An automated external defibrillator (AED) plays a crucial role in increasing the chances of survival during a cardiac arrest. Studies have shown that the timely use of an AED, particularly within the first minute of the incident, can yield a remarkable success rate of up to 90%. This underscores the vital importance of having AEDs readily accessible in public spaces and promoting awareness about their use among laypersons. In critical situations, where every second counts, the swift application of an AED can restore normal heart rhythm and significantly improve patient outcomes. As such, initiatives to train individuals in CPR and AED usage are essential components of modern emergency response strategies. Ensuring that AEDs are available and that communities are educated on their operation can make all the difference in saving lives during cardiac emergencies.
