This topic is from the Caring for Life First Aid and Self-Help Skills topic, which is described as follows:
The incorrect statement about AEDs is (D)A. Remove excessive chest hair from the patient before affixing the electrode pads.B. Do not use an AED in water or on surfaces of conductive objects such as metals.If the patient is lying in water, lift the patient out and dry the chest before using the AED.C. .Avoid applying electrode pads to the patient's implantable defibrillator, pacemaker, and medication patches.D.Place the electrode pads according to the instructions, and if the electrode pads are applied backwards, they need to be removed and reapplied.
AED is described in detail as follows:
1. Introduction: AED, also known as automated external defibrillator, automated shock device, automatic defibrillator, defibrillator, defibrillator, and shock device for dummies, etc., is a portable medical device, which can diagnose a specific cardiac arrhythmia and defibrillate it with an electric shock and is a medical device used by non-specialized personnel to rescue patients with sudden cardiac arrest. The device can be used by laypersons to resuscitate cardiac arrest patients. In the case of cardiac arrest, defibrillation and cardiopulmonary resuscitation (CPR) using an automated external defibrillator (AED) can only be performed during the "golden four minutes", which is the optimal time for resuscitation.
2. Effective first aid: AEDs are portable, easy to operate, and can be used skillfully with a little training, and are specifically designed for on-site first aid. In a sense, AEDs are not only first aid equipment, but also a new concept of first aid, a concept of effective first aid that can be performed by the earliest witnesses at the scene. It is different from the traditional defibrillator by the built-in computer to analyze and determine whether the patient needs to be defibrillated. During the defibrillation process, the AED's voice prompts and on-screen animation operation prompts to make the operation more simple and easy to carry out.
3. Adaptation of the patient: automatic external defibrillator, used when the injured person's pulse stops. However, it does not deliver a shock to a patient who has no heart rate and has a horizontally straight electrocardiogram. In short, the use of a defibrillator does not by itself restore the patient's heartbeat, as many movies and TV shows have misrepresented, but rather terminates the fatal arrhythmia by delivering an electric shock, and then restores the heartbeat by re-exciting the heart through a high cardiac pacing point to regain control of the heartbeat.
4. Usage: Unlike specialized defibrillators in hospitals, automated external defibrillators 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, and then it can determine and deliver the shock on its own.
