Chapter 2299 [2299] Meaning

On the x-ray, the lung field on one side is divided into three zones from the periphery to the hilum, the outer, middle and inner zones.

Under normal circumstances, there are lung markings in the lungs. They occupy a large area of ​​the lungs to 90%, and it can be said that they basically represent the lungs. Lung markings are the projections formed by the blood vessels, lymphatic vessels, bronchi, etc. of the lungs under the X-ray machine. We know from anatomy that these structures of the lungs are like branches and forks branched off from a big tree, with lines and branches intertwined. The image presented in imaging is the same, like the texture on the surface of the object, so it is called lung texture.

In the event of pneumothorax, the lung is compressed, and the inner lung belt must move down and inward, which can show the result of being compressed with visible lung markings on imaging.

Where there is no lung marking, the area on the x-ray will become translucent, and a boundary line with the lung marking area is formed, which is the pneumothorax line. This is the principle of the pneumothorax line. Anatomically, this line is also the pleural line.

Spontaneous pneumothorax is a common clinical case. Like Xie Wanying who encountered an emergency patient in a car accident, there is no condition for not being in the hospital. According to the usual practice, it is necessary to take a film after initial suspicion of pneumothorax and then deal with it.

is equivalent to saying that filming and watching films is of great significance to the diagnosis of pneumothorax. The following will explain what is going on.

Finding pneumothorax lines on X-rays is a common medical knowledge for this disease. As long as medical students encounter this disease in the clinic, they must learn and learn.

The greatest significance of   pneumothorax line is that the width of the air belt can be measured according to the position of the pneumothorax line. The width of the pneumothorax is another proper noun. As the name suggests, it is the width of the area without lung markings (the gas-liquid area) outside the pneumothorax line (the displaced pleural shadow).

Measuring this width can further estimate the proportion of the patient's affected lung that is collapsed.

Here is a rough comparison table: When the air belt width is a quarter of the patient's thorax, the lungs are compressed to about 35 percent. When the air belt is one-third the width of the patient's thorax, the lungs are compressed to fifty percent. When the air belt width is one-half the width of the patient's thorax, the lungs are compressed by 65 percent. If the width of the air belt reaches two-thirds of the patient's thoracic cage, it is a super early warning: the patient's affected lung is compressed to 90 percent.

Wei Shangquan stammered and continued: "At present, the patient's left pleural line is displaced, and the width of the air belt is estimated to be less than one-third of the thorax, so the patient's left lung is about 40% collapsed."

What is the significance of calculating the volume of this lung compressed?

Inspection reports are to be used as the basis for further guidance in formulating clinical treatment strategies. The results of the compression ratio of the lungs are also published for this purpose, as medical evidence for the treatment of patients.

Doctors cannot treat patients without evidence. What means to use, how to treat, and to what extent, all depend on the evidence. This is what Xie said to Hu Hao before.

The disease of spontaneous pneumothorax is a bit special. For patients with primary spontaneous pneumothorax, these patients have no other diseases, and the age group of the disease basically belongs to the young and middle-aged. These two characteristics indicate that the cause of the patient may be accidental, and that the young body has a strong metabolism and is easier to repair the body by itself than the old patient. These factors are destined to be a disease that can self-heal on its own.
