What is the normal pressure in the Pulmonary Artery (PA)?

Explanation:
Pulmonary artery pressure is much lower than systemic pressure, and it has distinct values for systole, diastole, and the mean. A normal systolic pulmonary arterial pressure is typically about 20–30 mmHg, while diastolic is roughly 4–12 mmHg and mean around 9–15 mmHg. In many exam contexts, the term “normal PA pressure” is taken to refer to the systolic value, which sits in the 20–30 mmHg range. The other options are outside the typical systolic normal range (either too low or too high), so the 20–30 mmHg range best represents a normal PA pressure.
