Pulmonary Artery Systolic Pressure

Pulmonary Artery Systolic Pressure

How to calculate Pulmonary Artery Systolic Pressure.

  1. Obtain a CWD of the long axis view of the pulmonary valve. A pulmonary regurgitant jet is required to make this calculation. Once the flow profile of the CWD of the PR jet is obtained, the minimum velocity (Vmin) which occurs at end-diastole will represent the pulmonary artery valve gradient at the end of diastole. Adding this gradient to the CVP will yield the PAD pressure.
