Life-saving medical equipment

In the subway of Qingdao 1 Line, a man suddenly stopped and fainted to the ground. The nearby subway staff quickly used the AED and carried out a series of rescue measures such as cardiopulmonary resuscitation and artificial respiration on the man according to the tips on the equipment. It took the subway staff less than a minute to pull the man back from the hand of death. It can be seen that AED is very important for people with cardiac arrest.

How to use AED correctly?

EDA, as a kind of medical equipment that may cause electric shock, is dangerous and should be operated according to the requirements of the equipment. When using AED, the machine will analyze the heart rhythm and evaluate whether defibrillation is needed when sticking the patch to the rescued person according to the language prompt. In this process, no one is allowed to touch the body of the rescued person, so as not to affect the analysis results. After EDA completes the first defibrillation, the user must perform cardiopulmonary resuscitation immediately. Users don't need to tear off the electrode pads of the AED when performing cardiac compression, just dial 120 for rescue after the voice operation of the AED is finished.

Where should I put AEDs? ?

In my opinion, in addition to stations, ports, airports and other important public places, we should also consider placing some in sports venues and residential areas. Judging from the current situation, most of the time of cardiac arrest basically occurs in the sports field. For example, in a foreign football match not long ago, a player had a cardiac arrest and fainted during the game. It was the on-site emergency personnel who used AED to defibrillation in time and saved the lives of the players. Therefore, I think stadiums, gymnasiums, swimming pools and other sports venues should be equipped with AED. In addition, most elderly people suffer from cardiovascular diseases. Aeds should also be equipped in residential areas and communities with more elderly people.

What is the working principle of AED?

In daily life and work, 80% of cardiac arrest is caused by ventricular fibrillation. In the case of ventricular fibrillation, the myocardium will contract rapidly and weakly or vibrate rapidly and incongruously. So the heart can't deliver blood, which is equivalent to a running engine, but it can't provide energy. In this case, people can easily lead to death. AED is portable and easy to carry, and can be used for defibrillation even after heart fibrillation. Therefore, it is called. Life-saving artifact
