Current Approaches to Cardiopulmonary Resuscitation *

Real progress has been made in improving long-term outcome after out-of-hospital cardiac arrest in the past 10 years. Many communities have doubled their survival-to-hospital-discharge rate during this period. Common features of such successful programs include the following: (1) 911 dispatcher-assisted cardiopulmonary resuscitation (CPR) instruction, (2) bystander chest compression–only CPR program, (3) public access defibrillation, including targeted automated external defibrillator programs, (4) renewed emphasis on minimally interrupted chest compressions by emergency medical services responders, and (5) aggressive postresuscitation care, including targeted temperature management and early coronary angiography and intervention. An important lesson from these successful community efforts is that multiple, simultaneous changes to the local cardiac arrest response system are necessary to improve survival. The next exciting step in this quest appears to be the treatment of refractory cardiac arrest with the combination of mechanical CPR, intra-arrest hypothermia, extracorporeal CPR with mechanical circulatory support devices, and early coronary intervention.
