What is the normal pressure in the Right Atrium (RA)?

Explanation:
Right atrial pressure is a low filling pressure that mirrors the venous return entering the heart and the preload to the right ventricle. In healthy individuals, this pressure is only a few millimeters of mercury. The normal range is generally considered about 0 to 8 mmHg, with the mean around 2 to 6 mmHg. Therefore, the range 0–8 mmHg best reflects normal RA pressure. Pressures in the higher ranges indicate elevated central venous pressure or right-sided pathology—conditions like volume overload, right ventricular dysfunction, significant tricuspid disease, or advanced pulmonary hypertension can push RA pressure above normal.
