Pulmonary pressure from TV and PV signals
TR-derived systolic PAP and PR-derived PAEDP.
Clinically reviewed 24 May 2026 · EchoRapp clinical content
Simple approach
Use TR peak velocity for systolic PAP and PR end-diastolic velocity for PAEDP. Add RA pressure where required by the calculation.
Detailed tutorial
The linked icon marks the derived pressure-gradient relationship. TR velocity derives TR gradient, then RA pressure contributes to systolic PAP. PR end-diastolic velocity derives the PR-ED gradient used for PAEDP.
