When it comes to saving lives in the event of sudden cardiac arrest, an AED (Automated External Defibrillator) can make all the difference. But with many options available, selecting the right type of AED can be overwhelming. Should you choose a public access AED or a professional model? What’s the difference between semi-automatic and fully automatic devices? And which features matter most depending on where and how the AED will be used?
In this blog post, we’ll walk you through the different types of AEDs, their intended uses, and the most important factors to consider before making your decision. Whether you’re outfitting a school, workplace, gym, or public space, this guide will help you find the AED that fits your needs.
What does an AED do?
Before diving into types, it’s helpful to understand what an AED actually does. When someone suffers sudden cardiac arrest, their heart may stop beating effectively due to a dangerous rhythm. An AED analyzes that rhythm and, if necessary, delivers an electric shock to reset the heart. When used quickly and correctly, an AED can dramatically increase the chances of survival.
Devices like the Philips HeartStart OnSite AED and Philips HeartStart FRx AED are excellent examples of how AEDs have been engineered for simplicity and accessibility, even for people with no medical experience.
Two main AED categories
There are two broad categories of AEDs, based on who they’re designed for:
Public access AEDs
These AEDs are meant for use by everyday people; teachers, office staff, security guards, or even bystanders. Public access AEDs are often found in places like airports, schools, fitness centers, restaurants, and corporate buildings. Their key features include:
-
Clear voice prompts and visual instructions
-
Fully or semi-automatic operation
-
Lightweight and portable design
-
Shock delivery only if needed
Public access models, like the HeartStart OnSite AED, are made to guide users through each step, making them ideal for environments where trained responders may not be present. These AEDs can be stored in clearly visible cabinets for quick access during emergencies.
Professional AEDs
Professional AEDs are designed for trained emergency personnel such as paramedics, firefighters, or healthcare providers. These models typically include advanced features like:
-
ECG display for monitoring heart rhythm
-
Manual override functions
-
Customizable energy levels for shock delivery
-
Data recording and integration with EMS systems
Though they offer more control, professional AEDs require training and are better suited for medical or rescue teams who understand complex cardiac rhythms.
Fully automatic vs semi-automatic AEDs
Another key difference between AED models is how the shock is delivered. This determines whether the user presses a button or the device does it on its own.
Fully automatic AEDs
Fully automatic AEDs assess the heart rhythm and, if a shock is required, deliver it without any input from the user. This makes them perfect for high-stress environments where hesitation could cause delays. These AEDs are simple, intuitive, and reduce the burden on the rescuer.
Semi-automatic AEDs
Semi-automatic AEDs guide the user through every step and instruct them to press a button to deliver the shock if one is needed. Some organizations prefer this option because it gives the responder a sense of control over when the shock is applied.
Both versions are safe, effective, and easy to operate. Choosing between them depends on your setting and user preference.
Matching AEDs to environments
When selecting an AED, it’s essential to consider the setting where it will be used. Different environments may call for specific features:
-
Schools and childcare settings: Choose a model with pediatric pads or a built-in child mode, such as the Philips HeartStart FRx AED.
-
Outdoor or industrial locations: Look for rugged, weather-resistant AEDs that can handle temperature extremes and rough conditions.
-
Offices and retail stores: Opt for compact, easy-to-store units with automatic functionality.
-
Remote locations: Ensure long battery life and clear prompts for users with little to no medical experience.
Want complete readiness? Our AED packages include the device, pads, batteries, carry case, cabinet, signage, and optional add-ons like bleeding kits. Everything arrives in one shipment so you’re ready from day one.
Add bleeding control for full emergency response
In many emergencies, it’s not just cardiac arrest you’re dealing with. Serious injuries like trauma or severe bleeding can happen anywhere. For full preparedness, many customers choose to combine AEDs with a Bleeding Control Kit – Standard or the Premium version, which includes additional supplies like hemostatic gauze, trauma shears, gloves, and emergency blankets.
Bundling a bleeding kit with your AED helps create a response station that’s ready for nearly any medical emergency.
How to choose the right AED
To determine which AED is right for you, ask the following:
-
Who will be using the device, trained professionals or the general public?
-
Will the AED be installed indoors, outdoors, or carried around?
-
Is simplicity more important, or do you need more advanced features?
-
Would fully automatic or semi-automatic operation be more effective for your team?
If you’re still unsure, our complete AED packages simplify the process. They contain everything you need for quick installation and ongoing use.
Be ready with the right AED
There’s no one-size-fits-all solution when it comes to AEDs. The best AED for your environment depends on who will be using it, where it will be located, and what features you value most. By understanding the different types of AEDs, you can confidently choose a device that gives people the best chance of survival in a cardiac emergency.
