What is the normal pressure in the Right Ventricle (RV)?

• A. 10-20 mmHg
• B. 20-30 mmHg
• C. 30-40 mmHg
• D. 40-50 mmHg

Answer: (B)

The right ventricle is built to generate only modest pressures because it pumps into the low-resistance pulmonary circulation. In a normal adult, the systolic pressure of the right ventricle is typically in the range of about 20 to 30 mmHg. Values much lower than this would be unusually low for systole, while higher values indicate increased afterload from the pulmonary circulation (as seen in pulmonary hypertension or RV outflow obstruction). So the 20–30 mmHg range best reflects normal RV systolic pressure, aligning with how the RV operates under normal conditions.
