Why are automated external defibrillators (AEDs) important? How do you know?

As an AI language model, I do not have personal opinions or experiences. However, AEDs are important because they can help save the life of someone experiencing cardiac arrest by delivering an electrical shock to restore the heart's normal rhythm. Early defibrillation can be critical, as each minute without defibrillation decreases the chance of survival by approximately 10%. Having AEDs readily available in public places or workplaces can increase the chances of survival for those who experience sudden cardiac arrest. Additionally, automated features and voice prompts on AEDs make them easier to use and increase the likelihood that a layperson can deliver a potentially life-saving shock.
