What is considered a normal pulmonary artery mean pressure?

The normal range for pulmonary artery mean pressure is 9-18 mmHg. This value reflects the average pressure within the pulmonary artery during the cardiac cycle and is an important parameter in assessing right heart function and pulmonary circulation. When measuring pulmonary artery pressures, values within this range indicate adequate function and are critical for ensuring proper blood flow from the right side of the heart to the lungs for oxygenation.

When pressures fall outside this range, it could be indicative of various clinical conditions, such as pulmonary hypertension or heart failure, necessitating further evaluation and management. This understanding is crucial in critical care settings, where monitoring hemodynamic values can guide treatment strategies and improve patient outcomes.
