Advanced Life Support (ALS) is a treatment consensus for cardiopulmonary resuscitation in cardiac arrest and related medical problems, as agreed in Europe by the European Resuscitation Council, most recently in 2005. It is practiced by in-hospital cardiac arrest teams, which generally consist of junior doctors from various specialties (anesthetics, general or internal medicine). Emergency medical technicians (EMTs) are often skilled in ALS, although they may employ slightly modified version of the algorithm.
