Right Ventricular Systolic Pressure

Pssst! It's me, the website.

I just wanted to let you know that even though I'm looking quite old, I'm still a millenial.
So I just had a "New Year, New Me" moment and my resolution is to become a new and improved version of myself in a couple of weeks.
Don't worry, my wisdom won't change. You're still going to find the same useful information here. Stay tuned!

CVP:	mmHg
Vmax of TR Jet	m/sec

RVSP	mmHg

How to calculate a RVSP.

Obtain a CWD of the long axis view of the tricuspid valve. Tricuspid regurgitation must be present to make this calculation. Tricuspid regurgitation is present in most normal individuals so this calculation should be able to be made in almost everyone. A CWD of the TR jet will yield a peak velocity. Four times the square of the peak velocity of the TR jet yields the peak pressure during right ventricular systole. The RVSP will equal the PASP if pulmonary stenosis or a RVOT outlet obstruction is absent.
