In fact, one of the FDA’s quality-assurance requirements is to review human factors testing to make sure that the defibrillator is easy to use. Each unit has voice instructions to help coach responders through the rescue process and AEDs are designed to be used by anyone with limited training. There are several models of FDA-approved AED units. So, if you are wondering why AEDs are used or what an AED is used for… The purpose of AEDs is to allow laypeople to save lives! Since AED machines are becoming increasingly present in public settings, especially where there is a lot of human traffic, AEDs can often be used immediately when a person goes into cardiac arrest instead of having to wait for the paramedics or police to administer the life-saving treatment. The AED performs the heart rhythm analysis for them. AED operators do not need to read and interpret a patient’s ECG which depicts the heart rhythm. AEDs are different because they are “automated” and completely take the guesswork out of determining whether or not someone needs a shock. If either of these rhythms are detected by the AED, the device delivers a controlled electric shock to the victim. Most people are familiar with in-hospital defibrillators or those used by emergency medical services that are part of advanced life support (ALS) units. The processor is used to analyze the patient’s rhythm to determine whether or not the patient is in a shockable rhythmĪEDs are capable of automatically detecting two forms of cardiac arrhythmias or irregular heart rhythms: ventricular fibrillation and pulseless ventricular tachycardia. Processor: The processor is the brains behind the AED.For AEDs, the capacitor has to be large enough to store enough energy, and then release it all at once, to save a patient’s life. Capacitors are very common electrical components and they come in different sizes or capacities. Capacitor: The capacitor stores and releases energy.The battery also plays an important role in running self-tests and AED diagnostics to make sure that the AED is functioning properly. Battery: The battery is used to charge the AED’s capacitor so that it has enough energy to deliver a life-saving shock.If a shock is determined to be necessary by the AED’s processor, then the shock travels between the pads and through the patient’s heart. The electrode pads are what reads the patient’s heart rhythm.
