PVR — Pulmonary Vascular Resistance Calculator

Calculate Pulmonary Vascular Resistance (PVR) using PVR = 80 × (mPAP − PCWP) / CO to assess right ventricular afterload and guide therapy in pulmonary hypertension and right heart failure.

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 Pulmonary Vascular Resistance (PVR) using PVR = 80 × (mPAP − PCWP) / CO to assess right ventricular afterload and guide therapy in pulmonary hypertension and right heart failure

Each component has a specific meaning:

  • PVR = 80 × / CO — The pvr = 80 × / co recorded for the scenario being assessed.

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

How to Use

Enter the PVR = 80 × / CO for the scenario you are assessing. Calculate Pulmonary Vascular Resistance (PVR) using PVR = 80 × (mPAP − PCWP) / CO to assess right ventricular afterload and guide therapy in pulmonary hypertension and right heart failure. Use the pvr calculator result to inform your calculation.
