What is the correct way to use AED?
When using an AED, the first step is to turn on the machine. After the machine is turned on, the machine will issue the next instruction and complete it according to the operation instruction provided by the machine. Then choose the adult mode or the child mode according to the patient's age (use the child mode below 14). After selecting the mode, unbutton the clothes on the patient's chest according to the prompt, and stick the electrode sheet on the position of the patient's chest with corresponding pictures on it. Attach it and connect it to the AED. Do not touch the patient after connection. Click the shock button according to the prompt. Then the machine will prompt the patient to do artificial respiration and chest compressions.
How does AED work?
An evil arrhythmia in which the heart stops beating is called ventricular fibrillation. At this time, the heart is pounding. Simply put, there is no normal heartbeat. AED makes the electricity in the whole heart disappear to zero through the action of current, no matter whether it is good electrical activity or good electrical activity. In this case, the first reply is the sinus node of our normal human body. So once it recovers, it is a normal heartbeat. For example, our computer crashed and we can restart it. Pressing the restart button of the computer is like restarting our heart with a defibrillator, and then we can return to normal beating.
How was AED invented?
Cardiac defibrillation technology originated from 1947, and German Bauck invented external AC defibrillation technology. Then in 1952, Professor Paul Morris Zall successfully installed the world's first single-wave AC defibrillator. Later, it evolved into a common AED in our lives. AED is also called portable automated external defibrillator. At present, AEDs on the market can be divided into fully automatic and semi-automatic.
