Right Ventricular Systolic Pressure Calculator

The Right Ventricular Systolic Pressure Calculator estimates RVSP in mmHg using tricuspid regurgitation velocity and IVC measurements. This tool helps healthcare professionals assess pulmonary pressure and right heart function quickly. Whether you are screening for hypertension, monitoring a chronic condition, or reviewing echocardiogram data, this calculator offers accurate estimates to support clinical decisions.

Enter the TR velocity in m/s (range: 0.5-5.0 m/s)
Enter the IVC diameter in cm (range: 1.0-3.5 cm)
Enter the IVC collapsibility percentage (range: 0-100%)

How Right Ventricular Systolic Pressure Is Calculated

Right Ventricular Systolic Pressure measures the force the heart uses to pump blood to the lungs. We use the Modified Bernoulli Equation to find this number accurately.

RVSP = 4 × (TR Velocity)² + RAP

Where:

  • TR Velocity = Speed of blood flow through the tricuspid valve (m/s)
  • RAP = Right Atrial Pressure estimated from IVC size and collapsibility

First, the tool calculates the pressure gradient based on the speed of the tricuspid regurgitation jet. Then, it estimates the Right Atrial Pressure (RAP) by checking the IVC diameter and how much it collapses when you breathe. Finally, it adds the gradient and the RAP together. This provides the total pressure inside the right ventricle, which helps doctors understand heart function without surgery.

What Your Right Ventricular Systolic Pressure Means

Your RVSP result tells you the pressure level in the right side of the heart during a heartbeat. This number helps identify if the heart is working harder than normal to push blood to the lungs.

Normal Heart Function (<30 mmHg)

If the result is below 30 mmHg, the right ventricle pressure is normal. This suggests the pulmonary arteries are clear and the heart is pumping efficiently.

Borderline Risk (36-45 mmHg)

A result in this range is slightly elevated. You should re-evaluate the patient or check for early signs of lung disease or volume overload.

High Pressure (>60 mmHg)

Scores above 60 mmHg indicate a high likelihood of pulmonary hypertension. Immediate clinical review and further testing are usually required.

Important: High pressure on the right side can strain the heart over time and lead to heart failure if left untreated.
