The ZOLL AED Semi-Automatic is a complete AED which is a fit for multiple environments. When a cardiac arrest occurs, the fact is that only half of the victims will need a shock. But nearly all will require cardiopulmonary resuscitation (CPR). You deserve an automated external defibrillator (AED) that helps you all the time. And, only one AED can actually see when you are doing CPR and help you do it well. You need more than just commands, without assistance. That’s not smart, and it’s certainly not help. ZOLL’s AED Plus features Real CPR Help, a CPR feedback tool that is able to actually see what you are doing and provide feedback to help you do it well. Audio and visual prompts help you rescue with confidence and clarity unmatched by any other AED. Not pushing hard enough? It will tell you when to push harder. Pushing hard enough? It will say, “Good compressions.” Not pushing fast enough? A metronome will lead you to the right rate. It will even show you the depth of each compression. In real time. Not yet started? The AED Plus will tell you again to get started. Compressions stopped? It will tell you to continue. The AED Plus is now available as a fully automatic AED. ZOLL believes AEDs should not just deliver a shock. They should also help the rescuer provide high-quality cardiopulmonary resuscitation. That’s why you need ZOLL AEDs, the AED Plus with Real CPR Help. The AED Plus offers a one-piece electrode pad for fast and accurate placement. Our AEDs use consumer lithium camera batteries available from retail stores. Other important features include Intelligent Pediatric Capability, ZOLL’s Rectilinear Biphasic Waveform and ability to follow Guidelines 2010.
