    What is an AED?


    An automated external defibrillator (AED) is a portable defibrillator that checks a person’s heart rhythm and delivers a shock if the AED determines the patient has a shockable rhythm such as irregular heart rhythms, or ventricular fibrillation. If a person suddenly collapses and stops breathing, they may be suffering from sudden cardiac arrest (SCA) and SCA is serious. It means a person’s heart has stopped pumping blood and they need help fast in order to restore their heart to a normal rhythm or SCA can be fatal.

    The most important element in the treatment and aid of SCA is not only CPR (cardiopulmonary resuscitation), but to provide a rapid electrical shock to their heart called defibrillation. An AED device helps ordinary people to provide defibrillation quickly to help save lives. HeartStart AEDs are the only AED (automated external defibrillators) approved by the FDA for sale over the counter without a prescription.

    How do I use an AED?


    Philips portable defibrillators 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 until emergency services can arrive. Replacement AED supplies, such as electrode pads, batteries and accessories are available online if you use your AED in an emergency.

    Defibrillator one

    Pull the handle to activate the AED

    HeartStart AEDs arrive with the Adult SMART pads cartridge and battery already installed and is positioned inside the carry case. After you set up the device, simply pull the handle to activate your defibrillator.

    Defibrillator two

    It guides you through every step

    Once you pull the green handle to activate the AED, voice instructions will guide you through the entire process – from placing the electrode pads on the patient to performing CPR and delivering electrical therapy.

    Defibrillator three

    AED delivers fast shock therapy

    This medical device features patented Quick Shock, which typically administers a shock just eight seconds after CPR, making the OnSite among the fastest in its class at delivery treatment after CPR. Studies show that minimizing time to shock after CPR may improve survival.1-4
