What is considered normal mean pulmonary artery pressure?

Mean pulmonary artery pressure is an important hemodynamic parameter that reflects the pressure in the pulmonary artery, which is responsible for transporting blood from the right side of the heart to the lungs for oxygenation. Normal values for mean pulmonary artery pressure range from approximately 10 to 20 mmHg in healthy individuals.

This range is crucial for ensuring that the right ventricle can effectively pump blood into the pulmonary circulation without excessive resistance, which can lead to increased workload on the heart and potential heart failure. Maintaining pressures within this range allows for optimal gas exchange and overall cardiovascular health.

Understanding these values helps healthcare professionals monitor and assess patients who may be at risk for pulmonary hypertension or other cardiovascular issues. It also aids in recognizing when further diagnostic evaluation or intervention may be necessary.
