Description

The present invention relates to a defibrillator, and more particularly, to an automated external defibrillator (AED) system.

In general, heart disease is the leading cause of death. For example, an arrhythmia caused by a problem in the electrical system of the heart becomes an abnormal heart rhythm (arrhythmia). The most serious arrhythmia is ventricular fibrillation (VF), which can suddenly stop the heart from pumping blood. This causes the patient to lose consciousness in a very short time. Pulseless ventricular tachycardia (VT) and bradycardia can also lead to sudden cardiac arrest.

Sudden cardiac arrest is usually unpredictable. When these occur, the patient's heart stops, stops breathing, and loses consciousness. If this event lasts for more than 5 minutes, the patient's survival rate falls below 50%. Therefore, immediate cardiopulmonary resuscitation (CPR) and defibrillation are necessary to prevent death and permanent damage.

Therefore, a defibrillator that is easy to carry and easy to use is desired.

The present invention provides an automated external defibrillator (AED) and system thereof that is easy to carry and use.
