenario you are assessing. Assess adequacy of oxygen delivery relative to consumption using central venous oxygen saturation (ScvO2). Normal ScvO2 ≥70%; <70% indicates increased oxygen extraction and potential tissue hypoperfusion. Use the scvo2 result to inform your calculation.
