The ZOLL AED Plus continues to set the benchmark for design, dependability, durability, and performance. The AED Plus with its Real CPR Help technology is able to give real-time feedback on rate and depth of chest compressions during CPR. Only half of sudden cardiac arrest victims will initially need a shock, but all require high-quality CPR. The AED Plus supports rescuers with integrated text, voice, and visual prompts to help rescuers administer high-quality CPR.
