    What is an AED?


    An automated external defibrillator (AED) is a device that checks a person’s heart and delivers an electric shock if it has stopped beating normally. If a person suddenly collapses, they may be suffering from sudden cardiac arrest (SCA) and SCA is serious. It means that the person’s heart has stopped pumping blood and they need help fast.

    The most important element in the treatment of SCA is to provide a rapid shock to their heart called defibrillation. An automated external defibrillator (AED) helps ordinary people to provide defibrillation quickly.

    How do I use an AED?


    When you observe someone suffering from a suspected SCA, you need to act quickly. Philips AEDs come equipped with integrated SMART Pads. Just place the SMART Pads on the person’s bare skin and the pads will provide feedback to the AED so calm, step-by-step voice instructions can guide you through the entire process of using the AED.

    When you pull the green handle to activate the AED, voice instructions will guide you through the entire process – from placing each pad on the patient to performing cardiopulmonary resuscitation (CPR) and delivering a defibrillation shock.*1

    Patented Quick Shock typically administers a shock just eight seconds after CPR, making the OnSite among the fastest in its class at delivering shock treatment after CPR. Studies show that minimizing time to shock after CPR may improve survival. *2-5

    When do you need to use an AED?


    Sudden cardiac arrest (SCA) is a condition in which the heart suddenly and unexpectedly stops beating. If this happens, blood stops flowing to the brain and other vital organs. SCA usually causes death if it's not treated within minutes by an AED.

    When do you need to use an aed?


    SCA is not the same as a heart attack. A heart attack occurs if blood flow to part of the heart muscle is blocked. During a heart attack, the heart usually doesn't suddenly stop beating. SCA, however, may happen after or during recovery from a heart attack.


    You don't need to remember this distinctions as when the Philips AED instructs you to put the pads on the victim, it will sense the heart rhythm and determine the best steps to take, giving you guidance all along the way.
