Fully vs. Semi Automatic AEDs

It’s a question that makes a big difference when purchasing an Defibrillator – what is the difference between a Semi-Automatic and Fully Automatic AED?

Why do two versions exist?

Often, AED Manufacturers will produce both Semi and Fully Automatic versions of the same AED, as both versions present different advantages for different types of users.

The Fully Automatic AED

This device will analyze the patient's heart rhythm and then decide if it needs to administer a shock. If so, it will command the rescuer to Stand Clear, and then administer a shock automatically to the patient.  

Fully Automatic Devices were designed for public use. Often, untrained rescuers do not feel comfortable to administer a shock to a patient. A fully automatic device gives confidence to inexperienced rescuers, removing all the guesswork. Potential delays are also avoided, as the device doesn’t have to wait for the rescuer prompt to administer a shock.

The Semi-Automatic AED

This kind of device does pretty much the same thing as the former. It, too, analyzes the victims underlying heart rhythm, and detects whether it needs to administer a shock. However, instead of automatically shocking the victim, it prompts the rescuer to push the shock button in order to deliver the electrical impulse. This device is ideal for trained rescuers and paramedics, as it allows them to administer an electrical shock as they see fit, without waiting for the device prompts.

Which version should I buy?

When answering this, it is important to consider who will be using your AED, and its location.

How near is your device to a trained rescuer? What is the likelihood of people in my workplace having experience or training with AEDs?

As Semi-Automatic AEDs are tailored for the trained rescuer, they are perfect if you want to be in complete control of the environment surrounding the patient*. On the other hand, Fully Automatic AEDs help to reduce delays in administering when rescuers are untrained or unconfident– ideal for community wide or public use.
