Advanced Cardiac Life Support.

In brief Changes in the advanced car-brief diac life support guidelines in-elude a new classification system for interventions, training in the use of automated defibrillators, and required early defibrillation for ventricular fibrillation. The algorithms for treating ventricular fibrillation and pulseless ventricular tachycardia, pulseless electrical activity, and asystole are reviewed. Cardiac arrest caused by special circumstances-hypothermia, near drowning, trauma, and electrical injuries-presents additional treatment considerations.
