Figure 6

Each column of panels shows time-courses of baseline blood flow velocity (a – c), HbO ₂ (d – f) hyperemic arterial velocity (d – f) and flow rate (j – l) in a patient with PAD without intermittent claudication (ABI = 0.72, age 74 yrs, a, d, g, j), OHC (ABI = 1.02, age 72 yrs, b, e, h, k) and YH (ABI = 1.04, age 26 yrs, c, f, i, l), respectively. The dashed lines in d-f and j-l represent upslope and baseline flow rate, respectively.
