Why can you resuscitate someone else?

You can resuscitate someone else because you have the ability to perform life-saving techniques, such as cardiopulmonary resuscitation (CPR) or using an automated external defibrillator (AED), which can restore breathing and circulation. Understanding the physiological processes behind cardiac arrest allows you to intervene effectively. Additionally, by acting quickly, you can help prevent brain damage and increase the chances of survival until professional medical help arrives.
