At the start, I tricked the school beauty, and ended up with twins?

Having carefully removed the shards of glass from the unconscious student's neck, Dai Zhengguo immediately saw the bleeding wound.

Besides the injured carotid artery, there were minor scratches and puncture wounds on various parts of the body.

But none were serious; the most severe was the cut to the carotid artery.

"Carotid artery cut, but thankfully, the wound isn't large!"

Although the carotid artery bled quickly due to high pressure, the wound was still within controllable limits. Had the artery been completely severed, not even Hua Tuo, were he alive, could have saved him!

He selectively ignored the other wounds.

From the pocket of his coat, he took out a red mini first-aid kit.

He first meticulously cleaned his hands with a portable medical alcohol wipe, then took out a sterilized gauze, reached down to the pulsation point of the artery, and found the spot 1-2 cm from the proximal end, where Dai Zhengguo immediately began to treat the bleeding!

Deserving of his position as a director-level physician, his motions were very proficient, and he completed the emergency treatment of the wound in less than a minute.

His fingers never let go from the beginning to the end, maintaining appropriate pressure on the bandage to prevent major bleeding from the wound.

All that was needed now was to patiently wait for the emergency responders to arrive and take him to the hospital.

Dai Zhengguo breathed a sigh of relief.

Luckily, he had decided on a whim to change things up and eat at the farther B2 cafeteria today, otherwise this student might have been out of luck!

Bleeding from the carotid artery can indeed be fatal!

"Mr. Dai is so handsome! A true man-god!"

"Professor Dai did great!"

"I'll never goof off in lab class again!"

"I really want to study medicine!"

"..."

The surrounding students spontaneously applauded, expressing their admiration for Teacher Dai Zhengguo.

Mixed among them, several medical students appeared particularly proud, as Mr. Dai was their direct teacher!

In the future, they were very likely to pursue their Master's degrees under Dai Zhengguo!

"Mr. Dai! Please release your fingers quickly!"

Just as everyone was full of praise, a discordant voice suddenly sounded from the left side of the crowd.

All eyes were drawn to the voice, looking towards the left.

Three male and three female students, including school beauty Lin Xiaohua, were present!

Initially seeing the three male students running with stools, everyone guessed they must be roommates related to the victim.

All eyes puzzledly looked their way, but Gu Yu remained unmoved.

Still shouting towards Dai Zhengguo, he said:

"Mr. Dai, please release your fingers quickly! I suspect my roommate not only has a severed carotid artery, but also has tension pneumothorax!"

"You pressing your fingers on his neck affects his breathing, which can lead to a rapid increase in thoracic pressure, ultimately causing severe lung compression!"

Gu Yu said all this in one breath.

The people around were dumbstruck, most of them did not understand, but they could see the implications.

Immediately, whispers spread through the crowd, and everyone glanced at Gu Yu with a peculiar look.

"Is this student suggesting that Professor Dai's treatment is incorrect?"

"Is he a student from the Medical College? He doesn't seem to be."

"We are clinical medicine students, and we've never seen this fellow! Is he crazy? Is he teaching Mr. Dai how to do his job?"

"Outsiders enjoy the spectacle, insiders see the joke! Is he joking with his roommate's life?"

"..."

The whispers grew louder, everyone subtly pointing and whispering about Gu Yu.

Even Dai Zhengguo frowned, a student, obviously not from the medical field, questioning him was a direct challenge to his authority.

A spark of anger flared in his heart.

But he was also a professor, having taught countless students, and had seen all kinds of situations.

Technically, he could have chosen to simply ignore this meddlesome student.

But, committed to the spirit of imparting knowledge and solving doubts, he still asked a question.

"This student, I see you are probably not from our Medical College, are you? So, you should not have been exposed to professional medical knowledge; how did you diagnose your roommate with tension pneumothorax?"

The so-called pneumothorax, as the name suggests, is when gas enters the pleural cavity between the lungs and the chest wall.

Normally, there is no gas in the pleural cavity, maintaining a negative pressure to allow the lungs to expand and contract with the movements of the chest wall.

There are three common types of pneumothorax: tension, closed, and open.

The tension pneumothorax Gu Yu mentioned is caused by external gas continuously entering the pleural cavity, entering but not exiting, leading to an increase in pressure within the cavity, consequently compressing the lung.

This can cause difficulty in breathing and, in severe cases, lead to death.

"Because I am quite far, I also am not absolutely sure of my speculation, so Mr. Dai, could you please now check my roommate's left arm?"

"If I observed correctly, there should be signs of venous dilatation, right? The cause should be regional blood blockage?"

"Also, there's a wound on my roommate's chest bleeding outward, I don't know if you noticed, but his chest wall also seems a bit larger than normal?"

Gu Yu quickly stated the basis for his speculation.

At that moment, his brain worked like a precise computer, rapidly deconstructing the bodily structure of the injured Boss Pu's wounds.

Veins that were invisible to others were clearly visible in Gu Yu's eyes.

This was not to say he had x-ray vision, but rather a combination of knowledge and deconstruction thinking forming a mental image, or imagination.

After listening to Gu Yu's explanation, Dai Zhengguo was surprised to find that this "layman" student's words were quite professional.

So, he followed Gu Yu's instructions and gently pulled up the injured student's left sleeve, and sure enough, he saw the phenomenon of venous dilation!

And it was very obvious!

Dai Zhengguo's heart couldn't help but skip a beat.

"Could it be that what this student said is true?" he muttered.

He tentatively released the fingers pressing on the victim's neck!

Sure enough, the victim slightly opened his mouth and started breathing, but it was clearly less inhalation and more exhalation!

These were symptoms of the lungs being compressed!

Dai Zhengguo could not help but feel somewhat panicked.

He hurriedly tore open the victim's jacket and carefully lifted the blood-stained undershirt, and Dai Zhengguo was shocked!

A long, prism-shaped piece of glass was embedded in the left intercostal space of the victim!

With each contracting movement at the wound, a small amount of blood was even being sucked back into the entrance!

"Collapse of the lateral pulmonary structure! Tension pneumothorax!" he exclaimed.

Relying on his extensive experience, Dai Zhengguo immediately diagnosed the injury!

It was exactly as the student had guessed!

But now was not the time for him to dwell on whether Gu Yu was right or not!

This was a life-threatening, critical condition!

Tension pneumothorax required immediate decompression by puncture!

But he did not have surgical tools on hand, nor could he perform an on-site surgery like in the movies where doctors save people at airports!

Open-air surgery? That would be gambling with a life!

Just as Dai Zhengguo was uncertain what to do, the medical office's doctor finally arrived!

"Director Dai, what's the situation?"

A thirty-year-old female doctor carrying a medical kit ran to the front, the nurses carrying the stretcher couldn't even catch up.

"Has the medical vehicle arrived?" Dai Zhengguo asked without answering.

The female doctor was startled for a moment, then quickly nodded her head.

"Go! We must go immediately! We can't take him to the campus medical station! Send him directly to the Affiliated Hospital for emergency care!"

"What!?"

The female doctor was stunned, realizing the severity of the situation!

She quickly signaled the male nurse behind her to lift the injured student onto the medical vehicle.

As the first responder on the scene, Dai Zhengguo naturally had to follow along to the Affiliated Hospital.

As he passed by Gu Yu, he suddenly thought of something and casually asked, "Would you like to come along?"

"Ah?" Gu Yu hadn't expected Dai Zhengguo to directly invite him to the hospital.

"I think your roommate needs someone to take care of him," Dai Zhengguo added.

Gu Yu came back to his senses and quickly nodded, following Dai Zhengguo onto the medical vehicle.

Just before closing the door, Gu Yu hastily called out to Yu and Qin.

"Yu, Qin! Keep an eye on that woman! Don't let her get away!"

"Don't worry! We'll definitely keep an eye on her!" Yu Shutong and Qin Shan immediately responded.

Joking! That was the perpetrator who hurt the brother!

Everyone could run! She couldn't!

Gu Yu then closed the door of the vehicle with peace of mind.

Watching the medical vehicle speed away, the students in the cafeteria were all abuzz!

Professor Dai had actually misdiagnosed!

The key was that he was corrected by a student not majoring in medicine!

"Damn! Am I studying fake medicine?"

"Mom! I want to drop out! I studied medicine for nothing!"

Some medical students were so frustrated that they stomped their feet.

Others began to seek out information.

"Who is that student? He seems to be with the school beauty, Lin Xiaohua?"

"Seems to be Gu Yu from Software and Big Data College, software engineering class 1? Senior, class of 18!"

"Damn! That Gu Yu, why does that name sound so familiar?"

"Isn't he also the one on that weird notice posted under the dorm building?"

"Class of '18, software engineering 1! Definitely! Amazing! Gu 'O'neil' Yu is also Haimor 'Shawn'!"

In no time, the news changed rapidly, and Gu Yu's name, starting from cafeteria B2, quickly spread throughout Haidong University!
