Which of the following values would indicate normal right atrial pressure?

A right atrial pressure measurement is a critical parameter in assessing the hemodynamic status of a patient. Normal right atrial pressure typically ranges from 2 to 6 mmHg. This value indicates that the right atrium is functioning well in terms of venous return and pressure management. Maintaining this pressure is important for ensuring adequate blood flow into the pulmonary circulation via the right ventricle.

Values greater than 6 mmHg may suggest conditions such as right-sided heart failure, fluid overload, or other circulatory issues that could lead to increased pressures in the right atrium. On the other hand, values significantly lower than 2 mmHg could reflect hypovolemia or inadequate venous return. Therefore, understanding and monitoring the normal reference range is essential for effective assessment and management of a patient's cardiovascular status.
