Defi5 Hospital Portable AED Automated External Defibrillator
An automated external defibrillator (AED) is a lightweight, portable device that delivers an electric shock through the chest to the heart. The shock can potentially stop an irregular heart beat (arrhythmia) and allow a normal rhythm to resume following sudden cardiac arrest (SCA).

Waveform details
The table below provides details of the biphasic truncated exponential waveform delivered by the DEFI5 (set to 200J) when connected to resistive loads of 25 through 175 Ohms. The waveforms are characterized by typical values for peak current (Ip), duration of the first output phase, and duration of the second output phase. Values are within 10%.
