As for college students whose cardiac arrest was saved by classmates' textbooks, as long as the method is correct, a person's life can be saved. Because in the case of sudden illness, the best treatment time is within one hour. If it exceeds this time period, it is easy to induce more diseases, so it is also good to learn some first aid methods appropriately.

Therefore, I have the following views to share with you:

First, the surrounding environment

When we encounter cardiac arrest, we should first pay attention to the surrounding environment. If there are many passers-by, we'd better keep a distance of one meter from them and keep the air circulating so that when we open the airway, the patient can feel it.

Second, artificial respiration.

When we give artificial respiration to a patient, we should first remove foreign bodies and vomit from the patient's mouth, then gently hold the patient's nose with our hands, take a deep breath, then put a piece of gauze on the other person's lips, cover his mouth with your mouth, gently blow, and then observe whether the patient's chest fluctuates, so as to achieve the therapeutic effect.

Third, news.

When we press the patient's chest, we should not only observe the patient's reaction, but also pay attention to our hand speed and whether the pressing position is accurate. When we press it, we'd better count to 00 1, 002,003 until 007, and then observe whether the other person's pulse is moving. If the other person's heart has recovered its function, then we don't need to continue pressing, but wait for the arrival of medical staff.

In addition, in the process of our first aid, we must keep a rational mind and must not panic, otherwise it is easy to make mistakes. Because life is not a trivial matter, once something goes wrong, it is likely to affect the other person's life, so don't treat it casually without being completely sure.
