A noninvasive, mobile assembly of devices intended to assist the blood circulation of an adult patient suffering from heart disease through the electrocardiogram (ECG) synchronized inflation of pressure cuffs worn around the extremities/buttocks. It includes an air pump with inflatable cuffs, ECG cables, a control unit or software for use with a personal computer (PC), and may include a pulse oximeter probe. The cuffs are intended to inflate from the most distal to the most proximal during diastole and deflate during systole to increase preload/decrease afterload. The system is intended to be operated by a professional in a clinical setting.
