Boston-Based Teradyne, Inc. Chooses ZOLL Defibrillators for Global Early Defibrillation Program



Monday, December 19, 2005 – CHELMSFORD, MASS.—ZOLL Medical Corporation (NASDAQ: ZOLL), a manufacturer of resuscitation devices and software solutions, announced today that Boston-based Teradyne, Inc. (NYSE: TER), a supplier of automatic test equipment and interconnection systems, has chosen ZOLL’s AED Plus™ automated external defibrillator (AED) for deployment in Teradyne facilities in 15 countries, effective immediately.

In addition, Teradyne has chosen En-Pro, Inc. (formerly ZOLLMD), a company affiliated with ZOLL, to provide the design, implementation, and ongoing management of the company’s AED program. En-Pro will also train Teradyne employees at all sites to act as first responders in the event of an emergency. Teradyne’s worldwide deployment is one of the most comprehensive AED programs undertaken by a New England-based company. Teradyne expects to have all of the AEDs deployed by the end of December 2005.

“Safeguarding the health and safety of our employees is of primary importance to us, and ensuring that we provide a work environment that can deal with emergencies is a key part of that,” said Loren Eaton, vice president of Human Resources at Teradyne. “We believe that this product offers the best protection possible against sudden cardiac arrest in the workplace.”

New American Heart Association guidelines, released in November, recommend that AED programs should be implemented in public locations, such as businesses, where there is a relatively high likelihood of witnessed sudden cardiac arrest (SCA).

“Teradyne joins a growing list of Fortune 1000 companies that see the value of not only implementing a global early defibrillation program, but also committing the resources to do so,” said Richard A. Packer, president and chief executive officer of ZOLL. “By deploying this technology worldwide, Teradyne is taking a leadership role that we hope more companies will follow.”

When a victim collapses from SCA, 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 victims who suddenly collapse initially require defibrillation. For other victims who may have non-shockable heart rhythms, the critical action for survival is effective CPR.

The ZOLL AED Plus is the first and only AED that helps 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 SCA victim, making it the only Full-Rescue AED available today.
