Figure 2 Velocity Profiles at Baseline and During Hyperemia

Velocity profiles of the brachial and femoral arteries during systole at baseline (left) and at peak hyperemia (right) for the same younger subject as in Figure 1. Also shown are the parabola segments that are best fit to the datapoints near the arterial wall. Shear rate, the slope of the parabola segment near the arterial wall, is increased significantly during hyperemia.
