The Automated External Defibrillator, or AED, is an emergency tool used to resuscitate patients whose hearts have stopped beating. The device sends an electric shock to the heart to make it contract, helping it to start beating in a regular rhythm again. AED and CPR are the most common first-aid options when a patient is unconscious and isn’t breathing. In this article, we’ll go into detail about AED, how it works, and how to use it in an emergency situation.
How does the AED system work?
Each AED unit comes with a heart rhythm analyzer, which will allow the user to see whether an electric charge is advised. The unit will examine the oxygen level and the electrical activity in the muscles of the heart. When the muscles aren’t supplied with enough oxygen, the heart often beats faster as a result, hoping to supply the organ with adequate oxygen-rich blood. Once the heart is unable to keep up with the workload, it will stop functioning. Additionally, irregularities in the heart rhythm can also cause the heart to stop beating abruptly. The AED analyzer can be placed on the patient to determine whether or not an electric shock is necessary.
There are two types of deadly heart rhythms that the unit will look for: ventricular fibrillation and ventricular tachycardia. If the analyzer detects one of these two conditions, it will allow a shock to be given. Once the shock is delivered, you will need to use the analyzer again to see if the heart has returned to its regular rhythm. It’s vital that you move quickly whenever you’re trying to perform a life-saving maneuver such as this. The longer the heart goes without oxygen, the more damage will be done and the lower the chances of resuscitation.
Importance considerations to keep in mind:
If the patient is in or near a water source such as a puddle or a pool, you will need to remove them from it and make sure that their body is as dry as possible. Moisture on the ground such as rain, snow, or wet soil is typically not a cause for concern. If the patient’s clothes are wet, you need to remove all of it, as the moisture can affect the delivery of the electric shock from the AED unit. If their clothes are dry, simply reveal the chest area of the patient, applying the pad right onto their body. Make sure that the pads come into contact with the bare skin of the patient.
Keep in mind that you are never to remove the AED pads from the patient or turn the machine off unless instructed by a professional.
How to use an AED machine
- Secure and dry the patient’s body. Turn on the machine and place one pad on the right side of the chest above the nipple. Then, place another pad on the patient’s lower ribs below the armpit. Secure the pad tightly onto the patient’s body.
- Once the pad is on, the AED unit will start the analysis. Do not touch the pad or move the patient during this time.
- If the AED says, “Shock advised, charging…,” shout, “Clear” and make sure no one is touching the patient. Push the shock button when the AED tells you to. If no shock is advised, give CPR if the patient is not moving and not breathing.
If a shock is required, the AED machine will say “Shock advised, charging…” During this process, you need to make sure that everyone is at least two feet away from the audience. Once the machine is ready for a shock, shout “Clear” loudly and clearly while you apply the electric charge.
- Once the shock is delivered, give 30 chest compressions followed immediately by 2 breaths down the throat. Continue the process until you see signs of life. The AED unit will automatically reanalyze the patient again in 2 minutes and advise you if a shock is required.
