The heart operates through electrical signals that alert it to pump blood. The electrical signal results in the ventricles contracting to squeeze blood out of the heart. After each contraction follows a relaxation whereby blood flows into the heart. When the heart is ailing from an injury or disease, its electrical activity is likely to disrupt. In the event, the circulation of blood through the body is insufficient. In most instances, the ventricles fibrillate or quiver in what is known as ventricle fibrillation (V-fib). The second instance is when the ventricles contract faster than usual, and it is known as ventricular tachycardia (V-tach)
The result of these is sudden cardiac arrest. The electric signals occur randomly, resulting in chaos within the heart. The limited supply of oxygen within the body causes the individual to collapse and stop breathing.
V-tach and V-fib are, in most cases, rectifiable through electrical shock delivered by AED. The AED analyses the state of the heart and delivers an electrical shock (defibrillation). The shock enables the heart to restore its rhythm. Every minute delayed before CPR, and AED reduces the chances of survival by 10%. Therefore, everyone must learn skills in performing CPR and how to use the AED.
Information on the use of the AED is essential as you never know the person you’ll use the skills on. Online CPR/AED certification courses are available at your convenience with no limitations and can be taken anywhere at any time. All required to take up the CPR/AED classes is your computer and internet connection.
