The Defibtech Lifeline AED is available as either the base model, or with a display screen, or with an ECG reading for professional responders. The base model is available in both automatic, and semi-automatic options. With an automatic model, there is no button to administer a shock. The AED will analyze the patient’s heart rhythm and administer a shock if viable. In a semi-automatic model, the AED will analyze the patient’s heart rhythm, and if appropriate to shock the patient, the device will light up a flashing button to be pushed by the rescuer, which will then administer a shock. Both options are excellent choices and choosing automatic vs. semi-automatic is a matter of preference.

The Lifeline View has a full colour LCD Display which plays step-by-step instruction videos for AED use and performing CPR. The Lifeline ECG model has the same instructional video display and has the additional option of displaying the patient’s ECG data, should a trained medical responder be available on scene. Additionally, the Lifeline ECG model can be used for monitoring of a patient’s heart rhythm by trained medical professionals, even if the patient is not in cardiac arrest.

In order to maintain the AEDs compact, easy to carry design, the pads will be attached to the device, and then stores in a sealed pouch on the rear of the machine. Pediatric pads do not typically come equipped with the Lifeline but are available to purchase separately. Pediatric pads are recommended to be used on individuals less than 8 years old, or under 55 lbs.

All AED pads contain an adhesive gel coating, which allows the pads to stick to the surface of the patient’s skin, and this also conducts the shock being transmitted. Due to the possibility of this adhesive gel drying out in the long term, all pads come sealed in a package and have an expiry date. In the case of all Lifeline models, the pads have a 2-year shelf life.

All Lifeline AEDs run self-diagnostic checks daily, weekly and monthly. There is a green indicator light which will flash if the device is in proper working order. If the device detects any issues, the indicator light will flash red or stop flashing, and the machine will periodically emit an audible beep. If this should happen, please consult the user manual in order to troubleshoot.

There are two battery options available for purchase that are compatible with the standard model of Lifeline defibrillator. There is a battery that is set to expire 5 years after installation, which can deliver 125 consecutive shocks or work continuously for 8 hours. Defibtech also offers a longer lasting option, which has a 7-year standby life. This is the longest lasting battery currently available on the public Canadian market. It can last for 300 shocks or work continuously for 16 hours. The Lifeline View and Lifeline ECG each have a standard 4-year battery life.

When registering with the Heart Safe AED website, you will enter important information into the database such as battery and pad expiry dates, so you can easily track when they will need to be replaced.

These devices also feature data download options, as the device records heart rhythms and other valuable data when it is being used. This data can be downloaded onto a computer and utilized by First Responders and Medical Professionals to determine the nature of the issue and assess treatment options. Please refer to the manufacturer’s website below to find out more.

The Lifeline is priced between $1500-$2500, depending on the model. Consider the cost and frequency of replacement pads and batteries when evaluating AED purchase options.
