The AED Pro features a high-quality display for ECG monitoring with standard ECG electrodes. It is the only professional defibrillator to use ZOLL’sCPR-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.
