The ideal first response to a life-threatening pediatric emergency includes early recognition of the emergency, activation of the appropriate emergency response system, performance of basic life support (cardiopulmonary resuscitation/automated external defibrillator treatment), and initiation of advanced life support, but the extent of resuscitation training among health care providers likely to be first at the side of a critically ill or injured child is often deficient. In the past, resuscitation courses beyond basic life support focused on training advanced providers. The Pediatric Emergency Assessment, Recognition, and Stabilization course was developed by the American Heart Association to target a broad range of health care providers who are likely to be first at the side of a child requiring resuscitation. It is hoped that training of health care providers through the Pediatric Emergency Assessment, Recognition, and Stabilization course will translate into early recognition of life-threatening pediatric emergencies and greater resuscitation success, but results will depend on the availability of instruction and the maintenance of skills.
