CPR training involves teaching individuals how to perform cardiopulmonary resuscitation (CPR) in emergency situations where someone's heart has stopped beating. This training typically covers techniques for providing chest compressions and rescue breaths, as well as how to use an automated external defibrillator (AED) if one is available. CPR training is essential for healthcare professionals, first responders, and members of the general public, as prompt and effective CPR can greatly increase the chances of survival for someone experiencing cardiac arrest. Training programs may vary in length and content, but all aim to provide individuals with the skills and knowledge needed to respond quickly and effectively in emergency situations.
