There are many unpredictable cardiac incidents that have occurred and were connected to ventricular fibrillation where a sudden spasm and arrhythmia happen in the lower chambers of the heart. When ventricular fibrillation happens during a heart attack, an automated external defibrillator can shock the heart so that it go back to its normal pace. Automated external defibrillators can be defined as lightweight and portable devices featuring a computer that can review the cardiac rhythm of an individual and deliver an electrical charge whenever it is necessary for the survival of the patient. As soon as automated external defibrillators recognize that there is a disturbance with the conductive system of the heart of the patient, it immediately delivers an electrical shock. In this article, we will provide some general information about automated external defibrillators. Automated external defibrillators, also referred to as AEDs, usually have the size of a textbook. They are powered by a battery and feature two adhesive sensors that are connected by power lines to the main device. After they have been activated, automated external defibrillators supply audible voice commands that speak to the patient and guide them through the proper positioning of the sensors, the activation of power, and the shock procedures if required. From the point of view of the principle, both AEDs and manual defibrillators are alike. Effectively, the sensors monitor the rhythm of the heart in order to find out whether or not delivering an electrical charge is necessary, and provide the adequate shock whenever it is needed. According to a report published by the American Red Cross, the support of automated external defibrillators can help preclude about fifty thousand cardiac arrest fatalities. Any medical facility that possesses automated external defibrillators on site does not have to deal with the necessary time to restore normal heart functions while waiting for proper medical assistance. In terms of the prevalence, it is probably true to state that AEDs are increasingly becoming the basic requirements in health and fitness facilities, in offices, in hospitals, in schools, in doctor's offices, in department stores, and in many other public venues. Individuals also have the option to buy them for their house or apartment as well. In practice, very few professionals possess the knowledge to perfectly use automated external defibrillators. Indeed, only the individuals who have earned a certification in both cardiopulmonary resuscitation and automated external defibrillators can best use these devices. Yet, as we stated earlier in the text, AEDs provide audible voice commands that can talk to any person through the process in an emergency situation. There are two kinds of automated external defibrillators: semi-automatic AEDs and fully automatic AEDs. Semi-automatic external defibrillators necessitate that the rescuer push a button in order to deliver the electrical charge. On the other hand, fully automatic eexternal defibrillators send an electrical shock independently to the intervention of any lifesaver. A mono-phasic defibrillator delivers a single electrical shock from one chest pad to the other. While a biphasic defibrillator sends a single electrical shock between chest pads. One of the benefits that comes with using biphasic defibrillators is that they can adjust energy based on the resistance between the chest pads, which ultimately allows to prevent the occurrence of any major damage to the heart. Ventricular fibrillation can be defined as a cardiac condition in which the heart receives appropriate electrical energy but in a disorganized way. Ventricular fibrillation has the ability to hinder the muscle of the heart from contracting and pumping blood. Ventricular tachycardia can be defined as a condition in which the heart is beating too rapidly. This condition does not permit the chambers of the heart to fill with sufficient blood, which ultimately provokes an insufficient circulation of the blood in the entire body.
