Product Overview

The DualMax is an advanced, multifunctional cardioverter-defibrillator monitor designed for emergency cardiac care. It integrates multiple monitoring parameters and therapeutic functions into a single compact device, supporting biphasic defibrillation, AED mode, pacing, and comprehensive patient monitoring.

Main Features and Functionalities

• Biphasic Defibrillator: Delivers up to 360 J with energy adjusted to patient impedance; supports adult and pediatric modes.
• Automatic External Defibrillator (AED) Mode: Provides voice commands, visual cues, CPR instructions, and automatic shock delivery with multi-language support.
• Non-Invasive Pacemaker (NIP): Offers demand or fixed pacing modes with adjustable amplitude and frequency.
• Comprehensive Monitoring: ECG (up to 12 leads), respiratory rate, SpO2, non-invasive and invasive blood pressure, capnography (EtCO2), temperature, and ST segment analysis.
• Sudden Death Prevention (SDP) Technology: Continuous monitoring to detect ventricular fibrillation or rapid ventricular tachycardia episodes.
• CPR Maestro (Optional): Provides real-time feedback on chest compression depth and frequency to improve CPR quality.
• Smart User Interface: Touchscreen with adaptive display based on active parameters, quick access to key functions, and intuitive 1-2-3 command pattern.
• Portability and Durability: Compact, lightweight (5.15 kg device weight), IP55 protection, magnetized blades with quick coupler, and transport bag allowing device use without removal.
• Power and Battery: Dual removable Li-Ion batteries with charge indicators, supporting over 100 shocks or 7 hours monitoring per full charge; 4-hour recharge time.
