AbstractConsiderable effort has been expended in recent years by a number of laboratories to improve methods of cardiopulmonary resuscitation. This article briefly summarizes 5 years of investigation by our group on hemodynamic support during external cardiac massage. In most studies, long-term canine preparations were used, and implanted transducers allowed precise hemodynamic measurements. Although cardiac output was depressed with all CPR methods, manual chest compressions of high velocity, moderate force, and brief duration at a rate of 120/min seemed to optimize systemic and coronary blood flow. This method was termed high-impulse CPR. High-impulse techniques now have been applied extensively in the clinical setting, and preliminary observations also support their efficacy in man. Based on this experience, it is suggested that the American Heart Association guidelines be changed to recommend a manual chest compression rate of 120/min during closed-chest cardiac massage.
