ABSTRACT:
The present invention provides a method and apparatus for improving the circulation of blood through a patient's heart and extremity. The method comprises applying external positive regional pressure on an extremity synchronously with the patient's heartbeat. An adjustable timing cycle is initiated at the QRS complex of the arterial pulse cycle. The timing cycle is based on an average time period between QRS complexes, which is calculated from a measurement of several successive QRS complexes in the patient's heart rate. Pressure pulses are applied in the end-diastolic portion of the arterial pulse cycle to reinforce the pulse that forces blood into the extremity. The pressure is then relieved prior to the next projected QRS complex to enable the next pulse to enter the extremity without undue obstruction, thereby promoting circulation of blood through the extremity. To promote circulation of blood through the heart, compression of the extremity is released shortly before the next projected QRS complex.
