June 4, 2008 - Hands-only CPR AED Announced MEDIA CONTACT: Diane EganZOLL Medical Corporation+ (978) firstname.lastname@example.org Kim AngelastroPublicis Consultants / PR+1 (212) email@example.com ZOLL Offers First Hands-Only AED During First National CPR/AED Awareness Week June 4, 2008—CHELMSFORD, Mass.—ZOLL Medical Corporation (Nasdaq GS: ZOLL), a manufacturer of resuscitation devices and related software solutions, today announced that its AED Plus® with Real CPR Help® can be easily re-configured to support the Hands-Only protocol. The announcement was made in conjunction with the first annual National CPR/AED Awareness Week, June 1-7, which Congress has designated to spotlight how lives can be saved if more Americans know CPR and how to use an AED. In the declaration, Congress is asking states and municipalities to make AEDs more publicly accessible. This fully complies with the new American Heart Association Scientific Advisory released in April 2008, which calls for Hands-Only CPR to simplify saving lives for bystanders. The Hands-Only protocol means that during the two-minute CPR interval, only compressions should be delivered. Mouth to mouth breathing is no longer required. This is not a problem for the AED Plus because its Real CPR Help technology enables rescuers to see their compressions. It prompts the rescuer to “Push Harder” when compressions are too shallow and to speed up via a metronome to the recommended 100 compressions per minute. A re-configured AED Plus does not prompt the rescuer to do any breathing. When continuous compressions are being performed, the AED Plus guides the rescuer with beeps indicating the proper rate and a real-time bar gauge displaying the depth of every compression on the screen. “The ZOLL AED Plus is easy to use and can make the critical difference in bystanders reviving individuals who suffer from sudden cardiac arrest,” said Richard A. Packer, President and Chief Executive Officer of ZOLL. “Sudden cardiac arrest strikes people of all ages and fitness levels, usually without warning. Only about half need a shock, the rest need quality CPR.” Easily Configurable for Hands-Only CPR To make the AED Plus completely compatible with Hands-Only CPR, users need to access http://www.zoll.com/formtest.aspx?ekfrm=4130 and follow the download instructions. About the AED Plus AED Plus is the only AED that allows rescuers to see and hear how well they are performing the rate and depth of chest compressions during CPR. This real-time feedback mechanism, known as Real CPR Help®, makes the ZOLL AED Plus the only AED that can help assess and treat nearly every SCA victim, making it the only Full-Rescue AED available today. AED Plus is also the only AED with a one-piece electrode pad for easier positioning on the victim’s body (versus the traditional two pads, which can be challenging to place properly). AED Plus runs on consumer batteries that are easy to replace and last at least five years in stand-by mode. AED Plus requires minimal training to operate. The ability to analyze the heart’s electrical function is programmed into the device, and voice and text prompts guide rescuers through the appropriate CPR and defibrillation steps, as necessary. About Sudden Cardiac Arrest There are more than 325,000 deaths each year from out-of-hospital cardiac arrest in the U.S. Estimates say that more than half of these deaths occur suddenly. Currently, only about 5 percent of victims survive; 95 percent will die from SCA. SCA strikes without warning and can kill its victims within minutes. The American Heart Association estimates that focusing on a strong Chain of Survival (early access to care, early CPR, early defibrillation, and early advanced medical care) can increase survival rates to 20 percent or more, and could save at least 40,000 lives each year. SCA is an abrupt disruption of the heart’s function causing lack of blood flow to vital organs, which results in the loss of blood pressure, pulse, and consciousness. In nearly half of all victims, SCA is caused by an abnormal heart rhythm called ventricular fibrillation (VF). VF occurs when the nerves in the heart malfunction, causing the left ventricle (the heart’s main pumping chamber) to quiver or “fibrillate.” Stricken with this chaotic rhythm, the heart cannot effectively pump oxygenated blood to the brain and other vital organs throughout the body.
