The Defi Xpress is an automated external defibrillator (AED) with an ECG monitor. It features AED functions and prompts, alarm selection and limits, and delivered energy. It provides heart rate and SpO2 information, and shows Biphasic waveform (takes less than 7 seconds with a new fully charged battery).
The device has a 7" (17.7 cm) diagonally high-resolution screen with a 25mm/sec sweep speed and shows both selected and delivered energy. It also has voice and visual prompts, and 0-250 ohms electrode impedance measurement range.
For ECG monitoring, Defi Xpress features a 3- or 5-lead ECG cable patient connection and paddles. Heart rate range is 20-300BPM. ECG lead selection (I, II, III, aVR, aVL, aVF, V), and ECG sizes (0.25, 0.5, 1, 1.5, 2, 4 cm/mV) are shown on the monitor. The user-selectable On/Off heart rate smart alarm enables beeps/voice prompts in cases of shockable rhythm.
The Defi Xpress runs on a 12V rechargeable Ni-MH battery. For a new, fully charged battery, 60 defibrillator discharges at maximum energy or 3 hours minimum of continuous ECG monitoring. Additional parameters with different functions affect operating time.
