Early defibrillation is a critical component in treating sudden cardiac arrest, and ZOLL® offers automated external defibrillators (AEDs) to meet the needs of a full range of lay rescuers, first responders, and hospital professionals. When sudden cardiac arrest occurs, the fact is that only half of the victims will need a shock, but all of them will need high-quality cardiopulmonary resuscitation (CPR). Our AEDs include Real CPR Help®, which provides real-time CPR feedback on the depth and rate of chest compressions. It's all part of an extensive and integrated line of defibrillation solutions designed to advance the practice of resuscitation.
