How to Check Your Defibtech Lifeline Defibrillator is Ready

Checking a Defibtech Lifeline AED is quick and straightforward. The status indicator light shows green when the unit has passed its self-test and is rescue-ready, and red when attention is required. Each device performs automatic daily, weekly, and monthly self-tests covering internal circuitry, battery condition, and pad connectivity, all without user input.

On the Lifeline VIEW, the always-on status screen displays battery and pad readiness, including expiry date alerts, without the unit needing to be powered on. As part of routine maintenance, confirm electrode pads are within their expiry date, verify the battery indicator, and inspect the unit for physical damage. Genuine replacement Defibtech pads and batteries are available from DefibWarehouse for fast, straightforward restocking.

How to Use a Defibtech Defibrillator

Every Defibtech Lifeline AED is designed to guide any user, trained or untrained, from the moment it is switched on. In an emergency:

Press the green on/off button. Voice prompts begin immediately; on the Lifeline VIEW, full-motion video instructions appear on screen at the same time.
Remove or cut away clothing from the patient's chest and ensure the skin is dry before applying the pads.
Attach the pre-connected electrode pads to the bare chest following the placement diagrams. The device analyses the heart rhythm automatically.
Fully automatic models deliver the shock without user input. Semi-automatic models instruct the rescuer to stand clear and press the illuminated shock button.
After shock delivery, the AED guides CPR with voice prompts and a metronome to maintain the correct compression rate.

With just two controls (on/off and shock) the Lifeline AED is instinctive under pressure. The Lifeline VIEW adds full-colour video coaching at every step, giving any bystander the clarity to act decisively.

Why Choose a Defibtech Defibrillator?

Defibtech defibrillators are designed and manufactured in the USA to exacting medical standards and US military specifications: lightweight, durable, and straightforward to operate. The Lifeline VIEW stands apart as the only AED in the world with full-motion colour video guidance, a genuine innovation that removes the barriers to confident action for any bystander.

An 8-year device warranty, long-life battery options, and automatic self-testing make the Lifeline range a low-maintenance, high-performance investment. With over 650,000 units shipped worldwide, the track record speaks for itself.
