AED Unit Automated External Defibrillator
What is an AED?
An AED (Automated External Defibrillator) is a sophisticated, battery powered microprocessor based device that encorporates a heart rhythm analysis and shock advisory system. The portable versions are designed to be used by lay rescuers although the use of a defibrillator may be restricted to professional medical technicians in some areas. The Defibrillator connects to the patient by two chest pads which then automatically analyses whether a shock is required or not. The electric shock that is sent through the heart by the defibrillator is capable of interrupting the abnormal twitching of a heart during SCA (sudden cardiac arrest) and may restore normal cardiac rhythms. Using an AED machine requires additional tuition by a trained professional and the information above is meant only as a general guideline for Automated External Defibrillators.
How does an AED save a life?
Recent research indicates that lay rescuer CPR and AED use, have doubled the survival rate of sudden cardiac arrest, compared to early EMS call and early CPR alone. The studies showed that layperson rescuers who are trained in the usage of CPR and Automated External Defibrillators using a planned and practical response including activating the local EMS system, significantly increase the survival rate of sudden cardiac arrest patients. Because early defibrillation is so important, many businesses, government agencies, and other institutions have AED units readily available in buildings, recreational facilities and other places for public accessibility.
What are the general features of AED's?
Although AED models look slightly different, the principles for using them are the same.The main differences include the screen displays, verbal prompts, documentation and how the device analyzes the cardiac rhythm. Regardless of its specific features, once an AED determines that the rhythm is shockable and the device charges up, it will prompt you to deliver the electric shock to the patient.
