Defibrillation is the process of terminating heart fibrillation using medical devices or specific drugs. In medicine, the term "defibrillation" usually refers to the use of a defibrillator to terminate ventricular fibrillation by discharging electricity into the heart.
Defibrillation can be divided into three categories according to different methods:
1. Electrical defibrillation - defibrillation through defibrillator discharge;
2. Drugs Defibrillation - defibrillation by injecting drugs to affect the electrical activity of the heart;
3. Manual defibrillation - percussion in the precordium;
Among them, the most commonly used and most effective method It is electric defibrillation, which is listed as the highest recommendation in the CPR and Cardiovascular Emergency Guidelines.
Electrical defibrillation is a method of terminating ventricular fibrillation by shocking the heart with a certain amount of current. It is an effective method to treat ventricular fibrillation. Today, direct current defibrillation is the most widely used method.
The original defibrillator used industrial alternating current for direct defibrillation. This kind of defibrillator often caused casualties due to electric shock. Therefore, currently, alternating current is used for internal defibrillation during cardiac surgery (ventricular defibrillation). Except for fibrillation), direct current defibrillation is generally used.
Extended information:
In terms of emergency rescue, the most effective is AED defibrillation, that is, automatic external defibrillator.
Automated external defibrillator, also known as automatic external shock device, automatic electric shock device, automatic defibrillator, cardiac defibrillator and fool electric shock device, is a portable medical device that can diagnose specific It is a medical device that can be used by non-professionals to rescue patients with sudden cardiac death.
Automatic AED is easy to operate and can be used skillfully with a little training. It is a first-aid equipment specially designed for on-site first aid. In a sense, AED is not only a first-aid equipment, but also a new first-aid equipment. concept, a concept in which effective first aid is provided first by witnesses at the scene.
Different from traditional defibrillators, it can analyze and determine whether the patient needs electric defibrillation through a built-in computer. During the defibrillation process, the AED's voice prompts and screen display make the operation simpler and easier. An automated external defibrillator can be operated by most people with just a few hours of training.
