A defibrillator is a medical device used to treat cardiac emergencies, specifically cardiac arrest caused by ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). It delivers an electric shock to the heart to restore a normal heartbeat.

Cardiovascular diseases are a significant public health concern in Mexico. According to the World Health Organization (WHO), cardiovascular diseases are responsible for over 30% of all deaths in Mexico. Cardiac arrest can occur anywhere, and having a defibrillator nearby can significantly increase the chances of survival.
