What causes a pneumothorax There are many small lung alveoli inside the human lungs. If some of the small lung alveoli break, a large lung alveolus is formed, and when the lung ruptures, gas from the lung and bronchus enters the chest cavity. In this way, air accumulates in the chest cavity, and a pneumothorax is formed. Pneumothorax is common in terms of spontaneous pneumothorax and secondary pneumothorax, the former is caused by rupture of lung tissue and dirty layer of pleura due to lung lesion, or rupture of fine emphysematous vesicles near the surface of the lung, and air overflow into the pleural cavity. The latter is caused by trauma, invasive operations (such as puncture), etc. When spontaneous pneumothorax occurs, the patient will usually feel relatively severe chest pain or chest tightness, and then have difficulty breathing, which can lead to mediastinal oscillation in severe cases and endanger life. Pneumothorax “likes” thin and tall body type Sudden laughter while watching TV, occasional sneezing, violent force lifting barbell, coughing, lifting heavy objects, playing basketball, playing soccer and other strenuous sports are often the triggers of spontaneous pneumothorax. Professor Geng Qing said that spontaneous pneumothorax is most like to appear in the young and middle-aged people, especially preferring thin and tall young people, because this part of the thin and tall young people develop faster, poorly developed elastic fibers on the alveoli, poor relative elasticity of the alveoli, it is easy to rupture. In this way, thin and tall men should also pay attention to, regardless of what sports, do not exercise too fierce and violent, to avoid the alveoli pressure is too high and rupture, to avoid the occurrence of pneumothorax. Suddenly feel one side of the chest pain like a knife cut to beware of inappropriate sports, but the spontaneous pneumothorax “opportunity to take advantage of”. In this regard, Director Geng reminded teenagers, when playing sports must be alert to strenuous or inappropriate exercise, so as not to let the spontaneous pneumothorax find. In order to avoid the occurrence of pneumothorax, we should first pay attention to keep a happy mood, emotional stability, pay attention to the combination of work and rest, try to avoid strong physical labor, do not force to hold the air. Professor Geng Qing, an expert in thoracic surgery, emphasized that the recurrence rate of spontaneous pneumothorax is very high, and some patients may recur within one month after the first onset. Therefore, people who have had spontaneous pneumothorax should pay attention to the prevention of colds, especially coughs, and keep their bowels open to avoid holding their breath, and exercise should be jogging, tai chi and other sports, avoiding basketball, soccer and other strenuous sports that require sudden force. In addition, people with lean and tall bodies should be alert to the possibility of spontaneous pneumothorax if they experience chest pain and breathing difficulties after coughing violently or exerting themselves too hard, and should seek medical attention in a timely manner.
