Automated External Defibrillation

Defibrillation is the delivery of electrical current to the heart to restore a normal heartbeat. Defibrillation systems enable the detection and identification of life-threatening arrhythmias which can lead to death from Sudden Cardiac Arrest (SCA) and when appropriate, deliver a shock to restore the normal heartbeat. Sophisticated algorithms within defibrillators filter noise and artifact from a patient’s electrocardiogram signal to enable correct identification of heart rhythms that are life-threatening (i.e. shockable), or non-life-threatening (i.e. not shockable).

According to the American Heart Association (AHA) and European Resuscitation Council (ERC), an SCA victim requires defibrillation to stop ventricular fibrillation (VF), an often-fatal heart abnormality. Approximately two thirds of the estimated annual deaths from SCA occur outside a hospital in the United States. Almost 60% of these incidents are witnessed, yet 95% of these victims do not survive, according to the AHA.

Surviving SCA is linked directly to the amount of time between the onset of SCA and defibrillation shock. Following SCA, every minute without a defibrillation shock decreases chance of survival by approximately 10% - precisely why having your own automated external defibrillator (AED) to use while you're waiting for emergency medical responders is so important.

Communities that strategically place Automated External Defibrillators (AEDs) in public buildings, arenas, airports, and emergency vehicles reduce response times and, therefore, improve survival rates for SCA. Communities with public access defibrillation (“PAD”) programs report community survival rates approaching 50%. Numerous AED-related laws and regulations at the United States federal and state level and in some countries outside the United States have facilitated significant growth in both new and existing markets for AEDs.

Our patented Rescue Ready Powerheart® defibrillator family offers a variety of automated external defibrillator products for public use and medical professionals, alike. Our technology self-tests all main components and sets the Cardiac Science heart defibrillator apart from competitors. You’ll find the Cardiac Science automated external defibrillator in hospitals, offices, schools, restaurants, malls, airports, libraries, and public places – in short, just about any place someone could suffer sudden cardiac arrest.
