Example of DCS data acquired during brachial cuff occlusion in a representative subject. The dashed inset box is a magnified image of the time frame during POHR. The yellow box signifies the occlusion period as seen by the sudden BFI drop, and the blue arrow shows the data segment over which the BFI rate of change (dBFI) is computed over a given time interval (POHR = dBFI/dt).
