The normal mean pulmonary artery pressure is typically accepted to be within the range of 12-16 mmHg. This pressure reflects the average pressure in the pulmonary artery during the cardiac cycle, particularly during diastole when the heart is relaxed.

Maintaining this pressure is crucial, as significantly elevated pulmonary artery pressure can lead to conditions such as pulmonary hypertension, which can strain the right side of the heart and lead to complications. The measurement is usually taken during right heart catheterization, providing a direct assessment of pulmonary artery pressures in a clinical setting.

The ranges listed in the other options fall outside of this normal physiological range, and while they may represent conditions of high pressure or hypotensive states, they do not reflect the typical mean pulmonary artery pressure seen in healthy individuals. Understanding this normal range is important for healthcare professionals when assessing and managing patients with cardiac or respiratory diseases.
