Chapter 2302 [2302] Much more reliable
is a super cute boy, and it makes people feel less like a scholar.
Maybe for this reason, Duan had to bow his head for a long ti as if he was holding a pipa and covering his face.
Sotis it's not ugly to be ugly, but to be special is also a "sin".
"It doesn't matter, you talk first." Dr. Cheng Yuchen encouraged the younger generation of his school.
What are you afraid of, the seniors are here.
After receiving this order, classmate Duan Sanbao tapped the notebook in his hand with the pen in his hand, and said in a low voice, "There are three suspicious points that need to be carefully identified. The heart-to-chest ratio is wrong, more than one to two."
Xueba's speech is different, his tone is low and steady, not as high-profile as the boy just now. The content of the words is even more solid, and it is definitely not a random guess about what age group.
Ok? The people of this country seem to be a little bit of a scholarly tyrant. Zhao Zhaowei and the others thought.
What is the cardiothoracic ratio. Like the width of the pneumothorax line, it is necessary to find accurate anatomical landmarks on imaging before asuring. It is estimated that a little bit of light can knock out poor dical students. There are so many books to read in dicine that it is difficult to rember them all at once.
Students who rember the knowledge points look for the questions pointed out by Duan on the film.
"Look for the diaphragm first, right?" Zhao Zhaowei asked, sticking to Zhang Desheng's ear.
"Go back and read the book." Zhang Desheng stared back at him. For students who haven't read well, Xueba classmates also have no ti to teach. This is all basic knowledge.
"I'm not sure so I'm asking you, it's not that I can't rember." Zhao Zhaowei complained.
"Don't be so unconfident, okay, this is soone else's territory." Zhang Desheng twitched his eyelids at him.
In front of the opponent, you must be swollen and fat. You can't stress that you don't rember well and say you're not good at it.
To know the cardiothoracic ratio, you first need to know the transverse diater of the heart and the inner diater of the thorax. Divide the two to obtain the cardiothoracic ratio.
As Mr. Zhao said, first try to find the anatomical landmark on the right top of the diaphragm on the frontal and lateral chest X-ray and draw a horizontal diater line. The straight line distance is generally the largest thoracic inner diater distance. For the transverse diater of the heart, look at it with the naked eye and look for the distance of the transverse diater with the largest shadow of the heart.
The normal cardiothoracic ratio is 0.5, that is, the transverse diater of the heart is half of the inner diater of the thorax. In pediatrics, it should be noted that children under three years of age will be larger than this ratio, which is about 0.6, due to the oblique transverse position of the heart. Other tis it is not a ratio of 0.5 and careful consideration should be given to excluding patients for unhealthy conditions. Generally speaking, the cardiothoracic ratio is larger than the normal ratio. According to the formula, it is likely that the molecule is too large, which ans that the heart is enlarged. Based on this, it can be suspected that the patient has the characteristics of heart disease. If the molecule is too small and the thoracic cage becos smaller, you can refer to the ratio between the upper organ and the thoracic cage to determine whether the thoracic cage becos smaller. This possibility is lower than that of the heart.
Does this patient have a heart attack? Looking at the film, everyone can be sure that the evidence Duan has found is far more reliable than the boy's suspicion of tuberculosis before.
I saw that among the crowd who had listened to Duan’s words, the seniors were quite agreeable. Dr. Cheng Yuchen nodded and said, "You can talk about it."
Student Duan's statent has three suspicious points, and now only the first point is ntioned.
The others were waiting for Duan to speak.
