This document provides guidelines for cardiopulmonary resuscitation (CPR). It discusses: 1) CPR techniques for adults, children, and infants with an emphasis on high quality compressions that are started within 10 seconds of arrest, are at least 100 compressions per minute for adults and children or 120 for infants, and are at least 5 inches deep for adults or 1/3 the depth of the chest for children and infants. 2) The routine use of cricoid pressure during CPR is no longer recommended and pulse checks should be limited to 5-10 seconds with compressions started if any doubt about a pulse. 3) For infants, manual CPR is preferred to automated CPR from
