Automatic External Defibrillators or AEDs are life saving devices for when a patient suffers from a Sudden Cardiac Arrest (SCA).
SCA is often confused with a heart attack which is not the same. A heart attack occurs when the steady flow of blood to the heart is interrupted, usually by way of a blockage. This can then lead to SCA if not treated promptly.
A heart’s normal rhythm is known as Sinus rhythm which in adults is on average 60-100 beats per minute. During SCA, in the majority of cases, the heart enters what is known as Ventricular Fibrillation (VF). The is where the ventricles of the heart ‘quiver’ instead of pumping normally which is usually caused by irregular electrical activity.
An AED will analyse the patient’s heart and deliver a shock to help restore the heart to its normal rhythm.
AED training will help familiarise people in how an AED works and therefore act much more effectively in what is a very stressful, time-critical event.
