Zheng Ren looked up. The color of the waiter's system panel changed rapidly from light green to red. A diagnosis appeared in Zheng Ren's eyes - tension pneumothorax.

This is a fatal disease.

Tension pneumothorax refers to the rupture of large pulmonary bubbles or large and deep pulmonary laceration or bronchial rupture. The laceration is connected with the pleural cavity and forms a unidirectional valve.

When inhaling, the air enters the pleural cavity from the crack, while when exhaling, the valve closes and the air in the cavity cannot be discharged, resulting in the increasing pressure in the pleural cavity and compressing the lung to collapse gradually.

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

The disease is acute and can easily be fatal if delayed for a period of time.

The waiter is as thin as a bamboo pole.

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

Zheng Ren suddenly stood up, released Xie Yi's hand and strode to the waiter.

"You're not feeling well?" Zheng Ren asked gently.

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

The waiter is very young and looks less than 20 years old. I was so busy that I was sweating and flushed.

But only for a moment, the blood color on his face receded like a tide, followed by a pale.

He nodded and wanted to smile to show that he was all right.

But before, there was a sharp pain in his chest. Now he began to feel chest tightness, and he began to breathe rapidly.

Zheng Ren knows that this is the natural reaction of the body.

In the state of hypoxia, naturally inhale hard, just like in the plateau area with an altitude of 4000 meters.

But the more you inhale, the more gas appears in the chest, and the faster the lung tissue compresses.

The lung tissue is quickly flattened, resulting in increased dyspnea, and the patient will continue to breathe hard.

This is a negative feedback process, which is also the reason why patients with tension pneumothorax have a high risk of death.

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

"What are you doing?" The people sitting there also carried wine bottles. It seemed that they were drunk at seven or eight points. They looked unhappy and didn't know the situation at all.

"Excuse me, he is ill." Zheng Rendao.

"Why? I'm here to spend." The man roared with wide eyes.

Su Yun came over with a chair and helped the waiter sit down with Zheng Ren. He didn't pay attention to the middle-aged man next to him.

There's no point in arguing at this time.

Besides, he was right. He came to dinner, not a doctor. He didn't know what had happened.

Even the doctor, no one knows what happened except Zheng Ren.

Holding the waiter to sit down, Zheng Ren tore open his coat and stuck his ear to it.

"Spontaneous pneumothorax?" Lao he stood up and asked in some doubt.

"It may be that the boss is doing a physical examination." Su Yun then turned back and asked, "Xiao Feng, do you have a stethoscope?"

Feng Xuhui was dumbfounded.

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

Besides, with the scope of boss Zheng's operation, I'm afraid a first-aid kit alone is not enough.

Su Yun was also very sorry. He saw Zheng Ren look up and began to percussion.

The left hand is placed on the waiter's chest wall, and the middle finger of the right hand beats the middle finger joint of the left hand to shock the patient's chest wall, and there is a sound of percussion.

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

The most basic chest surgery physical examination. If he can't hear it, he can wash and sleep.

Lao he also heard something unusual and said in dismay, "it's really pneumothorax."

With that, he took out his cell phone and began to dial 120

"Lao he, you'd better bring a breast bottle when you call 120." Zheng Ren said in a deep voice.

"Tension pneumothorax?!" Su Yun asked.

Zheng Ren nodded.

The surrounding diners looked at what had happened and talked about it one after another.

"What happened to the waiter?"

"I don't know. Tut Tut, the clothes are torn. The young man still has this hobby? It's harassment. It's immoral in broad daylight."

"Why didn't the man fight back? The waiter can't be bullied. It's too much!"

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

The boss also came out from the inside and asked with a puzzled face, "what's the matter? Is this?"

"He had a sudden pneumothorax... He was very ill and had called 120 ambulance." Zheng Ren said, "do you have a syringe?"

"My meat is never filled with water. Where's the syringe!" The boss said angrily.

As for what pneumothorax, 120 ambulance is so far away from him, far from being simple and direct.

Zheng Ren is speechless. It's so special!

The waiter's face became worse and worse. No matter how Zheng Ren comforted him, his breathing became faster and faster.

"Do you have a cut bag?" Although Lao he knew he didn't, he subconsciously asked.

Fortunately, boss Zheng asked for a 120 ambulance with a breast bottle. Just wait a few minutes for the ambulance to arrive.

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

This is a small thing. Lao he comforted himself.

But I haven't heard the scream of the 120 ambulance yet. The young waiter was weak, sweating profusely, and his lips were blue and purple. He tried to open his mouth and breathe the air like a fish thrown ashore.

"Calm down! Don't try so hard, relax, relax." Zheng Ren anxiously comforted the waiter and looked around for something to take advantage of.

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

But in full view of the public, it's fatal to change things with empty hands.

Zheng Ren clenched his teeth, his masseter muscles bulging high, and his face was serious.

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

"Syringe, draw air out. Without a syringe, a needle is OK. Insert it and let it out." Su Yun is also looking for something.

But syringes

The person who carries the syringe with him is afraid to take it out. Zheng Ren doesn't dare to use it for the waiter.

If you can't, you can only use a clean knife, Zheng Ren thought.

Fan Tianshui thought for a moment, grabbed a straw from the cash desk and asked, "President Zheng, is it like this? Just plug it in and it'll be all right?"

"Yes." Zheng Ren's eyes brightened, "find a knife."

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

Fan Tianshui hesitated for a moment, picked up a straw, opened the outer package, and carefully asked, "President Zheng, are you ready to cut and put this in?"

"Yes."

"Where?"

Zheng Ren felt that fan Tianshui said a lot today, but he still pointed to the second intercostal space of the middle clavicular line of the patient's left chest wall.

Then he left traces with his nails there.

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