WebJan 31, 2024 · tricuspid valve velocity (4v2 = TV pressure gradient) estimated CVP (=RA pressure) Bernoulli equation; PASP = RVSP (in the absence of RVOTO or pulmonic stenosis) RVSP = 4v2 + CVP; Mean PAP can be approximated because PAPm = 0.61•sPAP + 2. A systolic PAP of 30 mm Hg typically implies a mean PAP more than 20 mm Hg, i.e. … WebPeak velocity is a specific point in the movement at which velocity of the measured object (center of mass, barbell, projectile) is at its highest. Depending on the type of movement being performed, peak velocity will occur at different regions within the movement. Read More: Does mercury cause high blood pressure?
