What is considered a normal pulmonary artery pressure?

The normal pulmonary artery pressure is recognized as being within the range of 10-20 mmHg for the systolic value and 0-4 mmHg for the diastolic value. This reflects the pressure exerted by the blood within the pulmonary arteries as it carries deoxygenated blood from the right ventricle to the lungs. When assessing pulmonary artery pressures, understanding the normal ranges is crucial for evaluating heart and lung function, as abnormal values can indicate a variety of pathophysiological conditions, such as pulmonary hypertension or heart failure.

The other ranges presented do not align with this standard definition, making the selected option the most accurate representation of normal pulmonary artery pressures.
