Chapter 151 Why Do People Get Nosebleeds (Part [-])

In fact, at this time, the misunderstanding of this matter has been clarified. In fact, it was not Yang Tian who hurt people violently. Negotiating is more powerful.

It stands to reason that now Yang Tian has started to popularize science knowledge. The manager, Mr. Qin, and the ten security guards can already retreat. After all, the crisis has passed, and they don't understand those professional terms very well. It's useless to stick to it, and it's almost enough to leave a few waiters to clean up the mess.

The ten security guards thought so too, so they looked at the fat manager.

The chubby manager thought so too, so he looked at Mr. Qin, and just as he wanted to say something, Mr. Qin waved his hand first, "Don't panic, just listen."

All right, the world is big, you are the biggest, Old Deli Qin, since you have spoken, no one really dares to leave.

Of course, there are not only ten security guards in the capital Delhi, and nothing will happen here for ten days and a half months. Don't worry too much about the lack of security forces. The fat manager didn't say anything, just looking at the moment After a while, I couldn't go in to clean up the mess, so I let the waiter girl go to work first.

So for a while the situation was a bit weird, everyone was listening to Yang Tian talking there and did not leave, and not only that, those diners who were hiding in the private room to inquire about the situation also came out impatiently, chattering Caught in front of the private room where Yang Tian and the others were.

When seeing so much blood, the first reaction of the diners was to be frightened, but in a blink of an eye, everyone was very calm, so they also calmed down. Although there was a little more blood, it seemed that the atmosphere was very harmonious and there was nothing wrong with it!
Sometimes people just follow the crowd blindly.

Yang Tian looked at the crowds gathering outside and blinked, then opened the corners of his mouth and smiled. The scoring criteria for popular science series tasks given by the system included the scope of popularization. The more people, the better. It's a good thing for the crowd to watch!
So Yang Tian directly ignored Liang Yujian's expression and continued happily.

"Let's not talk about why an ambulance was called, but let's talk about the nosebleed."

"Nosebleeds, the scientific name epistaxis (nǜ), also known as epistaxis, usually refers to a symptom of blood flowing out of the nostrils due to the fragile capillaries in the nostrils. It is a difficult medical disease. .”

"When the nasal cavity is too dry, the capillaries inside will rupture, causing bleeding. From a clinical point of view, 90% of nosebleeds are vascular bleeding caused by blood vessel rupture."

Yang Tian glanced at Brother Deng, "This buddy's nosebleed has been there since he was a child, right?"

"In fact, most of the epistaxis in children occurs in the nasal septum, which is here."

Yang Tian pointed to his nose, the nasal septum is the part between the two nostrils.

"The nasal septum divides the nasal cavity into two parts, the left and the right. It is composed of bone, cartilage and mucous membrane, and is lined with mucous membrane and skin. Generally speaking, most people's nasal septum is not particularly straight, and tends to be biased to one side, generally the left side. , you can touch your own."

So everyone naturally stretched out their hands to touch their noses, not only the little fat guy and the eldest brother were touching, but also many diners who came outside to join in the fun raised their hands.

Many people reacted suddenly after touching their noses, hey, why am I so obedient?

Then when he looked at Yang Tian, ​​he felt a little inexplicable. What this kid said seemed to be quite serious, and it was really the case.

So the onlookers just stayed, and a small group of people gathered in the corridor.

Then those diners who didn't come out with the cat in the private room looked, where did the big guys gather?I also went to have a look, and then more and more people gathered outside the private room.

Yang Tian took the time to take a look outside, it took less than 5 minutes, and there were already heads of people outside, probably at least a dozen NO.20 people.

Very good, very good, this evaluation should be good, right?
Yang Tian cheerfully continued, "The anterior and lower mucosa of the nasal septum is rich in vascular anastomotic plexus, and about [-]% of epistaxis occurs here. Clinically, we call this bleeding-prone area, or Little area and Kiesselbach area."

"There is a layer of pink mucous membrane in the nasal cavity, and rich blood vessels are distributed on the mucous membrane. When the outside air is inhaled, the nasal mucous membrane has the function of heating, warming, humidifying and filtering air. The climate is dry, and the nasal mucous membrane is easy to dry, scab and even bleed .”

"And some children like to pick their nostrils with their fingers, which can easily damage the nasal mucosa and cause bleeding."

Yang Tian cheerfully explained, everyone listened cheerfully, and the aunt who was holding her child frowned when she heard this, she stretched out her hand and grabbed the finger that was about to poke her child's nose.

"Listen carefully to what brother said, your nosebleeds are always because you can't control your hands!"

Yang Tian continued, and pointed to Brother Deng to show everyone, "In most cases, nosebleeds can be treated on their own. For example, the buddy you mentioned used to have nosebleeds often, as long as the bleeding is stopped in time."

"Nosebleeds are not terrible, but if you are too nervous, your blood pressure will rise and the bleeding will worsen. Why did this guy have such a severe nosebleed just now? It should have something to do with being emotional."

It turned out to be the case.

Everyone nodded in a sudden realization, and then the little fat man started to ask again, "Yang Tian, ​​you still haven't mentioned why you called an ambulance?"

"Don't worry, I'm about to say it."

Yang Tian paused, then looked at Liang Yujian, "First, I want to ask the senior a question."

"what is the problem?"

Liang Yujian felt a little faint.

"This buddy heard that he has had nosebleeds for many years, so do you know that he has been checked in the hospital? What is the result of the test?"

"I..." Liang Yujian was at a loss for words for a while, Brother Deng had always been a dog-legged figure to him, how did he know if Brother Deng had been to the hospital, and what was the result of the examination?

"Okay, I see." Yang Tian nodded, with a hint of disappointment flashing in his eyes.

Sure enough, there are fewer and fewer medical students with such quality and morality as myself.

Taking a deep breath, Yang Tian's face became serious.

"What I just said is just the cause of nosebleeds in most cases, but in fact, besides dry air, there are many factors that can cause nosebleeds."

"For example, trauma, severe nose fractures can cause nosebleeds, and sometimes a bad sneeze can cause nosebleeds."

"Drugs can also be a trigger for nosebleeds. Medications that interfere with blood clotting can cause the nose to bleed profusely after a minor trauma. Likewise, anticoagulants such as heparin or warfarin or anti-inflammatory drugs such as aspirin or ibuprofen can reduce the amount of blood in a nosebleed. quantity."

The aunt holding her child's hand outside the private room's eyes lit up, and quickly took out the small notebook in the bag to remember, she didn't understand what heparin and warfarin were, but weren't aspirin and ibuprofen the medicines at home? ?A cold medicine and a painkiller, I didn't expect there to be such a use.

Over there, Yang Tian continued, "In addition to this, diseases and genetic factors are also the cause of nosebleeds. Overheating in the sun, drinking too much alcohol, overwork, stress, high blood pressure, etc. may all cause nosebleeds."

"and."

Yang Tian paused, his eyes stayed on Brother Deng, and then continued to turn to Liang Yujian, "Normal nosebleeds are complications of the cardiovascular system, internal organs, various infections, blood diseases and other diseases."

"When the body knows that it has a serious disease, it will often try to give people a reminder. Frequent nosebleeds are a reminder, and you don't even know if he has been checked in the hospital."

"I don't think you're right, either as a medical student or as a friend."

Yang Tian fixedly looked at Liang Yujian who was blushing, and what he said was resounding.
