FOR IMMEDIATE RELEASE

GREEK AMBULANCE SERVICE COMPLETES STANDARDIZATION TO ZOLL MEDICAL RESUSCITATION EQUIPMENT

Thursday, August 12, 2004 – CHELMSFORD, MASS.—ZOLL Medical Corporation (NASDAQ: ZOLL), a manufacturer of resuscitation devices and software solutions, announced today that it has completed the inservice of resuscitation equipment to the Greek Ambulance Service, known as EKAV, operated by the Government of Greece. Under the exclusive contract through its distributor J. Ladakas, S.A., ZOLL has outfitted a total of 295 new ambulance vehicles, 25 fast-response motorbikes, and four local EKAV medical centers with a combination of ZOLL M Series™ and AED Plus™ defibrillators. In addition, 200 existing ambulances currently in service have been upgraded with ZOLL AED Plus defibrillators, bringing the total number of units deployed to 524.

Furthermore, in an earlier tender, J. Ladakas, S.A. has also supplied an additional 50 AED Plus units for the forthcoming Olympics in Greece. These defibrillators will be used to support the games taking place from August 13 to August 29, and will be distributed at certain public venues and operated by medical volunteers.

Commenting on these contracts, Richard A. Packer, President and Chief Executive Officer of ZOLL, said, “These were significant wins for ZOLL because our resuscitation equipment has now been deployed on all ambulances in the country of Greece. The exclusive agreement demonstrates EKAV’s belief in the strength and reliability of ZOLL’s resuscitation equipment. Additionally, the separate 50 AED Plus order will help prepare for sudden cardiac arrest events that may happen during the upcoming games. These units will be deployed in public venues, where approximately 150,000 people will attend daily. Having these units deployed may mean that victims of sudden cardiac arrest will receive appropriate treatment sooner, increasing the chance of survival.”

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 cardiac arrest victims that suddenly collapse 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 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 sudden cardiac arrest victim, making it the only Full-Rescue AED available today.
