Pulmonary Hypertension

PAP

07/23/2010

Question:

Can pulmonary hypertension be measured by an echocardiogram? What is the difference between PAP and systolic PAP? It measured me as 35-40mmHg using the echocardiogram, what is this?

Answer:

PAP is pulmonary artery pressure. It refers to the pressure in the pulmonary artery (the vessels that take blood through the lungs).

Like with the blood pressure measurement on your arm (systemic blood pressure) there is the top number (systolic) and the bottom number (diastolic).
 
The normal pressures in the lungs are about 25/8. 25 is the systolic PAP.  These pressures can only be measured by floating a catheter in the vessels (right heart cathetertization).  sPAP (systolic PAP) can be estimated by echocardiogram.
