Knowing when to use an AED: Guidelines for sudden cardiac arrest  

2-minute read

Sudden cardiac arrest is a life-threatening condition that can strike anyone, anywhere, at any time. When it occurs, every second counts, making it crucial to initiate prompt and effective life-saving measures. Cardiopulmonary resuscitation (CPR) combined with the use of an automated external defibrillator (AED) can significantly increase the chances of survival. In this article, we'll delve into the importance of knowing when to use an AED during a sudden cardiac arrest episode.

Understanding sudden cardiac arrest

Sudden cardiac arrest is distinct from a heart attack, though it can be triggered by one. A heart attack is caused by a blockage in a coronary artery, preventing blood flow to part of the heart muscle.¹ In contrast, cardiac arrest results from malfunctioning electrical impulses in the heart, causing it to suddenly stop beating effectively. When this happens, the individual will collapse without warning, lose consciousness, and will not have a discernible pulse.²

The crucial link in the chain of survival for someone experiencing sudden cardiac arrest is swift intervention. Every second matters. CPR is an important first aid technique whose primary goal is maintain circulatory flow and oxygenation to preserve vital organ function until further medical treatment is possible.³

Imagine the heart as a pump and the blood as the water it needs to circulate. If the pump stops, the water remains stagnant. CPR effectively acts as a manual pump, ensuring oxygenated blood keeps flowing to crucial organs, especially the brain.⁴ It's a stopgap measure until more advanced medical interventions, like the use of an AED, can be implemented.
