"The system reminds the host that this product will not be allowed to be purchased again for three weeks after purchase, do you confirm this purchase?"

Yang Tian was stunned for a moment, if he was not mistaken, when he checked this "diagnostic skill" before, the following introduction seemed to be "You must not use it again within seven days after the last use", how could it triple in the blink of an eye?

Despite this, Yang Tian did not hesitate and quickly chose to confirm. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Of course, the complaints in my heart are indispensable.,Since the system upgrade,Anyway, he hasn't been able to catch it well.,It's like the limitation of this enhanced version.,It hasn't come before the upgrade!

People's systems are upgraded monthly, the more powerful they are, the more they upgrade, the more restrictions they have?

Spit and complain, the patient still has to be observed.

According to the consistent urine of the system, the diagnosis will not come out so quickly, and Yang Tian began to judge the condition by himself.

He didn't rush forward at the first time, but first observed from the sidelines, at least to get enough information before he could start acting, otherwise your behavior may not be to save people but to harm people.

Think about it, if people have nothing to do, but your condition has been aggravated by you, and you have been stunned for half an hour and have made you semi-disabled, then you will really die!

Yang Tian carefully observed the little boy's reaction.

"Ahem! Ahem! ”

Coughing, a violent cough.

The little boy coughed breathlessly, his face seemed to be red, his hands covered his chest, and his facial features were wrinkled together on his little face, which was uncomfortable to look at.

Yang Tian looked at his expression carefully, listening to his cough and obviously rapid wheezing, his brain began to spin extremely fast.

He was recalling what he had learned in diagnostics.

Coughing is actually a reflex defense action, which can clear respiratory secretions and airway clothing, but coughing also has negative aspects, such as spreading respiratory infections, severe coughing can also lead to respiratory bleeding, and even induce spontaneous pneumothorax.

The little boy in front of him who was coughing violently was obviously suffering from such a problem.

The nature of cough can be divided into two kinds according to whether there is phlegm or not, such as a little boy coughing violently, but Yang Tian didn't see him cough up any phlegm for a long time, which can be called dry cough.

Dry cough or irritating cough is common in acute or chronic pharyngitis, laryngeal cancer, early stage of acute bronchitis, tracheal compression, bronchial foreign body, bronchial tumor, pleural disease, primary pulmonary hypertension, and mitral stenosis.

Moreover, the little boy did not show symptoms of coughing in the car before, but suddenly began to cough violently, this episodic cough can be seen in whooping cough, bronchial tuberculosis, and bronchial asthma (variant asthma) with cough as the main symptom.

As for the timbre of the cough......

Well, even if Yang Tian took two steps forward and got a little closer, he didn't hear anything abnormal, neither hoarse nor like a rooster's crowing, nor a metallic sound, it sounded quite loud......

At this time, there were already onlookers who couldn't help but step forward, Yang Tian glanced at it, it was the old lady who gave way to himself on the bus just now.

The old lady walked tremblingly, but her face was very anxious, and while muttering, "What's wrong with you, child?", she turned to the other onlookers, "Is there a doctor, is there a doctor!" ”

Yang Tian glanced at it and found that a few people had already taken out their mobile phones and started calling, the fastest were the two girls with headphones, the headphones simply didn't take off, and they were already reporting the location to the opposite side at this time.

The middle-aged man in the suit also hung up the official phone he was still making just now at this time, and when Yang Tian turned his head, he clearly saw that he had pressed three buttons, which was estimated to be 120.

Without paying too much attention to the actions of others, Yang Tian continued to get closer to observe the little boy's symptoms.

"Ahem! Ahem! ”

The little boy coughed violently and breathed violently, his hands clutched tightly to his chest.

Yang Tian, who noticed this, stared at him, and his chest hurt!

There are many causes of chest pain, but combined with other manifestations of the little boy, it is estimated that it can only be a respiratory disease, pleurisy, pleural tumor, spontaneous seven males, hemothorax, bronchitis, broncholung cancer, etc.

Among them, pleurisy is characterized by pain as soon as the patient breathes, so that he does not dare to breathe heavily, the little boy is obviously not, Yang Tian ruled out this possibility on the spot.

Getting closer again, Yang Tian had almost walked to the little boy's side, and the trembling old lady was beside him trembling and wanted to say something, but Yang Tianyi raised his hand to stop him.

He was listening to the little boy's breathing.

Mixed with a violent cough, the sound of the little boy's breathing was actually difficult to distinguish, but Yang Tian still keenly heard the clue, it was expiratory dyspnea!

The main characteristics of expiratory dyspnea are labored exhalation, slow exhalation, significantly prolonged breathing time, often accompanied by expiratory wheezing, and this is the case in young boys, who are not ambiguous at all when they inhale deeply, but it takes a long time when it is their turn to exhale.

What diseases are common with expiratory dyspnea?

Chronic bronchitis (asthma), chronic obstructive pulmonary edema, bronchial asthma, diffuse pan-bronchitis!

Yang Tian looked at the little boy in front of him who was coughing and breathing, and two words suddenly appeared in his heart: asthma!

Asthma, also known as bronchial asthma, is a chronic inflammation of the airways involving a variety of cells and cellular components.

This inflammation is often accompanied by increased airway responsiveness, resulting in recurrent episodes of wheezing, shortness of breath, chest tightness, and/or coughing, usually at night and/or early in the morning, and with sudden onset when irritated.

Air pollution, smoking, respiratory viral infections, strenuous exercise, weather changes, inhaling cold air, and even distilled water droplets can cause asthma attacks.

Yang Tian looked around, although it was summer at this time, there should be no pollen if there was no flowering, but the dust on the side of the road was really not ordinarily serious, and it was reasonable to cause asthma.

So, it's asthma, right......

Yang Tian hesitated to make a judgment in his heart, but he vaguely felt that something was wrong, his brows were already furrowed, and he stared at the little boy who kept coughing.

It had been thirty seconds since he squeezed into the crowd, and the little boy's cough had not slowed down in the slightest, and his face flushed even worse than just now, which was a clear sign of hypoxia, and the cough was so bad, the lack of oxygen was certain.

During an asthma attack, the patient often has a distended chest, and the percussion will be hyperresonant, and most patients will have a broad expiratory phase of wheezing.

Yang Tian weighed it, and felt that without a stethoscope, the little boy coughed so badly, and it seemed that he couldn't percussion and hear the sound, so he could only give up.

Breathing still sounded difficult, but it didn't sound like expiratory dyspnea anymore, and the little boy was now inhaling and exhaling at a noticeably faster rate, sounding a bit like the violent wheezing sound of a running overrun.

The emaciated body was always in a semi-curved state, and the whole upper body of the little boy was shaking when he coughed.

Yang Tian stared at every subtle movement of the little boy, and the slightest inappropriate feeling in his heart became more and more serious.

Wrong!
