The ZOLL AED 3 is ZOLL's top-of-the-line model, and it shows. There's a high-resolution full-colour touchscreen that displays vivid rescue images, a CPR cycle timer, and a colour bar gauge showing compression depth in real time. Real CPR Help technology gives you live feedback as you're working, so you know if you're hitting the right depth and pace. RapidShock technology can analyze heart rhythm and deliver a shock in as little as five seconds, which matters when every pause counts. The same CPR Uni-padz electrodes work for adults and kids — just press the child-mode button and it adjusts energy automatically. WiFi connectivity lets the device monitor itself and send status updates remotely, which is handy if you're not checking on it regularly. IP55-rated for dust and water, five-year battery and pads, and a six-year warranty (extendable to eight). It also captures detailed rescue data through ZOLL RescueNet if you want to review what happened or share info with medical teams later.
