When the patients face the incidence of serious arrhythmia, it is always the case that there is  different degree of hemodynamic disorder. The most serious and most common situation is ventricular fibrillation, when the ventricular is without the whole contractility and the heart terminates blood ejection and blood circulation. If not rescued on time, it results in the death of patients due to long time brain hypoxia. At this moment, it should be promptly carried out the  defibrillation by defibrillator, so as to let certain energy of current flows pass through the heart to eliminate heart rhythm disorders, to restore normal heart rhythm and to gain the time for further saving.

The original defibrillator used the industrial alternating current directly to eliminate the defibrillation. This type of defibrillator often killed or injured due to electric shock. As the technology increasingly completes, AED already possesses reliable analytical techniques of heart rhythm and reliable discharge method, which can improve the defibrillation effect and reduce the damage to the human body.

The AED operation is usually divided into three steps: start, paste electrodes as well as the proposal whether to conduct electric shock or cardiopulmonary resuscitation. AED will automatically collect and analyze the heart rhythm also give the instruction to perform electric shocks. Whether it will occur mistaken electric shock, the key is if the reliability of the rhythm analysis and that of the discharge method. As long as these two points are done, in general, it will not happen mistaken electric shock. Moreover, AED will present clear instructions before conducting electric shocks. It will warn you whether to conduct the electric shocks, only after the button is pressed, it will produce.electric shocks. In any case, AED is such a tool: through the safe electric shock to reach the purpose of first aiding cardiac arrest patients.
