An automated external defibrillator (AED) is a laptop-sized device used for medical emergencies, specifically heart arrest or when the heart stops beating. Sometimes when a person is in cardiac arrest their heart starts to feel an abnormal quivering in the heart cells triggered by erratic electrical activity.Get More Info about AED.
This quivering is named, for example, ventricular fibrillation or V Fib. V Fib is administered with controlled electric shock to the neck. It happens when electric cells are found in the heart muscle. The AED is used to shock the heart at normal heart rhythm which is in V Fib.
Studies show that if an AED is used within 3-5 minutes of heart arrest, the chance of survival of the victim increases by about 70%. So as soon as it becomes available you want to use the AED.
Using the AED: At the vicitm’s hand once you get the AED-
1: Switch on the AED. Do this either by pressing the on / off button, or by lifting the unit lid.
2: Just follow the prompts as directed. The device will instruct you to put the electrode or pads into the victim’s bare skin. One of the pads is to be placed on the victim’s right upper chest, while the second pad is to be placed just below the left chest.
3: Once the pads have been put on the victim’s bare chest, you may need to install the pad adapter into the AED. These are already preconnected to some AED pads.
4: Next you have to make sure nobody (including yourself) touches the victim. The computer must request that it is “analyzing.” Both CPR attempts must be stopped during the review to enable the AED to determine whether the victim’s heart is having V Fib and can therefore be handled with a shock. This is one of the 2 occasions that you have to “clean” the person of any interaction with witnesses.
5: If the AED causes a shock to be registered, then a second time you will “clean” the patient, checking that you and no others are in contact with the victim. If someone approaches the patient while the AED provides the injection, then the bystander can also receive a shock that can even render them unconscious. You must then press the “shock” button to deliver a shock once you see that the victim is “clear” Fully automated AED’s immediately administer the pain.
6: The defibrillator will advise you to restart CPR soon after you have delivered the shock. You must not remove the pads at this time, or turn off the unit. Just leave the pads on the victim’s chest, leave the AED on and resume CPR starting with compressions to the chest.
Some of the latest AED versions have the CPR coaching feature that directs the rescuer through the CPR phase.
AEDs are very easy to use, as long as the instructions are fully followed. The information contained in this article does not replace a CPR / AED course in which all of the training is conducted. Such information is provided as a guide only for CPR / AED instruction supplements.
