This chapter outlines an approach towards the resuscitation of pediatric patients adapted from the 2010 American Heart Association (AHA) guidelines for cardiopulmonary resuscitation and emergency cardiovascular care. Pediatric basic life support (BLS) encompasses prevention, early cardiopulmonary resuscitation (CPR), and prompt access to the emergency response system, and these latter two components pertain to the practitioner providing sedation. In infants, one should check for a brachial pulse, and in children, a femoral or carotid pulse. Pediatric advanced life support (PALS) builds upon BLS and relies on a team of organized healthcare providers working effectively, rapidly, and simultaneously to resuscitate a patient. The PALS cardiac arrest algorithm organizes care around 2-minute periods of uninterrupted CPR. If a patient's ECG rhythm is shockable, defibrillation should occur immediately after the last compression and CPR should begin again with chest compressions immediately following delivery of the shock.
