Zoll AED Plus is the first and only full-rescue AED (automated external defibrillator) on the market. Only half of victims will need a shock when sudden cardiac arrest occurs, but all will need CPR. The ZOLL AED Plus helps ensure you're prepared either way. This unit provides the user real-time feedback for depth and rate of chest compressions during CPR. Has a visible bar gauge on its display screen. Your AED will complete internal self-tests and will display a green check to show it is rescue-ready. Product Details: Has a five year shelf life.
