ViVest A3 semi-automatic AED with colour screen
The ViVest A3 combines clear voice prompts with a 5-inch colour screen that shows each step of the rescue as an animation with text. Seeing and hearing the instructions together helps rescuers act quickly and correctly, and makes the A3 a strong choice for noisy environments or users who are hard of hearing or visually impaired.
A language button lets the rescuer change the prompts between up to three languages, which is useful in multilingual workplaces and busy public spaces.
