mean pulmonary arterial pressure

Mean pulmonary arterial pressure (mPAP) is the average pressure in the pulmonary arteries, the vessels carrying blood from the heart to the lungs. It reflects how hard the right side of the heart has to work to pump blood through the lungs. Normally, mPAP is between 8 and 20 mm Hg. Elevated mPAP suggests increased resistance in the pulmonary vessels, which can indicate conditions like pulmonary hypertension. Measuring mPAP helps doctors assess lung and heart health, guide treatment, and monitor the progression of pulmonary vascular diseases.
