"An international team of researchers looked at 49,555 out-of-hospital cardiac arrests that occurred in major U.S. and Canada cities. They analyzed a key subgroup of these arrests, those that occurred in public, were witnessed and were shockable. The researchers found that nearly 66 percent of these victims survived to hospital discharge after a shock delivered by a bystander." https://newsroom.heart.org/news/cardiac-arrest-survival-greatly-increases-when-bystanders-use-an-automated-external-defibrillator https://newsroom.heart.org/news/cardiac-arrest-survival-grea... Obviously, 66% beats the 10% survival rate in the original article (getting CPR alone from bystanders). The takeaway: AEDs can make a BIG difference. Curious that the article failed to mention that.
