Pneumothorax is a very common type of disease, caused by many and complex factors. It is classified into three different types based on individual conditions, so different types of pneumothorax lead to different clinical symptoms and consequences for the patient. Usually, it is not advisable to measure lung capacity immediately after a pneumothorax occurs. For lighter cases, it is recommended to wait at least half a month before measuring lung capacity. If the pneumothorax is severe, the interval may need to be over a month before conducting lung capacity measurements. Therefore, while patients with pneumothorax can have their lung capacity measured, this should only be done once the condition is effectively managed.

The difference between tension pneumothorax and open pneumothorax.

The main difference between a tension pneumothorax and an open pneumothorax lies in the relative pressures of the pleural cavity compared to the atmospheric pressure. An open pneumothorax occurs when the pleural cavity is in an open state due to some reason. During inhalation, gas can enter the pleural cavity, and during exhalation, the gas can be expelled through this opening or another opening, resulting in pleural cavity pressure that is roughly equal to the atmospheric pressure. In a tension pneumothorax, due to some reason, a one-way valve is formed. The gas enters the pleural cavity easily but encounters resistance during expulsion, causing the pressure in the patient's pleural cavity to increase progressively. The gas can only enter the pleural cavity and cannot be effectively expelled. Therefore, the main difference between a tension pneumothorax and an open pneumothorax is the level of pleural cavity pressure compared to atmospheric pressure; in a tension pneumothorax, the pressure in the pleural cavity is significantly higher than the atmospheric pressure, while in an open pneumothorax, the pressures are roughly equal.

Pneumothorax, which department should it go to?

Which department is better for pneumothorax treatment? There isn't a strict definition dictating which specific department one must visit for pneumothorax. Generally, you can visit the respiratory department or the cardiothoracic surgery department. If the patient's condition is very severe, then the first choice should be the emergency department, where emergency treatment can be provided before further referral.

Can pneumothorax heal by itself?

Pneumothorax is caused by a rupture of the pleura, allowing air to enter the pleural cavity, and it is relatively common clinically. Can pneumothorax be cured after it occurs? It depends on the specific circumstances. If it is a closed pneumothorax with a small amount of air accumulation, conservative treatments like rest and oxygen therapy can allow for self-healing of the pneumothorax. However, in most cases, the accumulation of air is generally significant, and often it is a tension pneumothorax. In these instances, treatments generally involve pleural cavity puncture, or closed pleural drainage to drain the air, making it difficult to heal spontaneously and requiring medical treatment. Moreover, some patients may not recover fully despite aggressive treatment and may require surgical intervention.

How to treat recurrent pneumothorax for the second time?

Patients with recurrent pneumothorax, we recommend proactive minimally invasive surgical intervention. For patients experiencing their first recurrence of pneumothorax, the likelihood of a second recurrence is about 20-30%. For those who have had two episodes of pneumothorax, it indicates the presence of a small rupture on the lung, or an area that has not healed well, or is particularly weak. Thus, for patients who have had two episodes or a second occurrence of pneumothorax, if they do not receive active treatment, the probability of a third recurrence rises to about 70-80%. Whether using minimally invasive surgery or the conservative method of simple tube insertion, both are certainly burdensome for the patient. However, for patients with a second occurrence of pneumothorax, undergoing a small minimally invasive surgery, which involves a small incision of one to two centimeters under the armpit to treat the pneumothorax, dramatically reduces the likelihood of subsequent occurrences from the previous 70-80% to below 10%. Therefore, the best treatment for a second pneumothorax episode is through minimally invasive surgical intervention.

Pneumothorax should be registered under which department?

What department should you register for pneumothorax? If pneumothorax occurs suddenly, the condition is generally severe with significant breathing difficulties. In such cases, we recommend prioritizing a visit to the emergency department. Once the emergency department receives the patient, they will immediately request a consultation with a thoracic surgeon or a respiratory specialist. If the patient requires surgery, such as thoracic closed drainage or other procedures, it is usually handled by a thoracic surgeon; if the patient only requires conservative treatment, they will likely be transferred to the respiratory department; if the patient's condition is critical, they might be admitted to the ICU.
