Cuff occlusion paradigm shows the following: (a) Cross-sectional images of the femoral artery that were used to draw regions of interest before (rest) and after cuff occlusion (at three different time points) to determine flow mediated dilation; (b) Femoral vein oxygen saturation (SvO2) plotted vs time after cuff release. SvO2 is derived from the difference between venous and arterial signal phase. (Tw = washout time); and (c) Average blood flow velocity-time curve in the femoral artery. (HI = hyperemic index; Vp = peak velocity; Tp = time to peak velocity; TFF = time of forward flow)
