Semi-Automated External Defibrillator

External defibrillators are essential emergency devices for defibrillation and cardiopulmonary resuscitation. Their principle is to use a strong pulse of electrical current through the heart to eliminate arrhythmia. The semi-automatic external defibrillator can be operated by automatic voice prompts, and can automatically identify the shockable rhythm and select the appropriate shock parameters. It can be deployed in emergency departments of hospitals at all levels, transportation hubs, schools, shopping malls and other densely populated public units.
