Everything You Need To Know About Buying An AED

We’re here to dive deep and answer all the questions that you have and the questions you don’t know you have! AED Source discusses everything you need to know about buying an AED for your workplace, business, group or training classes, including what to look for when purchasing an AED.

What is an AED? 

An automated external defibrillator is abbreviated and called an AED. Some people may call them just ‘defibrillators’ and that’s correct too but there are lots of different kinds of defibrillators used today.

Some people have implanted cardiac defibrillators that monitor their heart rate constantly and deliver a shock if needed. There are also wearable defibrillators that can be worn by people who are having their heart evaluated for risk of sudden cardiac arrest.

The most commonly known defibrillators are the ones in hospitals. In hospitals defibrillators are usually very large and operated manually with two hand paddles that are connected to a machine. Manual hospital crash cart defibrillators are what we see on TV most often. The main difference between hospital defibrillators and AED’s are that AED’s are automatic and do not require a medical professional to assess how large of a shock to give the victim or when to deliver the shock.

AED’s are very portable machines that are used in public settings and designed for use by anyone. AED’s are made to do all the work unlike manual defibrillators. Public AED’s will walk you through every step and assume no prior knowledge or experience with them. The only thing you have to remember to do is turn on the AED. Once you turn on the AED it will give you verbal directions of what to do. It will guide you to place pads and give visual diagrams that show proper pad placement. The voice instructions will tell you the next steps to complete and will inform you when to perform CPR. Most AED’s will give guidance on how to do CPR as well. These AED feature’s ensure that anyone can assist in an emergency.

Who can use an AED?

Anyone can use an AED. These machines are very safe and can do no harm. (Despite what you may have seen in movies) Some insurance policies or specific industries will require that people in their facility receive training on how to use an AED if they have one. However, regardless of training anyone can use an AED.

In advanced medical practice there is a term called ‘scope of care’ that implies you may only perform skills you are trained in. When it comes to using an AED, their use is within anyones scope regardless of training because they are designed to not need prior training.

What to look for when choosing an AED?

Some people purchasing an AED may have a specific reason. Some wish to travel with an AED and others want it for a private home, or public space. Depending on what you’re looking for there may be specific features to keep in mind.


The first thing to consider is an AED’s design. Most people want something very user friendly. There are some AED’s that excel at this and limit the number of directions the user has to follow. The Heartsine Samaritan AED would be an example of this. Other’s look for an AED that is designed to be easily spotted and identified like the electric yellow Zoll AED Plus.

Most AED’s come with ‘coaching’ that walks users through performing CPR and using the AED. However, if this is a feature you are looking for make sure to put it on your list.


Another consideration is the durability of the AED or its ability to withstand harsher environments. This would be important for people using an AED outdoors where the AED is exposed to dirt, sand, and water. All AED’s have an ‘IP’ (ingress protection) rating that is a universal measurement tool on the AED’s resilience to elements.

  • The first number, rates the level of protection the AED has against solids, like dirt and dust
  • The second number, rates the level of protection the AED has against moisture, like water

The higher each number is for an AED, the more protection the device has from these elements.

However, it’s important to note that IP Ratings have nothing to do with how well an AED can withstand a fall or stress from movement and vibration. For this, the Food and Drug Administration requires all AEDs to meet the same drop and shock standards.


When you choose an AED you will want to look at the accessories they require and how long these accessories last. Some AED’s have pads or batteries that are more expensive but last a longer time. Other AED’s have less expensive products but they need to be replaced as often as yearly at times. If your AED is in frequent use, such as one at a nursing home, you may opt to not worry about longevity of the pads and batteries but instead look for less expensive options to make the AED easier to upkeep regularly.


You will want to make sure you get an AED in the language you need. Some AED’s offer multiple language abilities and some have the ability to have other languages downloaded. Regardless, take note that the AED you purchase is in a language you speak.

What is normally included when buying a AED?

  • User Manual- All AED’s will come with a user manual that should be read and followed.
  • Cover or Case- AED’s are designed to be easily transported.
  • Battery- Most AED’s come with one battery but it’s recommended a spare battery be purchased as well.
  • Adult Pads- Most AED’s come with only adult pads. Some will also come with pediatric pads.
  • AED Source always includes one year free of AED program management with our AED’s.

How much do AEDs cost? 

AED’s pricing will varied based on the kind of AED as well as the accessories it comes with. Our AED’s range in price from $1,245 – $2,100 for the initial purchase. However, there is also an additional cost to maintain AED’s and make sure all parts are within their operation date. You can view our AED Comparison Chart to see the 8-year life cost of an AED with pads and batteries.

For an example, the most affordable AED is the Defibtech Lifeline and has an initial purchase price of $1,245 and an 8 year lifetime cost of $2,074. This AED is ever popular with rescue squads and fire departments because of it’s price and simple functionality.

The Heartsine Samaritan Pad 350 AED

Our favorite AED is the Heartsine Samaritan. This AED is the MVP. It has a low cost upfront and is oh so easy to maintain. Instead of having to purchase separate batteries and pads for this AED at various times, you simply have to replace the ‘Pad-pak’ (combo battery/pads) every four years. Additionally, the Heartsine Samaritan has one of the smallest footprints making it easy to transport.

The Cardiac Science Powerheart G5 AED

The Cardiac Science Powerheart G5 AED is one of the most high tech AED’s. This AED lives its best life when used by people with advanced medical training. While the AED can still be easily used by anyone the features it comes with are only going to be useful to trained medical responders.

The Physio Control LIFEPAK CR2

The Physio Control LIFEPAK is the most requested AED by schools and churches. This AED has dual language functionality that makes it popular in these environments that accommodate both Spanish and English speakers.  This AED also has unique technology that allows the user to continue CPR compressions while the AED analyzes the heart rhythm. Most AED’s don’t have this capability and the victim has several seconds of time lost where they could be receiving CPR to circulate oxygen through their body.

Is AED training required to use an AED?

We discuss this in detail in our article ‘Do You Need AED Training to Use an AED?’ While AED training is not required to use an AED, it is prudent to have people trained in using an AED so it can be quickly and efficiently used in the event of an emergency. It’s hard to imagine many scenarios worse than one where life saving equipment was available and not used. To find AED training in your area, we suggest using the Class Eagle Health & Safety Instructor Directory. On the directory you can find instructors that teach CPR & AED courses to suit your needs whether or not you are looking for basic AED training or advanced basic life support.

How do you install an automated external defibrillator?

While it is not necessary to install an AED, some places will choose to mount them or put them in a cabinet for protection or visibility. Installing these cabinets is usually relatively easy and only takes 2 screws. You will want to select a place that is easily accessible and visible. It’s important to install signage with the AED to let people know an AED is there. If the building you are installing an AED in has a safety team, you will want to discuss this with them and agree on the right position. For example, many churches or schools will think the entrance way is the best place to install an AED at first, but upon consideration they opt for a place that is more central in their buildings.

How much does an AED cost to maintain?

The cost of maintaining and AED varies on the AED and how often you use it. If you do not use an AED, there is still a cost to maintain it as the battery and pads will eventually expire. You will need to purchase the same brand of battery or pads that matches your AED for the AED to be functional. Please view our AED Comparison Chart to see the cost of accessories and cost to maintain over time.

What is the best AED for schools?

Every school should have an AED. While we often think of sudden cardiac arrest being more common in adults, it can also happen in children. Conversely, when children go into sudden cardiac arrest their chance for survival is so much greater with an AED. AED Source offers a handful of AED’s and we normally recommend the Heartsine Samaritan Pad 350 or the Physio Control Lifepak. We’d love to talk with you about what accessories you may need for your location as well.
