In fact, at this time, the misunderstanding of this matter has been sorted out, in fact, it is not Yang Tian who broke out and hurt people, it is just that Brother Deng suddenly had a nosebleed that made everyone too frightened, and Yang Tian did not discuss it when he saved people. Pen & Fun & Pavilion www.biquge.info

It stands to reason that now Yang Tian has begun to popularize scientific knowledge, such as the manager, Qin Lao, and the ten security guards can already retreat, after all, the crisis has passed, and they don't understand those professional terms very well, so it's useless to pestle here, just leave a few waiters to clean up the mess.

Ten security guards thought the same thing, so they looked at the chubby manager.

The fat manager also thought so, so he looked at Qin Lao, and just opened his mouth to say something, and then Qin Lao took the lead and waved his hand, "Don't panic, listen and see." ”

Okay, the world is big, you are the biggest, and since your old man has spoken, no one dares to leave.

Of course, there will not be only ten security guards in this area, and nothing will happen here for ten days and half a month, so don't worry too much about the lack of security forces, and the fat manager didn't say anything, but I saw that I couldn't go in to clean up the mess for a while, so I asked the waiter to get busy first.

So for a while, the situation was a little weird, everyone actually listened to Yang Tian talking there and didn't leave, and not only that, but those diners who were hiding in the private room to inquire about the situation also couldn't bear to walk out directly, and rubbed in front of Yang Tian and the private room where they were.

When they saw that there was 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, but it seemed that the atmosphere was very harmonious and nothing happened!

Sometimes people just blindly follow the herd.

Yang Tian looked at the crowd gathering more and more outside, blinked, and then pulled the corners of his mouth and smiled, the system gave the popular science series of task scoring criteria, but there is a popularization of this item, the more people, the better, there are people who eat melons to watch, this is a good thing!

Therefore, Yang Tian directly ignored Liang Yujian's face and began to continue happily.

"Let's not talk about why we called an ambulance, let's talk about nosebleeds."

"Nosebleeds, also known as epistaxis, usually refer to a symptom of blood flowing out of the nostrils due to the fragility of the capillaries in the nostrils, after the blood vessels are damaged, and it is a medically incurable disease."

"When the nasal cavity is too dry, the capillaries inside can rupture, causing bleeding. From a clinical point of view, 90% of nosebleeds are vascular bleeding caused by vascular 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 nosebleeds in children occur in the nasal septum, which is where they occur."

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

"The nasal septum divides the nasal cavity into two parts, left and right, composed of bone, cartilage and mucous membranes, lined with mucous membranes and skin.

So everyone naturally reached out to touch their noses, not only the little fat boss and the fourth were touching, but even the diners who came outside the door to join in the fun also raised their hands.

Many people suddenly react when they touch their noses, hey, why am I so obedient?

Then when he looked at Yang Tian, he had a little inexplicable feeling, what this kid said seemed to be quite serious, and it was really like that.

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

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

Yang Tian took the time to glance outside, it was only less than five minutes, and the people outside were already full of heads, and it was estimated that there would be at least ten or twenty people.

It's good, it's good, this evaluation should be good, right?

Yang Tianle continued, "The anterior and lower mucosa of the nasal septum is rich in vascular anastomosis plexus, and about ninety percent of nosebleeds occur here, which we call clinically the bleeding-prone area, or the Little area and the Kiesselbach area. ”

"There is a pink mucosa in the nasal cavity, and the mucosa is distributed with abundant blood vessels. When inhaled outside air, the nasal mucosa has the function of heating, warming, humidifying, and filtering the air. The climate is dry, and the nasal mucosa is prone to dryness, crusting, and even bleeding. ”

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

Yang Tianle's explanation, everyone listened happily, and the aunt who was holding her child frowned when she heard this, and grabbed the finger that her child was about to poke in the nose as soon as she stretched out her hand.

"Listen carefully to what my brother has to say, you always have nosebleeds because you can't control your hands!"

Yang Tian continued, and pointed at Brother Deng with his finger to signal to everyone, "In most cases, nosebleeds can be dealt with by themselves, for example, this buddy you said used to have nosebleeds a lot, as long as the bleeding is stopped in time." ”

"Nosebleeds are not terrible, but if you are overly nervous, your blood pressure will rise and the bleeding will be aggravated.

I see.

Everyone nodded in realization, and then the little fat man began to ask again, "Yang Tian, you still haven't said why you called an ambulance?" ”

"Don't worry, I was about to say."

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

"What...... Issue? ”

Liang Yujian was a little weak.

"This guy has heard that he has had a nosebleed for many years, so do you know that he has been to the hospital for a check-up? What are the results? ”

"I ......" Liang Yujian was speechless for a while, Brother Deng has always been a dog-legged character to him, how does he know if Brother Deng has been to the hospital, and what are the test results?

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

Sure enough, there are fewer and fewer medical students who are as moral as themselves.

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, there are many factors that can cause nosebleeds in addition to dry air."

"For example, trauma, a severe nose fracture can cause nosebleeds, and sometimes a sneeze that is not too big can also cause nosebleeds."

"Medications can also be the trigger for nosebleeds, interfering with blood clotting drugs that can cause the nose to bleed heavily after minor trauma. Similarly, anticoagulants such as heparin or warfarin or anti-inflammatory drugs such as aspirin or ibuprofen can reduce the amount of blood in the nosebleeds. ”

The aunt who was holding her child's hand outside the private room had a bright eye, and quickly took out the small notebook in the bag and remembered that she didn't understand what heparin and warfarin were, but aspirin and ibuprofen are not the medicines that are available at home? A cold medicine and a painkiller, I didn't expect this kind of use.

Yang Tian continued, "In addition, diseases and genetic factors are also the causes of nosebleeds, such as excessive sun exposure, excessive drinking, overwork, stress, high blood pressure, etc. ”

"And."

Yang Tian paused, his eyes lingered on Brother Deng, and then continued to turn to Liang Yujian, "Frequent nosebleeds are a complication of the cardiovascular system, internal organs, various infections, blood diseases, and other diseases. ”

"When the body knows that it has a major disease, it often tries to give people a hint, and frequent nosebleeds are a hint, and you don't even know if he has been to the hospital for a check-up."

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

Yang Tian looked at Liang Yujian, whose face was flushed, and what he said was loud.
