Claim:
1. A pneumatic circulatory enhancer to enhance a blood flow of a leg of a patient, the pneumatic circulatory enhancer comprising: a chamber adapted to surround the leg and is filled with gas having a negative pressure, a zero-point pressure, or a positive pressure; a pneumatic gas pump having a cylinder and a piston that is connected to the chamber via a tube, the piston moving in the cylinder by an electrical motor; a plurality of ECG electrodes that are adapted to be connected to body parts of the patient and detect ECG signals, which are indicators of heartbeats of the patient, from the patient; a pressure sensor that is connected to the chamber and measures a pressure of the gas inside the chamber; a controller that receives the ECG signals from the plurality of ECG electrodes and controls the electrical motor based on the received ECG signals to pump-in/pump-out the gas to/from the chamber by moving the piston inside the cylinder, wherein the zero-point pressure is an atmospheric pressure that the pneumatic circulatory enhancer is operated, the negative pressure is any pressure smaller than the zero-point pressure, and the positive pressure is any pressure greater than the zero-point pressure.
