AED stands for automated external defibrillator, also known as automated external defibrillator, and is a portable medical device.
It can diagnose specific cardiac arrhythmias and give defibrillation; it is a medical device used by non-specialists to resuscitate patients who have suffered sudden cardiac death. Sudden cardiac arrest can occur at any time, in any place, and waiting for medical personnel to arrive on the scene can result in missing the optimal time for resuscitation.The use of an AED buys time and provides the opportunity to save the patient in time.
The AED is an automated external defibrillator, commonly used in patients who experience ventricular fibrillation, and is a medical device that uses the act of delivering an electric shock to restore the heart to a normal rate of beat.The AED has a built-in analyzer that automatically detects the heart rate of a person who has suffered a cardiac arrest. If it is a defibrillatable rhythm, the AED will automatically recharge and deliver a shock, terminating the lethal rhythm and giving the heart a chance to return to a normal beat. (Note: Fully automatic AEDs are automatically shocked, while semi-automatic AEDs require the shock button to be pressed manually.)
Precautions for using AED:
1. If the patient is in the water, pull him/her out of the water; if his/her chest is covered with water, or if he/she is lying on snow or in a small puddle of water, quickly wipe his/her chest and then attach the electrode pads.
2. If there is hair on the patient's chest, which may prevent the electrode pads from sticking to the skin, you can use the razor in the AED's carrying case to shave off the hair on the area where the electrode pads are placed.
3. If you find a hard lump under the skin of the patient's upper chest or abdomen that is about half the size of a piece of cardboard, it may be an implantable defibrillator/pacemaker, so avoid placing the AED electrode pads directly on the implanted device. Do not place the electrode pads on the medication patches either; the patches may prevent the transfer of energy from the electrode pads to the heart and may also cause minor burns to the skin.
