Tuesday, June 08, 2004 – CHELMSFORD, MASS.—ZOLL Medical Corporation (NASDAQ: ZOLL), a manufacturer of resuscitation devices and software solutions, today announced a three-year, sole source contract with Universal Health Services, Inc. (UHS), one of the largest hospital management companies. This contract authorizes ZOLL’s direct sales force to sell its complete line of defibrillators to all UHS facilities, which have already purchased more than 150 ZOLL defibrillators to date.

With approximately 26,000 employees, UHS operates more than 100 medical facilities in the U.S., Puerto Rico, and France. UHS consists of behavioral health hospitals, acute care and ambulatory facilities, and radiation centers. “We require medical devices that clearly demonstrate an ability to improve the quality and outcome of patient care,” said Clark Saylor, Director of Purchasing for UHS. “The significant clinical support ZOLL provided for its products contributed to the decision to award ZOLL this sole source contract."

“Centralizing the purchasing process with UHS streamlines our sales cycle and builds on the success of our M Series™ defibrillators,” said Richard A. Packer, President and Chief Executive Officer of ZOLL. “It also allows us to further expand the market for our automated external defibrillator, the ZOLL AED Plus™. The AED Plus, which is suitable for clinical and non-clinical settings, meets the needs of any early defibrillation program and better prepares UHS facilities for sudden cardiac arrest wherever it may occur.”

When a victim collapses from sudden cardiac arrest, rescuers do not know whether defibrillation or CPR is the appropriate therapy until an AED is attached and the victim’s heart is analyzed. About half of all sudden collapsed victims initially require defibrillation. For other victims however, who may have non-shockable heart rhythms, the critical action for survival is effective CPR.

The ZOLL AED Plus is the only AED that help rescuers perform effective CPR because it allows them to see and hear how well they are performing the rate and depth of chest compressions during CPR. This real-time feedback mechanism makes the ZOLL AED Plus the only AED that can help assess and treat nearly every sudden cardiac arrest victim, making it the only Full-Rescue AED available today.
