For patients with sudden cardiac death, about 70% occur outdoors. First aid is given to the patients within 4 min after onset. The survival rate of the patients can reach 50%. For every 1 min delay, the successful rescue will drop by 7% ~ 10%. Ambulances are often difficult to reach the scene within 4 minutes. Therefore, it is urgent to improve AED and configure AED.
