In Qingdao's Line 1 subway, a man fainted in sudden cardiac arrest. The AED was used quickly by the subway staff, who gave the man CPR and artificial respiration according to the instructions on the device. Subway staff only took less than a minute to pull the man back from the hands of the grim reaper. AEDs are very important for people who suffer from cardiac arrest.
How to use an AED correctly?
The EDA, as a medical device that can cause electrocution, carries a certain level of risk, and should be operated in accordance with the requirements of the device. When using an AED, the machine will analyze the heart rhythm and assess the need for defibrillation as patches are applied to the rescued person based on verbal prompts. During this process, no one should touch the rescued person's body to avoid affecting the results of the analysis.Once the EDA has completed the first defibrillation, the user must immediately perform CPR. Users do not need to tear off the electrode pads of the AED when performing cardiac compressions, but only need to follow the voice of the AED to call 120 after the operation.
Where should AEDs be kept on hand?
I think that in addition to important public ****ing places such as stations, ports and airports, consideration should be given to placing some in sports venues and residential areas. From the current situation, most of the cardiac arrest time basically occurs in the sports ground. For example, in a foreign soccer match not long ago, a player suffered a cardiac arrest and collapsed during the match. It was the timely use of AED defibrillation by the first-aiders on the spot that could save the player's life. Therefore, I think stadiums, gymnasiums, swimming pools and other sports venues should be equipped with AEDs. in addition, most elderly people suffer from cardiovascular diseases. AEDs should also be available in residential areas and communities with a large number of elderly people.
How does an AED work?
In daily life and work, 80% of sudden cardiac arrests are caused by ventricular fibrillation. In the case of ventricular fibrillation, the heart muscle will experience rapid and weak contractions or rapid and uncoordinated fibrillation. As a result, the heart is unable to deliver blood, which is equivalent to a functioning engine, but unable to provide energy. This situation can easily lead to death.AED is lightweight and portable and can deliver shock defibrillation even after fibrillation. For this reason, it is known as a ? Life-saving talisman?
