An automated external defibrillator (AED) is a portable electronic device used to treat sudden cardiac arrest (SCA) by delivering an electric shock to the heart. AEDs are designed to be used by non-medical personnel in emergency situations, making them an essential tool in any workplace or public setting. In this article, we will discuss the importance of AEDs and how they work.
Importance of AEDs
SCA is a leading cause of death worldwide. It occurs when the heart's electrical system malfunctions, causing the heart to stop beating. SCA can happen to anyone, anywhere, at any time, and immediate treatment is crucial for survival. AEDs can increase the chances of survival by up to 75%, making them a critical tool for responding to SCA.
How AEDs Work
AEDs are designed to be easy to use, even for people without medical training. The device analyzes the heart's rhythm and delivers an electric shock if necessary. Here's how AEDs work:
Step 1: Turn on the AED
Press the on/off button to turn on the AED. The device will provide voice and visual prompts to guide you through the process.
Step 2: Attach the Pads
Attach the pads to the person's bare chest. The pads have adhesive on the back and are marked with pictures to show where to place them.
Step 3: Analyze the Heart's Rhythm
Press the analyze button to allow the AED to analyze the person's heart rhythm. The device will analyze the rhythm and determine if a shock is necessary.
Step 4: Deliver the Shock
If the AED determines a shock is necessary, it will prompt you to press the shock button. Make sure no one is touching the person or the pads before delivering the shock.
Step 5: Begin CPR
After delivering the shock, begin CPR. The AED will provide voice prompts to guide you through the process of CPR.
Step 6: Repeat as Necessary and leave the pads on! Even if the individual's heart suddenly starts beating! If the heart is still stressed, it may go back in cardiac arrest heart and now you've wasted time needing to put the pads back on!!! Keep them on until EMS arrives!
Continue to use the AED and perform CPR as necessary until medical help arrives.
In conclusion, AEDs are a vital tool in responding to sudden cardiac arrest. They are easy to use and can significantly increase the chances of survival. Knowing how to use an AED can make the difference between life and death in an emergency situation. It is important to have AEDs readily available in workplaces and public areas and to ensure that individuals are trained in their use.
