¿Qué es un Desfibrilador Externo Automático (DEA)?


If you’re wondering what an AED is, and why Cardiac Science wants them to be as common as a fire extinguisher, it’s not the only one. At the center of our mission to convert environments such as work centers, schools, and communities safe sites for the heart, more people than ever wonder what DEA do. So what exactly is an AED?

¿Qué representan sus siglas?

DEA stands for an Automatic External Defibrillator – don’t worry, it’s much easier to use than say.

¿Qué es un desfibrilador?

An Automatic External Defibrillator is a device that supplies a high-energy electric shock through the heart of a person experiencing sudden cardiac arrest. This electric shock is known as defibrillation and its goal is to return the heart to its normal rhythm.

¿Cómo funciona?

Defibrillators work very intuitively, which means that the person who uses it does not need to have specific training to save a life. They have vocal instructions, step by step, and usually include diagrams that guide you through the use process.

If you suspect that someone is suffering from cardiac arrest, you should call Emergencies immediately or, even better, get someone to call you while you manipulate the defibrillator. 

To begin the rescue, you must lift the lid or press the start button on your defibrillator. You will be instructed to place the electrodes on the patient’s bare skin, making sure that you place them in the right place. The images in the patches will tell you where to place them.

Next, the device will read and analyze the electrical activity of the heart. The AED automatically recognizes a rhythm that needs an electric shock. If you identify that you can help, you will be prompted to press the download button – even if you do not press anything on fully automatic DEA models. The electric shock can return the heart at its normal rate.

If the defibrillator indicates that “an electric shock is not needed,” continue with the CPR maneuver and continue with the subsequent instructions of the device until emergency services arrive.

¿Qué tipos de desfibrilador existen?

There are two main types of AED, semi-automatic and fully automatic.

A semi-automatic AED will instruct the user to provide an electric shock to a patient by pressing a button on the device. Alternatively, a fully automatic AED will supply the electric discharge automatically without any user intervention.

¿Cómo elegir un DEA?

In an emergency situation the most important factor is time – each second counts. In fact, when sudden cardiac arrest occurs, the chances of survival decrease by 10% for every minute that passes without defibrillation.

En los DEA semi-automáticos la persona realizando el rescate es quien está en control de pulsar el botón que suministra la descarga eléctrica a la víctima si se ha detectado un ritmo cardíaco que lo requiere. Esto puede ser deseable ya que permite a la persona que realiza el rescate asegurarse que no haya nadie en contacto con el cuerpo del paciente en el momento de administración la descarga, porque en efecto el DEA no es capaz de detectar si hay alguna otra persona tocando al paciente. El personal con formación médica suele preferir los DEA semi-automáticos. Posteriormente a la colocación de los parches y del análisis del corazón (garantizando que se ha detectado un ritmo cardíaco que requiere una descarga eléctrica), un DEA completamente automático administra la descarga al paciente sin intervención humana. La persona que realiza el rescate solo necesita asegurarse que no haya nadie tocando al paciente cuando se administra la desgarga.Fully automatic AEDs are often preferred in communities, schools, workplaces , etc.

If you are not sure if you need a semi-automatic or fully automatic AED, contact Cardiac Science for more information.

Sudden cardiac arrest is considered a medical emergency and requires immediate action, otherwise it can be fatal. In fact, heart disease (CVD) represents the leading cause of death in Spain, causing more than 125,000 deaths each year .

For these reasons, it is essential that in the case of an emergency, there is an AED at hand: this can mean the difference between life and death for a person. For this reason, at Cardiac Science we do everything we can to help people have an AED in their homes, schools, offices, shopping centers and much more.
