The statement about AED is wrong: (d) A. The patient's excessive chest hair should be pulled out before the electrode is attached. AED should not be used on the surface of conductive objects such as water or metal. If the patient is lying in the water, he should be carried out first and his chest should be dried before using the AED. C avoid sticking electrode pads on patients' implantable defibrillators, pacemakers and drug patches. Position the electrode plate according to the instructions. If the electrode plate is pasted upside down, it needs to be removed and pasted again.
The detailed description of AED is as follows:
1. Introduction: automated external defibrillator, also known as automated external defibrillator, Automatic Defibrillator, Automatic Defibrillator and Idiot Defibrillator, is a portable medical device, which can diagnose specific arrhythmia and give electric shock defibrillation, and can be used by non-professionals to rescue patients with cardiac arrest. In the case of cardiac arrest, automated external defibrillator (AED) is only used for defibrillation and cardiopulmonary resuscitation within the "golden 4 minutes" of the best rescue time.
2. Effective first aid: automated external defibrillator is a portable, easy-to-operate and skilled first aid equipment, specially designed for on-site first aid. In a sense, AED is not only a kind of first-aid equipment, but also a new first-aid concept, a concept of effective first-aid by witnesses at the scene. It is different from the traditional defibrillator, and the built-in computer analyzes and judges whether the patient needs electric defibrillation. During defibrillation, AED's voice prompt and screen animation operation prompt make the operation easier.
3. Adapt to the patient: automatic external cardiac defibrillator, used when the pulse of the injured person stops. But it will not cause electric shock to the injured with unintentional heart rate and horizontal straight ECG. In short, the use of defibrillators can not restore the patient's heartbeat, which is misleading in many film and television programs. Instead, the fatal arrhythmia is terminated by electric shock, and then the heartbeat is controlled again through the excitement of high pacing point, so that the heart can resume beating.
4. How to use: Unlike professional defibrillators in hospitals, automatic external cardiac defibrillators can only be used after short-term teaching. The machine itself will automatically interpret the electrocardiogram and then decide whether an electric shock is needed. In the fully automatic mode, even if the rescuer puts an electric shock patch on the patient, it can judge and generate an electric shock by itself.
