What is the normal mean pulmonary artery pressure range?

The normal mean pulmonary artery pressure range is typically accepted to be between 10 and 20 mmHg. This measure is critical as it provides insight into the pressures within the pulmonary circulation, which can be reflective of right heart function and can help identify potential pulmonary hypertension. Elevated pressures may indicate various pathologies, such as left heart disease, lung disease, or pulmonary vascular disorders. It is important to monitor this value, especially in critically ill patients, to guide treatment decisions and assess their hemodynamic status effectively. The choice that identifies the range as 10-20 mmHg captures this normal physiological state accurately.
