ZOLL received this Award due to recent acquisitions and expansions to its resuscitation product line, coupled with an ability to demonstrate considerable insight into customer needs and product demands.Frost & Sullivan notes that ZOLL has several novel solutions that can help improve resuscitation efforts by enhancing emergency circulatory support during sudden cardiac arrest, which strikes 450,000 people annually in the U.S. According to Frost & Sullivan Analyst Nathan Cohen, “Later this year, the American Heart Association will update industry guidelines for cardiopulmonary resuscitation (CPR) and defibrillation, and it is expected to increase the focus on early CPR. Additionally, recent studies have reported the low quality of CPR being delivered in hospital and pre-hospital settings. By including real-time feedback on circulatory support in its line of products, ZOLL will not only improve its sales, but the company is prepared and positioned well to help revolutionize the quality and effectiveness of resuscitation in the healthcare industry.”“We believe that ZOLL has had remarkable success in the external defibrillator market in the face of strong competition,” said Richard A. Packer, President and Chief Executive Officer. “As a company, we have been focused on external defibrillation, which has been a key strength. We are now at a time in our company’s history where we can take that strength and broaden our reach to other areas of resuscitation. While providing industry leadership in this area takes significant investment, we believe it will pay big dividends in future growth.”Mr. Packer continued, “In many cases, the defibrillator was seen as the only device needed to solve the problem of improving survival from sudden cardiac arrest. However, as automated external defibrillators (AEDs) moved into the marketplace, data have shown that less than half of the people connected to an AED require an immediate defibrillating shock. The majority of the people need other therapies, in addition to defibrillation, to give them a reasonable chance of survival. Circulatory support, ventilation, and documentation and data management are all examples of technology needed to improve resuscitation outcomes. This Frost & Sullivan Award brings additional credence to our vision of improving the practice of resuscitation.”Frost & Sullivan made its selection based upon the following criteria:• Introduction of new products, strategically positioned to balance the product line;• Ability to accommodate different market segments, or different markets within an industry by repurposing technology;• Enhancement of product offerings through optimization of packaging, service, delivery, financing, and/or other value-added services; and• Strategic technology or marketing acquisitions or alliances.ZOLL has several products that provide rescuers with instantaneous feedback on the rate and depth of CPR chest compressions, which can help address emergency circulatory support during CPR. These products include the AED Plus,™ which is an AED designed for infrequent rescuers and first-responders, as well as the AED Pro,™ which was launched in 2004 for professional rescuers. Additionally, the ZOLL AutoPulse™ Non-invasive Cardiac Support Pump provides automated chest compressions in a unique, consistent “hands-free” manner. The AutoPulse offers the promise of circulating more blood to the heart and brain.(1-5) The automated, portable device is comprised of a backboard and a simple LifeBand™ that fastens across a victim’s chest.
