Pulmonary artery pressure

Home > Library > Miscellaneous > Wikipedia

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
Right ventricular pressure	diastolic	3–8
Pulmonary artery pressure	systolic	15–30
Pulmonary artery pressure	diastolic	4–12
Pulmonary vein/ Pulmonary capillary wedge pressure		2–15
Left ventricular pressure	systolic	100–140
Left ventricular pressure	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]
