ViVest A1 semi-automatic AED with pictogram guidance
The ViVest A1 is a slim, lightweight defibrillator that guides the rescuer through every stage of a cardiac arrest response. Loud voice prompts are supported by an illustrated front panel and LED indicators, so it’s clear where to place the pads and what to do next, even under pressure.
At just 1.5kg with a built-in carry handle, it’s easy to take to the casualty quickly, and its IP55-rated housing is tough enough to be used without a carry case.
