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 RVSP from tricuspid regurgitation velocity using modified Bernoulli equation plus estimated RAP

Each component has a specific meaning:

  • Tricuspid regurgitation velocity — The tricuspid regurgitation velocity recorded for the scenario being assessed.

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

How to Use

Enter the tricuspid regurgitation velocity for the scenario you are assessing. Estimate RVSP from tricuspid regurgitation velocity using modified Bernoulli equation plus estimated RAP. Use the rvsp estimate result to inform your calculation.
