Defibtech Lifeline and Defibtech Lifeline Auto Review

The Defibtech Lifeline and Defibtech Lifeline Auto automated external defibrillators (AEDs) include all of the critical features needed to provide the most advanced treatment for sudden cardiac arrest. The user-friendly design is so simple that even non-medical personnel can effectively operate and potentially save a life with these AED machines.



Defibtech Lifeline Features

The Defibtech Lifeline AED was designed to be rugged and incredibly durable. This device’s award-winning design is made with the same construction and materials as a football helmet.

The Defibtech Lifeline AED comes in both fully automatic (Defibtech Lifeline Auto) and semi-automatic (Defibtech Lifeline).


With the Defibtech Lifeline Auto, after electrode pads have been correctly placed on the patient’s bare chest, the device will automatically analyze the patient’s heart rhythm and deliver a shock without the need for rescuers to intervene. The Defibtech Lifeline also automatically analyzes the patient’s heart rhythm. However, this AED has a red shock button labeled with a lightning bolt that when prompted needs to be pushed to deliver the shock to the patient.

Tested to military standards for shock and vibration, this AED’s lightweight design helps provide quick transport and easy rescue, while its ability to withstand dust and water ingress adds to its robust functionality.

Wes’s experience with the Defibtech Lifeline

Author: Wes Wagoner, EMT


Wes believes that Defibtech makes great AED machines at very attractive prices. He says, “Just because these devices aren’t as expensive as their competition doesn’t mean they aren’t as good! One of the unique features of the Defibtech Lifeline AED is the use of a 9V battery for its routine self-checks, ensuring the AED battery is fully charged if it is needed for a rescue.”


Wes continues, “The Lifeline AEDs also use LEDs instead of a less-vibrant LCD screen, which provide bright, clear visual guidance to reinforce voice instructions. Trust me, it can make a huge difference during a rescue!”
