Sudden cardiac arrest (SCA) can strike at any time—during work, while at church, or in the middle of a school event. Without AEDs and CPR, the prospects for survival are bleak. Fewer than 10% of SCA victims typically survive, but studies show that 30% to 50% would likely survive if CPR and AEDs were used within five minutes of collapse.1 ZOLL® provides AED and CPR solutions for schools, fitness centers, churches, corporations, police stations, and other organizations that serve the public.1Sudden Cardiac Arrest Association, 2008 Public Safety Featured Products AED Plus® AED Plus - Fully Automatic AED Pro® PlusTrac™ AED Program Management The Importance of CPR FeedbackHigh-quality CPR is crucial to any rescue attempt.
