Drugs and Pulmonary Perfusion
The relationship between flow and pressure in the pulmonary circulation is non-linear and because the flow is high and the pressure is low, subtile changes in pressure may reflect quite profound changes in vascular properties. Principal among these properties is vascular tone, which is a functional concept representing the net State of the vasculature after all of the forces, both active and passive, have interacted.
