Although everyone didn't have a proper understanding of the ins and outs of the matter, they all faintly felt that something was wrong at this time, and they couldn't help but nod when Yang Tian said this. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Han Bing was also nodding, although the amplitude was very small, but it was still seen by Liang Yujian.

Liang Yujian's heart ached, his blood surged, and he blurted out the words of justification, "I, I'm not a doctor, I'm just a medical student, I haven't learned so much, I don't understand these causes or anything!" ”

"Isn't it a bit difficult for you to ask me like this?"

Liang Yujian forced his composure, "Besides, I was just scared by his appearance just now, but the instructions should be correct, right?" If his nosebleed hadn't been so turbulent, it would have been stopped! ”

Isn't it normal for a normal person to have a nosebleed just raise their head and stuff a tissue, there's nothing wrong with it!

"Oh?"

Yang Tian raised his eyebrows, "Okay, then let's not talk about the cause, let's talk about your emergency treatment of this buddy just now." ”

Yang Tian's eyes narrowed slightly, he had already seen that you were unhappy, you still dare to quibble?

I originally wanted to save you some face, but since that's the case, let's break it and talk about it!

"Say, say what?"

Liang Yujian felt a little flustered again.

"Let's talk about what you just did."

Yang Tian raised his eyebrows, "First of all, you gave a total of two instructions, one, take a tissue and plug your nostrils, and two, look up." Am I right? ”

"Well, that's right." Liang Yujian nodded, then his neck was thick and his chest straightened, "My instructions are also correct!" ”

"That's right?!"

Yang Tian suddenly laughed.

"Yes, generally speaking, the first choice for nosebleeds is tamponade to stop bleeding, and sterile gauze or cotton balls will be used in the hospital, and only paper towels can be used in the poor situation here, which is true."

"That's it!"

Liang Yujian secretly breathed a sigh of relief, the expression on his face relaxed, and glanced at Xie Xin and Han Bing triumphantly, which probably means that you still have two brushes for my brother.

Yang Tian narrowed his eyes, "Are you very proud?" What I just said is the general situation, that is, the situation of normal people with nosebleeds, do you think that the nosebleeds of this guy just now are normal? ”

Liang Yujian's face froze.

Just now...... Brother Deng's nosebleeds are really not normal......

"Or do you think the tissue can really stuff and stop the bleeding in that situation?"

Yang Tian stared at Liang Yujian, a mocking smile on the corner of his mouth.

Liang Yujian held back decisively for a long time and couldn't refute.

Thinking about the situation just now, who can use a paper towel to block the faucet that opens the floodgates?

Yang Tian looked at Liang Yujian and continued.

"I noticed that this guy tried to pinch his nose and tried to stop the bleeding, but failed, which means that there is no way to determine the location of the broken blood vessels, and naturally the source of the bleeding cannot be blocked."

"In this case, the heart has a continuous supply of blood, and then it seeps out from the broken blood vessels, and then it can't find an outlet, so it can only accumulate there, what are the consequences, you should be able to imagine it, right?"

“…… Can you ......" Liang Yujian nodded silently, even if it is blocked, it will lead to blood stasis, and the faucet is made of steel and will not be burst, but Brother Deng's nose is made of meat!

Yang Tian's face returned to his flatness and continued to speak.

"Healthcare professionals need to provide effective treatments based on what they have, regardless of the circumstances."

"And the proposal you gave is obviously ineffective at such a time, not only is it ineffective, but it will also delay the time of treatment and delay the time for the patient to take the right measures!"

"Me!" Liang Yujian was excited by Yang Tian's words, his face blushed, his lips pouted for a long time, his momentum still weakened, and he said weakly, "Don't ask for merit, but ask for no fault, at least don't give wrong instructions, what are you doing so fiercely......"

"Oh?" Yang Tian raised his eyebrows and laughed angrily, "Okay, since you said that you are not at fault, then we will tell you about your next instruction and let him look up." ”

"Eh, you'll wait!" Liang Yujian's voice became louder, "Look up to stop the bleeding when you have a nosebleed, is there anything wrong with this?" Big guy comment, I also had a nosebleed when I was a child, raised my head and quickly stopped! ”

At this time, there were already quite a lot of people inside and outside the private room, Qin Lao, the four young people and the fat manager simply stood in the private room, and the aunt with her own child before also squeezed in with the child, after all, her child really likes nosebleeds recently, and many things Yang Tian said are useful to her.

As soon as she heard Liang Yujian say this at this time, the aunt should be reconciled on the spot, "Yes, I also let my child look up when he has a nosebleed, this is what my friend told me, it's very easy to use?" ”

"This is the same in my family."

At the back of the crowd, a middle-aged man also raised his hand, there was also a boy in their family, the little boy was active, often stumbled, and when he had a nosebleed, they directly asked him to tilt his head for a while and then plugged it with a tissue.

The little fat man and the boss also pricked up their ears curiously at this time, listening to Yang Tian's meaning, this should be wrong to look up, but they usually look up when they see other people's nosebleeds?

Yang Tian narrowed his eyes, "It seems that everyone usually looks up when they have nosebleeds?" ”

"Hmm!"

"That's right!"

Immediately, several people agreed, and Liang Yujian couldn't help but breathe a sigh of relief when he saw that everyone was like this. Then he looked at Yang Tian a little nervously.

Yang Tian frowned, then shook his head, "Then don't do this in the future." ”

"Why?"

Liang Yujian was anxious.

Yang Tian glanced at him lightly, directly held back the words behind him, and then continued, "When there is a nosebleed, most people are used to tilting their heads back with their nostrils facing up, so that under the action of gravity, the blood that has flowed out will accumulate in the nasal cavity, and it seems that the bleeding will stop. ”

Everyone nodded.

"But has the bleeding really stopped?" Yang Tian glanced at everyone, "No, we know that blood clotting is due to the aggregation of platelets, but when there is a large pool of blood in the place where it should be coagulated, the concentration of platelets will decrease, and the speed of blood clotting will also slow down." ”

"Moreover, because the nasal cavity and the oral cavity are actually connected, not only is it difficult to stop the bleeding by tilting the head back, but the backward posture will also cause the blood that has flowed out of the nasal cavity to flow backwards to the throat due to the relationship between posture and gravity, and will be swallowed into the esophagus and gastrointestinal tract, stimulating the gastrointestinal mucosa to produce discomfort or vomiting."

"When the bleeding is heavy, it is easy to suck blood into the trachea and lungs, causing difficulty in breathing and causing danger. Therefore, when you have a nosebleed, tilting your head back is the same as pulling seedlings to help you grow, which is harmful and not beneficial. ”

"The correct approach should be to maintain a normal upright position or lean forward slightly, so that even if there is a small amount of clot blocking the nasal passage, it doesn't matter."

"Then you should use pressure to stop the bleeding, or use decongestant or nasal spray to wet the cotton and stuff it in, and if the situation does not allow, you can use white vinegar, which is why I just asked you to take white vinegar."

Yang Tian glanced at the people with their mouths wide open, and then looked at Liang Yujian, "So, your two instructions, one is ineffective and delays the time for treatment, and the other is wrong and there is a danger of aggravating the condition, do you still think that you don't seek merit but seek no fault?" ”

"You've had a big deal!"
