WebOct 11, 2024 · Pulmonary Vascular Resistance . Four factors influence blood flow in the lung: pulmonary vascular resistance (PVR), gravity, alveolar pressure, and the arterial to venous pressure gradient. Blood flows through the pulmonary circulation in a pulsatile manner following the pressure gradient in this low resistance system.
