What is an Automated External Defibrillator

The so-called automated external defibrillator (AED), or AED, is a portable, easy-to-operate, a little training can be skilled in the use of first aid equipment designed for on-site first aid, in a sense, the AED is not only a kind of first aid equipment, but also a first aid is a new concept, a kind of first aid by the first on-site witnesses to the concept of effective first aid. It is different from the traditional defibrillator which can be analyzed by the built-in computer and determine whether the patient needs to be defibrillated. During the defibrillation process, the AED's voice prompts and screen display make the operation easier and simpler. AEDs can be operated by most people with only a few hours of training.

Unlike specialized defibrillators in hospitals, AEDs require only a short period of instruction to use. The machine itself automatically reads the electrocardiogram and decides whether a shock is needed. Fully-automated models even require only that the rescuer apply a shock patch to the patient before it determines and delivers the shock. Semi-automatic models remind the rescuer to press the shock button. In most cases, the machine will not deliver a shock even if the rescuer pushes the button by mistake. Some models can be used on children (under 25 kg or under 8 years of age), but they must be equipped with child-specific electrode patches. The American College of Cardiology suggests that even if a pediatric patch is not available, an adult patch can be used instead; there is no evidence that adult patches cause more serious damage.

Currently, many areas of the country are trying to deploy AEDs in public ****ing places, but the country's understanding of them and the actual use of them is not high.
