Pulmonary artery pressure

Pulmonary artery pressure: Pulmonary artery pressure (PA pressure) is a measure of the blood pressure found in the pulmonary artery. Mean pulmonary arterial pressure is normally 9 - 18 mmHg.^[1]

Site Normal
pressure range
(in mmHg)^[2]

Central venous pressure 3–8

Right ventricular pressure systolic 15–30

diastolic 3–8

Pulmonary artery pressure systolic 15–30

diastolic 4–12

Pulmonary vein/

Pulmonary capillary wedge pressure
2–15

Left ventricular pressure systolic 100–140

diastolic 3-12

It is usually higher than the pulmonary wedge pressure.

It can be elevated in sickle cell disease.^[3]

It can be used to measure pulmonary artery hypertension.^[4]
