The pulmonary artery is the large blood vessel that carries blood from the heart's right ventricle to the lungs, where it picks up oxygen. An estimated pulmonary artery pressure of 35 to 40 mm Hg or greater on echocardiography suggests pulmonary hypertension. The Oxford Textbook of Advanced Critical Care Echocardiography provides a physiological and evidence-based reference guide to the principles and techniques of advanced echocardiography. Pulmonary hypertension is hard to diagnose early because it's not often detected in a routine physical exam. definitions Pulmonary hypertension is defined as a mean pulmonary arterial pressure (mPAP) greater than 20 mm Hg at rest as per the Sixth World Symposium on Pulmonary Hypertension in Pulmonary hypertension is a condition in which the blood pressure inside the pulmonary artery is too high. Pulmonary hypertension is a rare lung disorder in which the arteries that carry blood from the heart to the lungs become narrowed, making it difficult for blood to flow through the vessels. The most recent definition, as of May 2020, of pulmonary hypertension now defines >20 mmHg (rather than >25 mmHg) as pulmonary hypertension. Pulmonary arterial hypertension (PAH) is a specific subgroup of pulmonary hypertension (PH). To quantify pulmonary hypertension with echocardiography it is necessary to measure the maximal tricuspid regurgitation velocity with CW Doppler.
