For example, when performing chest compressions, the base of the left palm is placed on the lower sternum in front of the patient's chest, the right palm is pressed against the back of the left hand, and the fingers of both hands are raised without touching the patient's chest wall.

Moreover, even the arms, the elbow joints are not bent, and the shoulders are used to create pressure downwards and press the sternum down how much.

Among them, the number of adults and the number of children were all told to him one by one.

In addition to these, Ye Tingcheng also told him some precautions about CPR.

The patient should be asked to tilt his head so that the cavity and throat are in a straight line to prevent the tongue from blocking the airway opening and keep the airway open.

It is also necessary to blow not too much and not for too long, so as to avoid other acute gastric dilation, and also pay attention to whether the patient's airway is unobstructed and whether the chest cavity is blown up.

Furthermore, the pressure site should not be too low, so as not to damage the liver, stomach and other internal organs.

The pressure should be appropriate, if it is light, it is not enough to promote blood circulation, and if it is heavy, it will cause sternal fractures and bring pneumothorax hemothorax accidents.

"Anything else?"

Dr. Wu looked at her blankly, hoping that she would say more.

"Nope." Ye Tingcheng shook his head and said to Dr. Wu, who wanted to hear more: "I am not a professional doctor after all, and I have happened to meet and see someone saving people like this."

If it weren't for the urgency of the situation today, I wouldn't have rushed forward to save the tiger's head. ”

If she hadn't had confidence in herself, she would have told Dr. Wu about CPR first, and he would treat the tiger head.

"That's right." Although Dr. Wu was a little disappointed, he nodded yes.

Immediately, he carefully put away the small notebook, and the careful look seemed as if what he had put away was not a small notebook, but a priceless treasure that was hard to find.

"You're right, I forced it. In fact, being able to hear this and see you saving people is enough to benefit me for the rest of my life. ”

As he spoke, he solemnly bowed to Ye Tingcheng: "Thank you, you don't hide your selfishness today, and you give you everything." ”

"Doctor Wu, you are serious. It was your benevolence and medical virtue that made me not have the slightest reservation. ”

Ye Chengcheng hurriedly flashed to the side, not letting Doctor Wu give him this big gift: "If it were a different person, I might never say these words." ”

She admired Dr. Wu for having a benevolent heart, so she did not refuse his request.

Moreover, it was the people of Xiaoqing Village who gave her confidence and made her believe that people's hearts were not all evil like the scum of the Ye family, so that she could tell Dr. Wu everything.

Seeing that she woke up the tiger head, those worried onlookers did not suspect her because of this, nor did they come up to her and question her, how could you have such insight as a village girl.

It can be said that Xiaoqingcun accepted her, and she let go of her heart.

"So, do you want to study medicine?"

Dr. Wu saw the scene of her saving the tiger's head with her own eyes, and when she heard her say that she was not a professional doctor, she couldn't help but ask more.

I didn't think she couldn't practice medicine because she was a woman or a village girl.

"Me, is that okay?" Ye Tingcheng pointed at himself and asked rhetorically with not very confidence.

"Yes, of course. Just because you have a heart to save people, you are qualified to study medicine. Dr. Wu nodded vigorously, quite agreeing with her.

"Then, Doctor Wu, do you have time to teach me?"

Since Dr. Wu said so, Ye Tingcheng felt that he didn't bother the two masters, so he simply asked Dr. Wu to teach her.

She wondered, if she could learn medical skills with her abilities, would she be more confident in treating Ling and Ling Xiao.

"Are you literate?" Dr. Wu agreed, and suddenly thought of this and asked.

"Literacy was secretly learned from an old woman in the village."

This Ye Chengcheng didn't lie, the scum of the Ye family didn't treat her predecessor as a person, as a daughter, and she was a girl, so naturally she wouldn't let her go to study and write.

In their hearts, a cow and horse only need to work, and reading or writing is simply a dream, even if she is a cow and horse!

The predecessor was a housemaid, but she was not locked up in the Ye family's yard every day, and there was always a time to go out.

It was also at that time that the predecessor met an old woman who had been outside for decades and was alone when she came back.

She helped the old woman do a lot of things, and after the old woman asked her, she asked her to read and write.

This is a secret that belongs only to the predecessor, until the predecessor was forced to death by the Ye family scumbag, the Ye family scum didn't know her secret.

For this reason, Ye Chengcheng is very grateful to his predecessor and the old woman who taught her predecessor to read and write.

In this way, she doesn't have to find any other excuse to tell Dr. Wu that she is literate.

As for why the old woman was so knowledgeable, Ye Qingcheng was not curious.

Besides, the old woman is already in the past, which is one of the reasons why the predecessor is becoming more and more autistic and cowardly.

"Then I'll get you a few medical books first, and you can take a look." Dr. Wu thought for a while and said, "If you don't understand, just ask me." ”

"Okay, that's right, Dr. Wu." Ye Qingcheng nodded, and suddenly thought of one thing.

"What's the matter, you say." Dr. Wu looked at her with a smile, genuinely happy that she could study medicine.

"Doctor Wu, although the tiger head has woken up from falling into the water, will you prescribe another dose of calming decoction for him?"

Ye Qingcheng suddenly thought of this, after all, the tiger head was frightened, if he didn't drink another decoction.

It is very likely that you will suddenly be frightened at night and cry and can't sleep.

"Open, I'll open it." Dr. Wu just picked up the pen to write, but stopped again: "You will ask, is there a prescription?" ”

"Doctor Wu, I remember a prescription, but I don't know if I can use it?"

Ye Chengcheng took the pen and paper he handed over, wrote down a prescription for soothing the nerves, and then said: "My name is Ye Tingcheng, Doctor Wu, you can call me Chengcheng directly." ”

According to her observations, in this time and space, village girls like her do not have the kind of rules that cannot tell others, especially men's names.

Therefore, there is no need for her to scruple about not telling Dr. Wu her name.

"Okay, Allure, did you write down this prescription after you heard it?"

Dr. Wu took the prescription she had written, only glanced at it, and his eyes lit up again, and it could be seen that he admired this prescription very much.

"Yes, that's what I've heard before." Ye Chengcheng wasn't doubting Dr. Wu's medical skills, he just thought that if Dr. Wu didn't know this prescription, she could be regarded as a little help.

"Just follow the prescription you wrote!" As soon as Dr. Wu made the final decision, he immediately opened the medicine box on his back and carefully grabbed the medicine according to the prescription.

His movements are fast, and he doesn't need to weigh them, he just relies on his feel to grasp the medicine.
