Pulmonary Vascular Resistance = 80 * (Mean Pulmonary Artery Pressure - Pulmonary Artery Wedge Pressure) / Cardiac Output

English Name: Pulmonary Vascular Resistance (PVR)

Normal Value Range: 120–250 dynes*s/cm⁵

The resistance to blood flow during pulmonary circulation. It arises from the frictional resistance between the flowing blood and the vessel walls, as well as the internal friction of the blood. It is related to blood viscosity, vessel length, elasticity, and vessel radius.
