UNDERSTANDING PNEUMOTHORAX
  1. What is pneumothorax?

A pneumothorax is a condition where air leaks through a hole in the lung, causing air to fill the pleural cavity. As the amount of leaking air increases, the lung cannot function normally. If the air in the chest cavity is not removed, the space between the lung and heart can be pushed to the opposite side, leading to a medical emergency.

  1. Causes of pneumothorax

Pneumothorax is classified into spontaneous pneumothorax and traumatic pneumothorax, requiring appropriate tests to determine the cause.

Spontaneous pneumothorax is further divided into primary and secondary pneumothorax. Primary pneumothorax occurs in healthy individuals and is caused by small air sacs in the upper membrane of the lung. The exact cause of primary pneumothorax is unclear, but it is believed to be associated with smoking, as most patients are tall, thin, and smokers. Secondary pneumothorax occurs in individuals with a history of lung disease, including tuberculosis, malignant tumors, pulmonary fibrosis, chronic obstructive pulmonary disease, and emphysema.

Traumatic pneumothorax is caused by car accidents or injuries from sharp objects, resulting in lung parenchyma damage due to chest trauma. Pneumothorax can also occur after a lung biopsy, and tension pneumothorax may be caused by medical equipment such as ventilators in intensive care units. Another cause is related to menstrual procedures in women.

  

  1. Symptoms of pneumothorax

Common symptoms of pneumothorax include chest pain and shortness of breath. Chest pain usually begins suddenly and may last for about 24 hours, with most people describing it in various ways. They often report feeling “a lump in the back” or that “every time I breathe, it feels like a sharp pain in my chest.”

Shortness of breath varies depending on the patient’s condition. Young patients without a prior history of lung disease typically do not experience severe shortness of breath. Patients with severe pneumothorax may have such difficulty breathing that they cannot breathe at all, which may be accompanied by cyanosis. A few patients report hearing a sudden “crackling” sound in their chest when lying down or sitting up after lying down, as well as a sensation of something moving.

  

  1. Diagnosis of pneumothorax

The easiest way to diagnose pneumothorax is through a chest X-ray. A chest X-ray, combined with the symptoms mentioned above, can be used to diagnose pneumothorax in most cases. Additionally, diagnosis can be based on other test results from the patient. Pneumothorax may be suspected by tapping the affected area, performing a spectral magnetic resonance, and noting decreased breath sounds during auscultation. A chest X-ray will be performed and the results will be interpreted by a specialist to confirm pneumothorax.

In recent years, high-resolution computed tomography (HRCT) of the lungs has been utilized to diagnose and establish treatment methods. The aim is to determine whether the patient with pneumothorax requires surgical intervention. However, this test is not necessary for all patients, so it is advisable to consult a specialist to determine what examinations are needed.

  

  1. Treatment of pneumothorax

The principle of treating pneumothorax is to remove the leaking air from the lungs in the chest cavity to allow for lung re-expansion, and to effectively seal the chest cavity to prevent recurrence. Treatment for pneumothorax is determined based on the patient’s condition and whether there is a recurrence. The duration of treatment for pneumothorax is difficult to predict. Most patients require treatment for about a week. Some patients may need treatment for a longer duration, even in cases of spontaneous pneumothorax. Generally, the treatment duration for secondary pneumothorax is significantly longer than for spontaneous pneumothorax, and it is challenging to choose the appropriate treatment method, so it is advisable to follow the guidance of a specialist.

  

  1. Monitor & note for pneumothorax

If a pneumothorax is initially treated with observation or simple chest tube placement, the recurrence rate is about 50%. If it has recurred twice, the risk of recurrence more than three times is approximately 80-90%. Therefore, patients with recurrent pneumothorax need to be treated surgically. The recurrence rate in patients who have undergone surgical treatment is about 5%.

In high-altitude areas, the air pockets in the lungs can easily rupture. Those who have been diagnosed with pneumothorax or who are at risk of recurrence should consult a specialist before undertaking long trips.

Deep inhalation of smoke and heavy breathing after strenuous exercise can increase chest pressure along with abdominal pressure. This pressure can easily rupture bubble-like pockets in the thin pleura, so caution is advised.
