An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
An external, wearable cardioverter-defibrillator with defibrillation features similar to an ICD could be a solution to be used as “bridge” to protect these patients from SCD. In 1986, M. Stephen Heilman and Larry Bowling founded LIFECOR and started the development of the first wearable cardioverter defibrillator (WCD). It was named LifeVest®.
A defibrillation device that is often available outside of medical centers is the automated external defibrillator (AED), [8] a portable machine that can be used with no previous training. That is possible because the machine produces pre-recorded voice instructions that guide the user.
Defibrillation. Defibrillation: position of the electrodes of a defibrillator on the human body. The standard defibrillation device, prepared for a fast use out of the medical centres, is the automated external defibrillator (AED), a portable machine of small size (similar to a briefcase) that can be used by any user with no previous training.
In 1972 Bernard Lown, the inventor of the external defibrillator, and Paul Axelrod stated in the journal Circulation – "The very rare patient who has frequent bouts of ventricular fibrillation is best treated in a coronary care unit and is better served by an effective anti-arrhythmic program or surgical correction of inadequate coronary ...
Once an automated external defibrillator (AED) has been acquired the rescuer should then finish the round of CPR, use the AED and then begin another round of CPR. However the AED will usually notify the rescuer of any impediments to continued CPR (such as a sinus rhythm or asystole) in which case the rescuer may be prompted to cease CPR.
In out-of-hospital arrests (OHA), the defibrillation is made by an automated external defibrillator (AED), a portable machine that can be used by any user. The AED provides voice instructions that guide the process, automatically checks the person's condition, and applies the appropriate electric shocks.
Lightweight portable Automated External Defibrillators (AED) are mandated by federal and state authorities in many locations, including schools, commercial airplanes, airports, and health clubs. Since 2005, there have now wearable automatic defibrillators that need no direct medical interventions.
