What does AED stand for?

AED stands for “automated external defibrillator.” It’s a portable medical device that’s used to assist sudden cardiac arrest (SCA) sufferers. The device analyzes the victim’s heart rhythm and can then deliver an electric shock to the heart if necessary.

Where can you find an AED device?

AEDs are often kept in public places including shopping malls, hotels, gyms, churches, and schools, private organizations of all types, and increasingly even in private homes. They’re often stored in a metal cabinet marked “Defibrillator.” If you’re looking to purchase a defibrillator for your home or organization, Response ready carries a wide selection of automated external defibrillators from all six FDA-approved manufacturers.

Can an untrained person use an AED?

AEDs can vary in their complexity. Advanced models like the ZOLL AED Pro are designed for emergency professionals, while user-friendly models like the Defibtech Lifeline View can be used by anybody. The good news is that almost every defibrillator contains voice and/or visual coaching that an untrained layperson can follow in an emergency. Learn more about AED training requirements in all 50 states.

What is an AED kit?

An AED kit or value package is a product bundle that contains the defibrillator, a first responder kit, a cabinet, a carry case, an assortment of signage, and often other useful accessories like a bleeding control kit. When you purchase this type of package, you receive everything you need to get your AED program up and running—all while saving money. Explore our full line of AED value packages.


How much does an AED device cost?

Depending on the features, a new automated external defibrillator typically costs between $1,100 and $2,500. Most models fall within the $1,400-$1,900 range. For those looking to save a bit more, refurbished AEDs are also available at a lower price point. To learn more about everything that factors into the price, check out our AED cost guide.

Can anyone buy an AED?

Yes – anyone can buy an AED. In the United States and Canada, anybody is permitted to purchase an FDA-approved defibrillator. These devices are subject to strict FDA premarket approval to ensure—in part—that a layperson can safely administer treatment in an emergency.

Do you need a prescription to purchase an AED?

It depends. Although prescriptions are still required at the Federal level, most AED manufacturers include a prescription in the box. The Philips OnSite is the only AED that can be purchased without a prescription, if placed in a private home. Some States also require ongoing Medical Oversight. For more information, check out our ‘AED Regulations by State’ in our Legal Center. Our ‘AED Total Solution’ program helps organizations of all types to meet these requirements easily and effectively.

Are AEDs covered by insurance?

Automated external defibrillators are typically not covered by insurance, though there are exceptions to the rule. Some insurance companies may cover the cost if you’ve suffered from cardiac arrest in the past or you have a condition that puts you at a heightened risk for sudden cardiac arrest, such as a history of ventricular fibrillation. You’ll need a physician’s recommendation before inquiring with your insurance company.

Is an AED tax deductible?

If you purchased an automated external defibrillator with a physician’s recommendation to address an existing medical condition, you can deduct the cost of the device as a medical expense. If you purchased the device for your business, you can deduct the cost as a business expense.


When should you use an AED?

An automated external defibrillator should only be used when a person appears unconscious and not breathing, with no apparent pulse.. This condition occurs when the heart suddenly stops beating. All AEDs will analyze the patient’s heart rhythm once applied, and only initiate a shock or activate the shock button if indicated, so users of an AED can rest easy knowing there is no way to accidentally shock a person with a beating heart.

When should you NOT use an AED?

Do not attempt to use an automated external defibrillator on someone having a heart attack who is still conscious. These devices should only be used on cardiac arrest sufferers, presenting as unconscious victims who are not breathing, or only gasping. Other conditions include not using an AED on someone who has a pacemaker, is lying in a body of water, or has a verified DNR. To learn more, refer to our guides on when not to use a defibrillator and the differences between heart attack and cardiac arrest.

Can an AED be used on anyone?

Defibrillators are suitable for cardiac arrest sufferers of all ages. If a person is submerged in water, move them to a dry location and quickly dry their chest before applying pads and providing treatment. If the victim has a pacemaker, you can still administer treatment but must place the pad about an inch away from the pacemaker. If the victim has a “Do Not Resuscitate” (DNR) tattoo or bracelet, you should avoid administering treatment.

Can you use an AED on a baby?

Yes. When treating a baby, always start with CPR chest compressions. Push down on the center of the chest at a depth of about 1.5 inches, or ⅓ the depth of the chest. Set the defibrillator to its pediatric setting, or attach the pediatric pads. If no pediatric pads are available, you can use adult pads. Just make sure that the pads don’t touch one another. One pad should be placed on the center of the baby’s chest, and the other on the center of the baby’s back.

What are the steps to using an AED?

  1. Press the “On” button, or open the lid to activate the device.
  2. Place the pads on the patient’s chest according to the diagram on the back of each pad.
  3. Follow the audible instructions provided by the defibrillator.
  4. Administer shock only if instructed.

Learn how to use an AED device in greater detail.

Where do you place AED pads?

Attach one pad to the right side of the chest, directly beneath the collarbone. Attach the other pad to the lower left side of the chest.

Can an AED shock the rescuer?

Electrical shock may occur if you touch the patient during defibrillation. When the pads are attached to the patient and the device is delivering shock, you will be audibly instructed to “stand clear.” Don’t touch any part of the patient until the shock has been delivered and you’re instructed that it’s safe to continue treatment.

Can you use an AED on a conscious person?

No. An AED should only be used on a cardiac arrest sufferer who is unconscious and not breathing. Defibrillation can be extremely dangerous when performed on a conscious person. Fortunately, all AEDs will analayze a patients heart rhythm, and only initiate a shock or activate the shock button when indicated, preventing the shocking of a conscious victim. For more information, refer to our guide on when not to use a defibrillator.


Do AED machines expire?

When an AED reaches 10 years old, it’s generally considered time to replace it. Electrical components age over time, and technology also improves with each passing year. In addition, the pads and batteries each have their own expiration date. Your machine should alert you when one of your components is nearing its expiration date, but be sure to monitor those dates independently as well.

Do AEDs require maintenance?

In addition to monitoring your expiration dates, you’ll need to ensure constant readiness of your defibrillator by adhering to all legal requirements. These requirements vary from state to state but may include regular inspections and medical oversight. By signing up for AED program management, you can receive the assistance and updates you need to ensure that you’re always in compliance. Learn more about AED maintenance here.

Can an AED be stored outside?

An outdoor defibrillator should be stored in a sturdy AED cabinet. This will prevent the battery from prematurely deteriorating in extreme temperatures. Most automated external defibrillators meet MIL-SPEC standards of ruggedness and are therefore equipped to withstand rough environmental conditions and moisture, but manufacturers still recommend avoiding prolonged exposure to the elements. This will ensure that it always operates flawlessly at a moment’s notice.

Where do you install an AED?

When installing an AED in the home, keep the device in a visible area that’s easy to access. If the defibrillator needs to emit any warning alerts due to a low battery or malfunction, you’ll know right away. If installing the defibrillator for public use, place it in a common area that’s visible and unobstructed. Each device should be stored in its own cabinet. Learn where to install your AED device.

What height should an AED be mounted?

An AED should be mounted no more than 48 inches above the floor. This will ensure that it’s within reach of most individuals in an emergency, including wheelchair-bound responders.


Can I get in trouble for using an AED?

As long as the device is used in an emergency situation on a patient who is unconscious and appears to be not breathing, you should not face any personal liability. Even if the patient doesn’t survive or has a DNR, Good Samaritan laws should protect you from legal recourse in almost every instance.

How long do AED pads last?

A typical set of pads will last between 18 and 30 months from the time of manufacture. A few select models, like the ZOLL CPR-D-Padz, may last up to five years.

Will an AED tell you to stop CPR?

An AED will instruct you to stop CPR and stand clear if the patient requires an electrical shock. If the patient remains unconscious after a shock is administered, you will be instructed to resume CPR for another 2 minute cycle, until the AED again promts you to pause while it re-analyzes the patients rhythm. Continue to follow the prompts and perform CPR when indicated until emergency services arrive. This will ensure that the patient receives blood flow to vital organs while the heart is stopped.

How many amps does an AED have?

There are two types of AED: those offering escalating shocks (with increasing intensity) and those that offer non-escalating (or fixed) energy shocks. An escalating defibrillator may deliver a shock at 200 Joules, and then a second at 300 Joules, and a third at 360 Joules. Many fixed energy defibrillators shock at 150 Joules, but vary the wavelength based on patient impedance. Total joules delivered, the waveform of the energy, and the impedance of the patient all play important roles in the effectiveness of the shock. While the debate surrounding which shock delivery method is most effective has continued for decades, the important take-away is that all FDA approved AEDs have been shown to be effective in delivering life-saving defibrillation in sudden cardiac arrest.
