The ZOLL® X Series™ is the smallest, lightest, and most capable monitor/defibrillator on the market. Weighing less than 6 kg, the X Series is half the size and weight of competitive units. A large, bright screen allows simultaneous viewing of four dynamic waveforms, 12-lead ECG, or static and dynamic 12-leads. The X Series combines state-of-the-art and the most advanced monitoring technologies, such as the 'gold standard' Masimo® and Welch Allyn Rapid NIBP technology. The defibrillator provides unparalleled CPR support. The CPR Dashboard™ provides real-time feedback on CPR quality: chest compression depth and rate, and no-flow time. Chest relaxation and Perfusion Performance Indicators (PPI) also enhance CPR effectiveness. ZOLL's unique See-thru CPR® feature filters artifacts during CPR, minimizing interruptions needed for defibrillation. The X Series is the world's first monitor/defibrillator with a built-in WiFi module: Bluetooth® connectivity and a mobile USB modem are standard, and it also works with the RescueNet® Link EMS system. Created for combat and medical evacuation with helicopters and other aircraft.
