Pneumothorax is the entry of gas into the pleural cavity, resulting in a state of air accumulation called pneumothorax.

Mostly due to lung diseases or external influences that rupture the lung tissue and the pleura of the dirty layer, or the rupture of fine emphysematous bubbles close to the surface of the lungs, air from the lungs and bronchi escapes into the pleural cavity.

Traumatic pneumothorax is caused by trauma to the chest wall or lungs; spontaneous pneumothorax is caused by disease-induced rupture of the lung tissue; and artificial pneumothorax is caused by injecting air into the pleural cavity for therapeutic or diagnostic purposes. Pneumothorax can be divided into closed pneumothorax, open pneumothorax and tension pneumothorax.

Extended information:

Prevention of pneumothorax:

1. Patients can consider participating in normal work and activities after the symptoms disappear. However, strenuous exercise and body collision exercise should be performed only after imaging suggests that the pneumothorax has completely disappeared.

2. Smoking cessation significantly reduces the recurrence of primary pneumothorax, with a relative risk reduction of approximately 40%, to aid in its successful cessation.

3. Because underwater activities such as diving can increase the recurrence rate of pneumothorax, and because pneumothorax volume increases during the ascent of a dive, increasing the risk of tension pneumothorax, the BTS guideline suggests that scuba diving should be avoided for life in patients who have not been treated with a definitive method (e.g., partial pleurodesis). For professional divers, treatment such as partial pleurodesis is required after a pneumothorax episode before resuming diving.

4, although air travel itself does not increase the risk of pneumothorax, but at high altitude can exacerbate the condition of pneumothorax, the consequences are serious, so for the pneumothorax patients who do not have closed chest drainage should avoid air travel, need to be treated or imaging data suggest that the pneumothorax is absorbed before air travel.
