The ZOLL M Series is only 11 pounds and has everything needed for cardiac resuscitation: fast, easy to use defibrillation; external pacing; ECG with advanced monitoring; built-in AC or DC power; and an integrated information management system. Straightforward controls, intuitive menus and ZOLL's Uniform Operating System make operation simple and reduce staff training. A high-contrast screen, with improved readability and wide angle of view is superior to any LCD display. A full range of models are available, from manual to advisory and AED to meet all needs and are fully upgradeable to keep pace with changing demands.
