After walking only a few hundred meters to the school, there are a few big characters written on the door of Taiqing Medical College.

Because it was a weekend, the school gate was open, and many students came and went, so Guo Xiang did not attract attention when he entered.

The school doesn't seem to be very big, a bit shabby, and you can see several teaching buildings when you enter the door, and there is a woodcut campus map in front of the building.

Guo Xiang took a look at the location of the east building of the girls' dormitory and turned to the left.

Passing by a playground, there were a few boys playing basketball, and some students were sitting under the trees on the side of the track.

Suddenly, someone screamed, and several students gathered around.

"What to do? Do you want to call a school doctor? ”

"Report to the teacher......"

"Just send it to the hospital!"

"But you can't move, can you? What if something happens......"

Guo Xiang heard the voice and hurriedly ran over.

Pulling away from the crowd, I saw a girl lying on the ground with a pale face.

"What's going on?" Guo Xiang asked.

Several people looked at Guo Xiang and saw that she was dressed not like a student, but she was too young to say that she was a teacher, who was she?

"Speak!" Guo Xiang put the bag at his feet and squatted down to look at the girl.

"We made a bet and she lost, and she was penalized for running three thousand meters......," one girl muttered.

Three thousand meters? Guo Xiang rolled his eyes, the physical strength of ordinary girls is not so good, and it is still such a hot day.

"Did you get heat stroke?"

"You're exhausted, aren't you?"

Several classmates speculated.

As soon as Guo Xiang touched the girl's hand, his body was cold, it was not heat stroke at all, if he had heat stroke, he had a high fever.

And this girl has cold limbs, her forehead is full of cold sweat, she feels her pulse, she is weak, her heart rate slows down, her breathing is very slow, she opens her eyelids and looks, her pupils are narrow, she is slow to respond to the light reflex, and she is already in shock.

"It's exercise shock!" At this time, a slender boy walked over.

He raised the girl's lower limbs and shook them gently, and then went to pinch the girl's middle again.

Renzhong is the depression under the nose, which is called Renzhong acupoint in traditional Chinese medicine, but in Western medicine, stimulating human middle is equivalent to adrenaline, which also has a first-aid effect.

But after some tossing, the girl didn't wake up.

The boy was also a little panicked, "Let's go call the school doctor!" ”

"But there's no one on vacation today, right?"

"I'm coming!" Guo Xiang said that the reason why he didn't push the boy away was because he did the right thing, and if it was her, she would do it herself.

But if that doesn't work, there's another way.

Guo Xiang took off the girl's shoes and socks, and pinched the tendons of the girl's heel with his nails, but the girl still didn't wake up.

Guo Xiang took out a handkerchief, put it on the girl's heel, picked it up and put it in his mouth and bit it.

"Huh? What is she doing? ”

"I don't know......"

"Isn't it dirty?"

The boy who gave first aid to the girl before also looked at Guo Xiang in surprise, not knowing what she was doing.

Guo Xiang bit one foot, changed to the other, and bit down hard at the tendon.

The girl suddenly "snorted" and woke up.

"Wake up, wake up, great!"

"What is this method, and why is it so magical?"

"What's the principle?"

When the girl opened her eyes, she was still a little confused when she saw so many people surrounding her, and she didn't know what was going on.

Guo Xiang raised her feet slightly higher and said to the girl: "You were unconscious just now, don't move yet, lie down and rest for a while, and then get up when you are better." ”

The girl shook her head and was really dizzy, and she didn't dare to move again.

"Whoever is going to get some water, preferably lukewarm." Guo Xiang said.

"I'll go right away." The girl who said she was betting before said and ran out.

After a while, the water came, Guo Xiang helped the girl up, fed her some water, and the girl slowly eased up.

"What's going on?" The boy just now looked at Guo Xiang curiously.

"What you just said about sports shock is right, to be precise, it should be called 'gravitational shock'." Guo Xiang said: "She should have stopped suddenly after a strenuous long-distance run, her blood pressure dropped sharply, her heart beat faster, and the concentration of norepinephrine in her blood was 10 times that of normal and 3 times that of normal. ”

"Originally, the rapid heartbeat and increased norepinephrine and adrenaline were reflexively released by the body to restore blood pressure, but the stress hormone was too large, causing arrhythmia and shock."

"So, you must not stop immediately after your run, but walk slowly, transition and stop. Otherwise, it may not be as simple as shock, and sudden death may occur. ”

"Then what was the principle of you biting her heel just now?" The boy asked again.

Guo Xiang smiled, "This is first aid from a reflex perspective, because the receptors on the triceps tendon of the calf are stimulated with sufficient strength to cause nerve impulses, and the nerve impulses are transmitted to the center along a certain sensory pathway, until the brain, so that the patient can quickly regain consciousness." ”

"I see!"

Several people looked at Guo Xiang with admiration, curious about who she was.

"Go back and get some rest!" Guo Xiang said to the girl, picked up his bag and stood up, and walked out of the playground.

"Thank you!" A girl's faint voice came from behind.

"Who the hell is she?" Someone asked.

"I don't know!"

"Is it a teacher? Why haven't I seen it, is it new? ”

"Impossible, you're still so young, isn't it a senior sister?"

"No, why haven't I seen such a beautiful senior sister?"

The boy looked at Guo Xiang's distant back, and his face was also full of doubts.

Guo Xiang approached the girls' dormitory area, found the east building, and was about to walk in, when a girl suddenly rushed out of the corridor, Guo Xiang couldn't dodge, and the two collided together.

"Ouch!" The girl screamed, covered her head with her hands and looked at Guo Xiang angrily, "What's the matter with you?" You don't have long eyes when you walk! ”

Guo Xiang frowned, "You bumped into it yourself, do you blame me?" ”

"If it weren't for you here, I could have bumped into it, and you wouldn't have dodged a point?" That girl was not reasonable at all.

"The road is so wide, you won't go to the side, who are you going to blame for bumping into it?" Guo Xiang sneered.

"You ......" The girl's face was ugly when she saw Guo Xiang being so tough, "Forget it, I still have something to do, don't let me run into you next time......"

What about running into me? Guo Xiang looked at her coldly, do you still want to beat me? Try!

The girl seemed to be in a hurry and ran away, Guo Xiang went upstairs to find room 302.

Walking to the door of the dormitory, the door was not closed, Guo Xiang knocked on the door and walked out.

Several girls in the dormitory were there, and they saw Guo Xiang looking at her in surprise.

"Hello, I'm Guo Xiang!" Guo Xiang smiled and greeted a few people.

"You are Guo Xiang? You're finally here? A girl on the top bunk said.

"Hmm!" Guo Xiang smiled, walked in, saw that there was a vacant shop that should be his own, and walked over.

It's still a lower bunk, and no one robs it, it seems that these girls are quite conscious.

"You came just after the military training, it's really time to get sick!" Someone mocked.
