SVR — Systemic Vascular Resistance Calculator

Calculate Systemic Vascular Resistance (SVR) using the formula SVR = 80 × (MAP − CVP) / CO to assess afterload and guide vasopressor and vasodilator therapy in hemodynamically unstable 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 Vascular Resistance (SVR) using the formula SVR = 80 × (MAP − CVP) / CO to assess afterload and guide vasopressor and vasodilator therapy in hemodynamically unstable patients

Each component has a specific meaning:

  • Formula SVR = 80 × / CO — The formula svr = 80 × / co recorded for the scenario being assessed.

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

How to Use

Enter the formula SVR = 80 × / CO for the scenario you are assessing. Calculate Systemic Vascular Resistance (SVR) using the formula SVR = 80 × (MAP − CVP) / CO to assess afterload and guide vasopressor and vasodilator therapy in hemodynamically unstable patients. Use the svr calculator result to inform your calculation.
