Pulmonary artery pressure (PA) normally ranges between which values?

Pulmonary artery pressure is a critical measurement in assessing cardiovascular function, particularly in relation to pulmonary circulation. The normal resting values for pulmonary artery pressure typically range from 15 to 25 mmHg for the systolic pressure and from 8 to 15 mmHg for the diastolic pressure. This range represents the expected pressures needed to facilitate adequate blood flow from the right ventricle through the pulmonary arteries to the lungs, where oxygenation occurs. Maintaining pressures within this range is essential for optimal respiratory function and overall hemodynamics.

Values outside this range indicate potential cardiac or respiratory issues, making accurate knowledge of these pressures vital for patient assessment and treatment in critical care scenarios. Recognizing these normal values helps healthcare professionals identify abnormalities such as pulmonary hypertension or right heart strain, which could necessitate urgent intervention.
