4v²+RAP.

When to use

When to use: bedside echo screening for elevated pulmonary pressures.

How it works

RVSP ≈ 4×(TR Vmax)² + RAP.

Key points

  • 4v²+RAP.
  • Echo screening.
  • Next: echo PH workup.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

FAQ

Frequently asked questions

Does RVSP / PASP (TR Bernoulli) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is RVSP / PASP (TR Bernoulli) calculated in practice? Can you show a worked example?
Inputs: TR Vmax 3.2 m/s, Estimated RAP 10 mmHg, RAP shortcut (optional) IVC normal collapse → ≈3 mmHg → Result: Estimated RVSP 44 mmHg（4v² gradient: 41 mmHg, RAP used: 3 mmHg, Cue: ≈35–50 — intermediate elevation band） Inputs: TR Vmax 3.2 m/s, Estimated RAP 10 mmHg, RAP shortcut (optional) Use RAP number above → Result: Estimated RVSP 51 mmHg（4v² gradient: 41 mmHg, RAP used: 10 mmHg, Cue: >≈50 mmHg — higher PASP/RVSP teaching band; correlate clinically）
