Considerable 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. ⋯ 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.

The outcome from cardiopulmonary arrest in children in the prehospital and hospital setting is generally poor. The event that compromises the cardiac status is often respiratory embarrassment, and the presenting rhythms are often bradyarrhythmias and asystole. Emergency medical services (EMS) systems have primarily an adult focus and may not be organized to manage optimally the critically ill and injured child. ⋯ There are two levels of receiving facilities: Emergency Departments Approved for Pediatrics and Pediatric Critical Care Centers. The system is voluntary and has 85% of the hospitals in compliance with the guidelines. Early recognition of the prearrest state, improved training, and equipping of prehospital care personnel, development of EMS services for children, dissemination of an advanced pediatric life support course, as well as research in pediatric CPR may improve the outcome of resuscitation in the pediatric population.
