Portal Vein Pressure Gradient Calculator

Estimate portal venous pressure from HVPG measurements and clinical parameters. Normal portal pressure 5–10 mmHg; portal hypertension >10 mmHg; clinically significant >12 mmHg.

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

Estimate portal venous pressure from HVPG measurements and clinical parameters. Normal portal pressure 5–10 mmHg; portal hypertension >10 mmHg; clinically significant >12 mmHg

Each component has a specific meaning:

  • HVPG measurements — The hvpg measurements recorded for the scenario being assessed.
  • Clinical parameters — The clinical parameters recorded for the scenario being assessed.

Note: Interpret the portal vein pressure result against the thresholds and context described above.

How to Use

Enter the HVPG measurements, clinical parameters for the scenario you are assessing. Estimate portal venous pressure from HVPG measurements and clinical parameters. Normal portal pressure 5–10 mmHg; portal hypertension >10 mmHg; clinically significant >12 mmHg. Use the portal vein pressure result to inform your calculation.
