Cardiac life support refers to a set of emergency procedures used to restore normal heart function in individuals experiencing cardiac arrest. This includes techniques such as cardiopulmonary resuscitation (CPR) and the use of an automated external defibrillator (AED). These methods aim to maintain blood flow and oxygen delivery to vital organs until professional medical help arrives. The primary goal of cardiac life support is to prevent brain damage and increase the chances of survival. Training in these techniques is essential for both healthcare professionals and laypersons, as timely intervention can significantly improve outcomes for individuals in cardiac distress.
