SECTION 1: Introduction
Description The Responder 2000 is a defibrillator/monitor/pacemaker intended for use by personnel trained in its operation. The device is lightweight, portable, easy to use and reliable. It incorporates a 320 x 240 transmissive color TFT color display for wide viewing angles in all light conditions. The device operates using either an AC power supply or internal rechargeable Li-Ion battery. The device provides continuous ECG monitoring and three types of therapies: defibrillation, cardioversion and external pacing. Defibrillation can be applied manually or semi-automatically. Pacing therapy can be ® ® either fixed or demand. The device employs patented RHYTHMx software which provides ECG rhythm analysis. STAR Biphasic waveform delivers impedance-compensated energy ranging from 2-270 Joules. Features and options include external paddles, spoons, disposable pads, 3- and 5-lead ECG, pulse oximetry (SpO2), built-in 60 mm thermal printer, internal storage of event history and remote synchronization to bedside monitor.
