At this time, some people will say, even if this machine is very simple and easy to learn, should it also popularize first aid knowledge to the public? Personally, I think this is a very necessary thing. We need to know where the vascular disease of the heart attacks faster, and then if there are professional medical staff or people who know professional first aid knowledge around us, it is likely to save people's lives within 4 minutes. At this time, it shows the importance of popularizing first aid knowledge to the public.
Each of us should master some first aid knowledge that can save others' lives. When we have seen the existence of aed in public and patients with cardiovascular and cerebrovascular diseases suddenly fall to the ground, as long as we have the relevant first aid knowledge and can use aed correctly, then we can become a superhero, a superhero who saves others' lives. Actually, being a superhero is not that complicated, as long as you can master some.
Personally, I think the times are developing and the society is progressing. With the gradual improvement of living standards, people's health is getting worse and worse, especially cardiovascular and cerebrovascular diseases have become invisible killers. Then we can save more lives by mastering some popular first aid knowledge.
