What is the normal pulmonary artery pressure range in right heart catheterization?

• A. 0-10 mmHg
• B. 10-20 mmHg
• C. 20-30 mmHg
• D. 30-40 mmHg

Answer: (B)

The normal range for pulmonary artery pressure, as measured during right heart catheterization, is typically in the range of 10-20 mmHg. This range reflects normal hemodynamics within the pulmonary circulation. Maintaining this pressure range is essential for efficient gas exchange and the overall functioning of the cardiovascular system. In pulmonary hypertension, for instance, pressures can exceed this normal range, indicating an underlying pathological state that may warrant further investigation and intervention. Understanding the significance of pulmonary artery pressures is crucial, as deviations from the normal range can have profound implications for both maternal and fetal health in the context of pregnancy.
