If it is a small amount of pneumothorax, the physical signs are generally not obvious, especially when patients with emphysema develop pneumothorax, it is difficult to detect any signs. However, when a larger amount of pneumothorax occurs, inspection will reveal that the affected side of the chest is bulging and respiratory movements are reduced. Upon palpation, the trachea usually shifts towards the healthy side, tactile fremitus on the affected side is reduced, percussion results in hyperresonance or tympany, and auscultation shows reduced breath sounds, which can disappear in severe cases.

Pneumothorax should be seen by which department?

If it is the patient's first pneumothorax occurrence and they are relatively young with no obvious lung bullae on the surface of their lungs, then seeing the emergency department should be sufficient to resolve the issue. Generally, if less than 20% of the lung is compressed, the patient can simply breathe oxygen at home or at a community hospital to gradually recover. However, if the patient is older and the degree of pneumothorax exceeds 20%, even reaching above 30%, it is advisable to insert a small tube between one and two millimeters into the pleural cavity to extract the air. At this point, it is recommended to consult thoracic surgery. After the air is released, a CT scan is also necessary to check for obvious lung bullae or small tears on the lung surface. If a small tear is found, it is best to use minimally invasive thoracoscopy to suture or seal the tear to prevent recurrence. Therefore, if possible, directly consider consulting thoracic surgery for pneumothorax; if thoracic surgery is not available, then consider seeing the emergency department.

Spontaneous pneumothorax and the difference between pneumothorax.

Simply put, spontaneous pneumothorax is a type of pneumothorax. In the classification of pneumothorax, besides spontaneous pneumothorax, there are also traumatic pneumothorax and iatrogenic pneumothorax. Traumatic pneumothorax is caused by direct or indirect injury to the chest wall, while iatrogenic pneumothorax occurs during medical diagnosis and treatment. Spontaneous pneumothorax often involves underlying lung diseases, such as emphysema, lung bullae, tuberculosis, lung cancer, and pneumoconiosis. It can also occur in healthy individuals without obvious lung abnormalities, typically seen in tall, thin males of young to middle age.

Pneumothorax clinical manifestations

Pneumothorax is primarily caused by various factors, both internal and external to the lungs, leading to a significant accumulation of gas within the chest cavity. Patients exhibit symptoms such as chest tightness, breathlessness, including coughing, chest pain, and other related symptoms, which are collectively referred to as pneumothorax. Patients with pneumothorax can be classified into mild and severe types. Generally, after the onset of pneumothorax, patients who only experience symptoms like panting, chest tightness, chest pain, or coughing, but maintain stable blood pressure and heart rate, are considered to have a mild condition. However, if in addition to these respiratory symptoms, the patient clearly exhibits a drop in blood pressure, a decrease in oxygen saturation, or a reduction in heart rate, these conditions are considered severe and require urgent treatment.

Foods to avoid with pneumothorax

We know that the lung tissue of a normal person is like a balloon. When breathing, this balloon expands and contracts, and there are about hundreds of millions of small structures in the lungs like balloons, which we call alveolar tissue. This structure also continuously expands and contracts, expelling carbon dioxide and inhaling oxygen. For certain reasons, such as infection or due to the body shape of tall, thin young people, or chronic obstructive pulmonary disease (COPD) and bronchitis in elderly people, this alveolar structure can rupture, causing some alveoli to merge into a large bulla. Of course, if the large bulla eventually ruptures, the break in this balloon-like surface will leak air into the pleural cavity, causing a pneumothorax. As for the nutrition from food, we believe that patients should not refrain from certain foods, but should instead increase their intake of protein, such as eating three to four egg whites daily. If worried about high cholesterol, discard the yolk, consuming only one yolk per day, but ensuring adequate protein intake. Therefore, for patients with pneumothorax, it is not about avoiding certain foods, but about eating more of those foods to which they are not allergic, such as shrimp and beef, rather than restricting their diet.

How long after a pneumothorax can the drainage tube be removed?

Pneumothorax occurs when the pleura ruptures and gas enters the pleural cavity. After the occurrence of pneumothorax, chest drainage by inserting a tube into the pleural cavity to remove the air is a common treatment. Generally, in most cases, after effective drainage for a few days, the lung can re-expand and the rupture can heal. Under these circumstances, it is common to clamp the drainage tube and observe for about two days. Then, a chest X-ray is re-examined and if there is no air, the tube can be removed. If air reappears after clamping, continued drainage is necessary. If the rupture does not heal and pneumothorax remains unresolved even after two weeks of drainage, and if the patient's physical condition allows, surgical treatment may be considered.
