Abstract
A method to increase the overall hemodynamic efficacy of cardiopulmonary resuscitation (CPR) by alternating between chest compression-decompression cycles optimized to either cardiac output or venous return. The phases of cardiac output and venous return enhancement may themselves by adjusted in their duration and character. The method may enhance mechanical and manual techniques delivered to the anterior or circumferential chest, and be synchronized to adjunctive techniques such as airway, ventilatory or abdominal therapies.
