The Development and Application of Automated External Defibrillator

Abstract

Using Automated External Defibrillator (AED) to treat sudden cardiac death patients is recognized to be one of the most effective methods at present, and AED has been used widely in the United States, Japan, Britain and other countries, and some countries also had legislated to promote the installation of AED in public places. The development and application of AED in China later many years than in developed countries. This article mainly describes the development and application of AED in developed countries, which provide us reference to promote the development and application of AED in China. Index Terms - AED, sudden cardiac death, defibrillate I. Introduction Sudden death is one of the biggest challenges the medical profession facing this century, research data reveals that 75% of the sudden death patients are sudden cardiac death, (1) which is more acute onset, so it is very difficult to treat, and often result in the patient's sudden death, sudden cardiac death is a malignant disease threaten the health and lives of people. The survey data shows that the number people die from sudden cardiac death is 550,000 every year in China, and the proportion of young sudden death is increasing. More than 90% of the sudden cardiac death patients are ventricular fibrillation, if defibrillation is delayed one minute, the treatment rate will decrease by 7% to 10% (2), so early defibrillation is extremely crucial to the survival of sudden cardiac death patients. American Heart Association(AHA) has identified AED is the most effective method to treat sudden cardiac death patients at early time, and has been accepted by the public, and widely used in the United States, Japan and other countries. AED is designed to treat the cardiac arrest patient, and can be used easily by anyone, even if those never received medical training. Compared with the traditional emergency medical equipment, AED shows specific functionality and efficiency, it can quickly diagnose the patient"s heart rhythm, once diagnose with ventricular fibrillation, it will provide voice and demonstration screen guidance, and automatically deliver a shock to defibrillate.
