Defibrillator – Automated External Defibrillators



Defibrillation is a widely used treatment for many life-threatening heart related problems including: cardiac arrhythmias, ventricular fibrillation and ventricular tachycardia. A defibrillator is a device that delivers a therapeutic dose of electrical energy to the affected heart. The electrical current will treat many of the aforementioned conditions by depolarizing critical masses of the heart muscle, terminating the arrhythmia, or allowing normal sinus rhythm to be re-established by the human body’s own natural pacemaker, in the sinoatrial node of the heart. There are several different types of defibrillators, they can be external, transvenous, or implanted. Some external units, known as automated external defibrillators (AEDs), automate the diagnosis of treatable rhythms, meaning that pretty much anyone can use them with little, or no training at all.

Automated External Defibrillators

Automated External Defibrillators or (AED’s) are appearing in more and more locations with time. They have become standard fixtures in airports, schools, and other such locations that have or may have a large congregation of people or where emergency medical care and/or personnel is not readily available (e.g., on airplanes or cruise ships). AEDAED’s work by automatically detecting the abnormal arrhythmia or other life-threatening heart condition and will then only activate to deliver an electrical energy current if it detects it is needed in order to save the recipient’s life. Automatic External Defibrillators are simple enough that many of the available models can be used with little or no training at all. Since AEDs are designed to be simple to use, the use of Automated External Defibrillators is taught in many first aid, first responder and basic life support CPR classes.

Automated External Defibrillators Save Lives

There is no disputing the fact that AEDs actually save lives, study after study has shown that more people are surviving cardiac arrest thanks technological medical innovations like the Defibrillator. AEDs can be found in every major city in the world, many schools in the United States have them, they are becoming very common everywhere, yet the American Heart Association estimates that an additional 50,000 american lives could be saved every year if there was widespread availability of them. The fact that they are very effective and easy to deploy, it is no wonder that every day more and more locations obtain Defibrillators.
