When should an Automated External Defibrillator (AED) be used?

An Automated External Defibrillator (AED) should be used as soon as it is available, after calling emergency services. The timely use of an AED is critical in cases of sudden cardiac arrest, as it can significantly increase the chances of survival by restoring a normal heart rhythm. Early defibrillation, ideally within the first few minutes of cardiac arrest, is essential because for every minute that passes without defibrillation, the chance of survival decreases significantly.

Using an AED promptly helps in delivering a shock to the heart when it is in a life-threatening rhythm, such as ventricular fibrillation or pulseless ventricular tachycardia. It is important to prioritize the use of the AED quickly while ensuring emergency services are notified so that professional help is en route.

In situations where a victim is unresponsive or not breathing normally, utilizing an AED should not be delayed. While CPR is vital and should be performed until the AED is available, it is not necessary to wait for a specific time frame of CPR to be completed before applying the AED. Thus, the main priority is to get the AED as soon as possible and attach it to the victim; the device provides audible instructions on when to deliver a shock, ensuring effective action can be taken without unnecessary delay.
