Description:

Flow volume is the product of flow velocity times the cross-sectional area of the slow steam. In a closed system, the volume of blood flow is the same inside and outside of a stenosed area (continuity equation). Thus the flow volume in the stenotic area should equal the flow volume in the area proximal to the stenosis.
