FOR IMMEDIATE RELEASE


ZOLL Displays Advanced Resuscitation Products at EMS Expo 2005



NEW ORLEANS  Thursday, August 25, 2005 – --ZOLL Medical Corporation (NASDAQ: ZOLL), a manufacturer of resuscitation devices and software solutions, is displaying its advanced resuscitation products in Booth #1100 at EMS EXPO 2005, which is taking place August 25 through August 27 in New Orleans.

First EMS Unveiling of the ZOLL E Series Defibrillator

Building on the well-established ZOLL M Series™, the ZOLL E Series™ meets the demands and extreme conditions of EMS. It is the only defibrillator to pass a
4-foot drop test and features:

• A suitcase-style design with an innovative, protective roll cage, allowing users to carry or store the device easily

• An EasyRead Tri-Mode Display™ for use in pitch dark or direct sunlight, providing superior readability and complete views of critical patient information at virtually any angle

• A built-in GPS clock, allowing customers to automatically synchronize all of their dispatch, defibrillator, and intervention call times, improving overall data accuracy

• A Rapid Cable Deployment System™ that helps manage all the parameter cables, allowing for faster deployment and avoiding the “spaghetti in the bag” that can be associated with other defibrillators

Additional ZOLL Products On Display at EMS EXPO 2005


• The AutoPulse™ Non-invasive Cardiac Support Pump provides the potential of normal blood flow levels during sudden cardiac arrest.(1,2) It is comprised of a backboard and a simple load-distributing LifeBand™ that fastens across a patient’s chest and moves more blood, more effectively.(1,2,3,4,5)

• The ZOLL AED Pro® offers advanced capabilities for Basic Life Support (BLS) users, and provides AED capability with manual override for Advanced Life Support (ALS) users. The AED Pro features a high-quality display for ECG monitoring with standard ECG electrodes. It is the only professional defibrillator to use ZOLL’s
CPR-D•padz™ electrode, which measures the rate and depth of chest compressions during CPR, and provides visual and audible feedback on this performance. ZOLL is the first in the industry to provide this real-time feedback capability.

• The ZOLL M Series™ monitor/defibrillator can be configured to include multiple monitoring parameters and operating modes. With a lifetime-limited warranty on the Respironics® EtCO2 module, the M Series was the first defibrillator to offer plug-and-play mainstream and sidestream EtCO2 monitoring options, so users can select the optimum CO2 monitoring method for their clinical applications.

• RescueNet™ is a suite of software products sold by the ZOLL’s subsidiary ZOLL Data Systems. It provides EMS customers with a single data management system that integrates dispatch, resuscitation information from ZOLL’s line of defibrillators, field data collection, billing, and clinical quality assurance functions. Two new RescueNet products on display will be TabletPCR™ and RescueNet Crew Scheduler. TabletPCR helps eliminate paper processes, while helping users to meet HIPAA requirements and improve efficiency. Crew Scheduler allows EMS personnel to improve the process of scheduling through a web interface and an ability to model any type of shift combination.
