Chapter 1453 Killing Technique

Zheng Ren raised his head, the color of the waiter's system panel quickly turned red from light green, and a diagnosis appeared in front of Zheng Ren - tension pneumothorax.

This is a fatal disease.

Tension pneumothorax refers to the rupture of a larger pulmonary air bubble or a larger and deeper laceration of the lung or the rupture of the bronchus, and the laceration communicates with the pleural cavity and forms a one-way valve.

When inhaling, the air enters the pleural cavity from the crack, and when exhaling, the valve closes, and the air in the cavity cannot be discharged, causing the pressure in the pleural cavity to rise continuously, compressing the lung and causing it to collapse gradually.

If the high-pressure air in the pleural cavity is squeezed into the mediastinum, it spreads to the subcutaneous tissue, resulting in subcutaneous emphysema in the neck, face, chest, etc.

The onset of this disease is rapid, and if it is delayed for a period of time, it is very likely to be fatal.

The waiter was as tall and thin as a bamboo pole.

A boy of this stature is the most prone to spontaneous pneumothorax.

Zheng Ren stood up suddenly, let go of Xie Yiren's hand, and strode to the waiter's side.

"Are you uncomfortable?" Zheng Ren asked gently.

Switch from diner mode to doctor mode, and prepare for emergency rescue without any obstacles.

The waiter was very young and looked less than 20 years old. He was sweating all over, and his face was flushed red.

But in just a moment, the blood on his face receded like a tide, followed by a pale white.

He nodded, wanting to smile to signal that he was okay.

But there was a sharp pain in his chest before, and now he started to feel tight in his chest, and he began to breathe rapidly.

Zheng Ren knew that this was the body's natural reaction.

In a state of hypoxia, it is natural to inhale hard, just like in a plateau area at an altitude of 4,000 meters.

But the more you inhale, the more air is trapped in the chest cavity, and the faster the lung tissue compresses.

Lung tissue is rapidly squashed, resulting in increased dyspnea, and the patient continues to struggle to breathe.

This is a process of negative feedback, and it is also the reason why patients with tension pneumothorax have an acute onset and a high risk of death.

"Don't worry, you sit down." Zheng Ren supported the young man's arm, supported the strength of his body, and helped him to sit down on a chair next to him.

"What are you doing!" The person sitting there was also holding a wine bottle, and it seemed that he was drunk, with an unhappy expression on his face, completely unaware of the situation.

"Please let me go, he is ill." Zheng Ren said.

"Why! I'm here to consume." The man roared with wide eyes.

Su Yun came over with a chair, and with Zheng Ren, helped the waiter to sit down, ignoring the middle-aged man next to him.

There's no point in arguing at this point.

Besides, they were right, he was here to eat, not a doctor, so he didn't know what happened.

Even a doctor, except for Zheng Ren's coercion, no one knows what happened.

Helping the waiter to sit down, Zheng Ren tore off his shirt and put his ear to it.

"Spontaneous pneumothorax?" Lao He stood up and asked with some doubts.

"Maybe, the boss is doing a physical examination." Su Yun then turned around and asked, "Xiao Feng, do you have a stethoscope?"

Feng Xuhui was dumbfounded.

Although the box is big, it is all intervention consumables. Who needs a first aid kit when going out?

Besides, given the scope of Boss Zheng's surgery, a first aid kit alone might not be enough.

Su Yun was also very sorry. He saw Zheng Ren raised his head and began to percussion.

The left hand was placed on the chest wall of the attendant, and the middle finger of the right hand tapped the middle finger joint of the left hand, shocking the patient's chest wall, and there was a sound of percussion.

The sound was not too loud, but Su Yun heard something unusual.

For the most basic thoracic surgery examination, if he can't hear it, he can wash and sleep.

Lao He also heard something unusual, and said in surprise, "It's really pneumothorax."

With that, he took out his mobile phone and started dialing 120.

"Lao He, it's better to call 120 with a chest bottle." Zheng Ren said solemnly.

"Tension pneumothorax?!" Su Yun asked.

Zheng Ren nodded.

The diners around looked at what was happening on this side and talked a lot.

"What happened to that waiter?"

"I don't know, tsk tsk, the clothes are torn. That young man still has this hobby? This is harassment. It's indecent in broad daylight."

"Why didn't that person fight back? The waiter can't be bullied, it's just too much!"

Several diners with a sense of justice stood up and denounced Zheng Ren one after another.

The boss also came out and asked with a puzzled look: "What's the matter?"

"He suddenly had a pneumothorax...he was very ill, and the 120 ambulance was called." Zheng Ren said, "Do you have a syringe?"

"My meat is never filled with water, where is the syringe!" the boss said angrily.

As for what kind of pneumothorax, the 120 ambulance is so far away from him, far less simple and direct than water injection.

Zheng Ren is speechless, this is so special!

The waiter's face was getting worse and worse, no matter how much Zheng Ren comforted him, his breathing became more and more rapid.

"Have you cut the bag?" Although Lao He knew if he didn't, he still asked subconsciously.

Fortunately, Boss Zheng asked for a 120 ambulance with a chest bottle and waited a few minutes for the ambulance to arrive.

Go in under closed drainage, and the patient will be fine.

This is a trivial matter, a trivial matter, Lao He comforted himself.

But before I heard the hoarse sound of the 120 ambulance, the young waiter was exhausted, sweating profusely, and his lips were blue and purple, like a fish thrown on the shore, trying his best to open his mouth to breathe the air.

"Calm down! Don't work so hard, take it easy, take it easy." Zheng Ren anxiously comforted the waiter while looking around for something handy.

If not, you can only buy it from the system space.

But under the watchful eyes of the public, it would be fatal to conjure something with empty hands.

Zheng Ren gritted his teeth, his masseter muscles bulged high, and his face was serious.

"Mr. Zheng, what do you want?" Fan Tianshui came over and wanted to help.

"Syringe, go out and draw air. If you don't have a syringe, a needle will do. It'll be better if you put it in and let it out." Su Yun was also looking for something.

But the syringe...

People who carry a syringe with them are afraid that Zheng Ren would not dare to use it for the waiter.

If not, I can only use a cleaner knife, Zheng Ren thought.

Fan Tianshui thought for a while, grabbed a straw from the counter, and asked, "Mr. Zheng, is that true? It's fine if you insert it?"

"Well." Zheng Ren's eyes lit up, "Go find a knife."

"Oh." Su Yun quickly ran to the back kitchen.

Fan Tianshui hesitated for a while, picked up a straw, opened the package, and asked carefully, "Mr. Zheng, are you going to make an incision and stuff this in?"

"Um."

"Which location?"

Zheng Ren felt that Fan Tianshui said a lot today, but still pointed to the second intercostal space on the patient's left chest wall in the midclavicular line.

He then left marks there with his fingernails.

As soon as he left, Zheng Ren was stunned to see Fan Tianshui holding a straw between two fingers, stabbing the patient's chest wall like a dagger.
