RV Systolic Pressure / PASP (TR jet)
RV systolic pressure / PASP from the tricuspid-regurgitation jet velocity (4v^2 + RAP, simplified Bernoulli) (Yock 1984).

Example
- Peak TR jet velocity
- 2.8 m/s
- Estimated right-atrial pressure
- Intermediate (8 mmHg)
Result: RVSP / PASP 39.4 mmHg — elevated.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Framing
- A resting PASP above ≈ 35 mmHg is commonly flagged for further pulmonary-hypertension evaluation.
What you enter
- Peak TR jet velocity
- Estimated right-atrial pressure (from IVC)
How this is calculated
- Formula
- RVSP = 4·(TR Vmax)² + RAP; equals PASP absent pulmonic stenosis / RVOT obstruction. RAP from IVC: 3 / 8 / 15 mmHg.
