CPR and AED training are two different steps in the process of saving the life of someone suffering from cardiac arrest. The acronym “CPR” stands for cardiopulmonary resuscitation, which is the act of repeatedly compressing a person’s chest in order to keep their blood pumping throughout their body. CPR acts like a manual heartbeat, keeping vital organs alive even after the heart has stopped beating. While many people are already familiar with CPR, its counterpart often goes unnoticed. Most classes are actually offered as CPR AED training, or at least explain the use of the AED in the course of their instruction. “AED” stands for automated external defibrillator and there is a big difference between CPR and AED training even though both are usually covered in the same class.
