Figure 4From: Simultaneous mapping of temporally-resolved blood flow velocity and oxygenation in femoral artery and vein during reactive hyperemiaPost-occlusive time-courses of a) HbO 2 in femoral vein and b) average blood flow velocity in femoral artery after 3 mins of cuff occlusion. The red arrow indicates time-to-peak (TTP), the temporal location of the peak temporally-averaged velocity over a 2-second sliding window.Back to article page
