Does an AED Increase the Chance of Survival?

Having an AED available significantly increases the chances of surviving a heart attack, particularly a Sudden Cardiac Arrest (SCA). Here's a breakdown of the difference:

    • Without an AED: Survival rates for out-of-hospital cardiac arrest are very low, around 7% to 9%.
    • With an AED: Studies show a dramatic improvement. Bystander use of an AED can increase survival rates to 38% or even higher.

Here's a more specific breakdown:

    • Early defibrillation is crucial: The chance of survival decreases by about 10% with each minute that defibrillation is delayed [1]. An AED can analyze the heart rhythm and deliver a shock if necessary, potentially restarting the heart.
    • AEDs are user-friendly: They are designed for bystanders with little to no medical training to use. The AED provides clear voice instructions to guide the user through the process.
    • Time is critical: Studies suggest that 9 in 10 SCA victims who receive a shock from an AED within the first minute survive [2].
