A counterpulsation system for enhancing blood flow in a patient includes inflatable cuffs positionable on a leg of a patient. Three cuffs are preferably used for positioning on the calf, thigh, and buttocks. The cuffs are inflated in accordance with a timing sequence during diastole to enhance cerebral blood flow, and are then deflated. The process is repeated several times throughout a treatment session. A blood velocity sensor such as a transcranial Doppler (TCD) system detects cerebral blood flow velocity during treatment. The TCD output produces a first peak P 1 corresponding to the blood flow velocity during a contraction of the heart and a second peak P 2 corresponding to blood flow velocity resulting from the compression forces of the cuffs. If P 2 does not exceed P 1 , the timing sequence is manually or automatically altered to optimize the effect of the compression sequence during diastole.
