[News in basic life support and semi-automated external defibrillation].

During resuscitation, basic life support (BLS) and automated external defibrillation refer to maneuvers designed to maintain airway patency and support breathing and circulation without equipment other than a barrier device and the use of an automated external defibrillator (AED). We present some of the most important developments incorporated to the new international recommendations for resuscitation 2010. Aspects related to prevention and early detection of cardiac arrest are highlighted, along with the important role of dispatchers of emergency medical services, the importance of high quality CPR and programs of public access defibrillation. We likewise describe sequences of action and basic life support algorithms, and semi-automated external defibrillation.
