Most bystanders who witness a cardiac arrest are willing to alert EMS but are not willing to initiate bystander rescue efforts because they are not willing to perform mouth-tomouth ventilation. Training and certification in basic life Pilares CCR Three Pillars of Cardiocerebral Resuscitation Table 1 Three Pillars of Cardiocerebral Resuscitation 1. CCC (compression-only cardiopulmonary resuscitation) by anyone who witnesses unexpected collapse with abnormal breathing (cardiac arrest). 2. Cardiocerebral resuscitation by emergency medical services (arriving during circulatory phase of untreated ventricular fibrillation [e.g., !5 min]) a. 200 CCCs (delay intubation, second person applies defibrillation pads and initiates passive oxygen insufflation). b. Single direct current shock if indicated without post-defibrillation pulse check. c. 200 CCCs prior to pulse check or rhythm analysis. d. Epinephrine (intravenous or intraosseous) as soon as possible. e. Repeat (b) and (c) 3 times. Intubate if no return of spontaneous circulation after 3 cycles. f. Continue resuscitation efforts with minimal interruptions of chest compressions until successful or pronounced dead. 3. Post-resuscitation care to include mild hypothermia (32°C to 34°C) for patients in coma post-arrest. Urgent cardiac catheterization and percutaneous coronary intervention unless contraindicated. CCC " continuous chest compression. n Cardiocerebral resuscitation was begun in November 2003 in Tucson, Arizona, and by 2007 was being used throughout the majority of the state. In 2005, the AHA updated their guidelines and incorporated some of the changes made with CCR (52). In 2008, the AHA published a science advisory statement supporting chest compressions only for bystander response to adult cardiac arrest (71). Table 3 compares current aspects of CCR with the AHA 2005 guidelines and their 2008 advisory statement. Uninterrupted perfusion to the heart and brain by CCC prior to defibrillation during cardiac arrest is essential to JACCneurologically Vol. 53, No. 2, normal 2009 survival. The low incidence of bystander-initiated resuscitation efforts in patients with cardiac January 13, 2009:149–57 arrest is a major public health problem. We have long advocated CCC CPR by bystanders as a solution to this critical issue because eliminating mouth-to-mouth “rescue breathing” will go a long way toward increasing the incidence of bystander-initiated resuscitation efforts. It is exciting to see that a technique (chest compression–only CPR) that had not been heretofore formally taught results in the same or better neurologically normal survival rates than those achieved with techniques taught for decades. CCR also changes the approach of those delivering ACLS. These changes resulted in dramatic (250% to 300%) improvement in survival of patients most likely to survive: those with witnessed cardiac arrest and shockable rhythm. More aggressive post-resuscitation care, including hypothermia and emergent cardiac catheterization and PCI, is required to save even more victims of sudden cardiac arrest.
