Apparatus for promoting blood circulation in a body part suffering from a circulation deficiency by inflating and deflating a pressure cuff applied to a patient's limb proximal to the affected body part so that the blood is forced into the affected body part. The apparatus is synchronized with the patient's heartbeat by way of an EKG pickup and automatically compensates for the blood transit time from the heart to the point of cuff application. The apparatus includes control means responsive to the sensing of the blood flow at a location distal to the cuff for achieving optimum blood circulation in the body part being treated.
