About AEDs

EmergencyKits.com carries AED machines from ZOLL, Cardiac Science, and HeartSine for workplaces, schools, public access sites, and homes. Every AED on this page talks the rescuer through each step of a rescue with voice and visual prompts, gives real-time CPR feedback, and can be used on children with the manufacturer's pediatric pads.

Choose a fully automatic AED that delivers the shock on its own, or a semi-automatic model where the rescuer presses the shock button when the AED advises it. Connected HeartSine models also report readiness over Wi-Fi, so you know your AED is ready before it's needed. Need replacement pads, batteries, cabinets, or trainers? Contact us and we'll help you find parts that fit your device.

Frequently Asked Questions

Shop AED machines from ZOLL, Cardiac Science and HeartSine for workplaces, schools and homes, with real-time CPR feedback and pediatric capability.

What is an AED?

An AED is a portable, battery-powered device that checks the heart's rhythm and delivers an electric shock when it detects a rhythm that needs one. AEDs are built for bystanders with no medical training: once the pads are on the person's chest, voice and visual prompts guide the rescuer through each step, including CPR. The Cardiac Science Powerheart G5, for example, uses RescueCoach voice and text prompts paced to the rescuer.

What does AED stand for?

AED stands for Automated External Defibrillator. "Automated" means the device analyzes the heart rhythm and decides whether a shock is needed, "External" means it works through pads placed on the chest, and "Defibrillator" means it delivers the shock that can restore a normal rhythm.

What is an AED used for?

An AED is used to treat sudden cardiac arrest, when the heart's electrical system fails and it stops pumping blood. A shock from an AED can stop the abnormal rhythms that cause most cardiac arrests, ventricular fibrillation and pulseless ventricular tachycardia, so the heart can return to a normal rhythm. Using an AED along with CPR within the first few minutes gives the person the best chance of survival. AEDs with CPR feedback, like the ZOLL AED Plus and the HeartSine samaritan PAD 450P, coach the rescuer on compressions until help arrives.

What is AED certification?

AED certification shows that a person has completed a CPR and AED training course from an organization such as the American Heart Association or the American Red Cross. Certification is usually valid for 2 years. It isn't required to use an AED in an emergency, but many workplaces and schools require it for designated responders.

What does an AED do?

Once the pads are on the person's chest, the AED analyzes the heart rhythm. If it detects a rhythm that needs a shock, a fully automatic AED like the HeartSine samaritan PAD 360P or the Cardiac Science Powerheart G5 delivers the shock on its own, and a semi-automatic AED tells the rescuer to press the shock button. If no shock is needed, the AED prompts the rescuer to continue CPR.
