What is considered normal right atrial pressure (RAP)?

• A. 0-4 mmHg
• B. 2-6 mmHg
• C. 6-10 mmHg
• D. 10-15 mmHg

Answer: (B)

Normal right atrial pressure (RAP) ranges from 2 to 6 mmHg. This pressure reflects the volume of blood returning to the right side of the heart and the ability of the heart to pump that blood into the lungs. In a healthy individual, maintaining RAP within this range is crucial, as it indicates that the right atrium can effectively manage venous return and maintain adequate circulation. Values below this range can signify low blood volume or dehydration, while higher readings may suggest conditions such as heart failure, fluid overload, or right-sided heart dysfunction. Thus, understanding the normal range of RAP is essential for assessing cardiac function and diagnosing potential cardiovascular issues.
