Pneumothorax, commonly called a collapsed lung, is a condition in which air enters the space between the lung and the chest wall. This space is called the pleural space. Normally, the pleural space contains only a very small amount of fluid and helps the lungs move smoothly during breathing. When air enters this space, it can put pressure on the lung and cause part or all of the lung to collapse.
A pneumothorax can happen suddenly and may range from a small collapse that causes few symptoms to a severe collapse that makes breathing difficult. In some cases, the condition develops without an obvious cause, while in others it occurs because of an injury, lung disease, or a medical procedure.
A small pneumothorax may sometimes improve on its own as the body gradually absorbs the trapped air. Larger or more serious pneumothorax cases may require medical treatment to remove the air and allow the lung to expand again.
Pneumothorax can affect one or both lungs, although it usually affects one side at a time. It may occur in healthy people, particularly tall and thin young adults, but people with existing lung conditions may also be at higher risk.
A severe form called tension pneumothorax occurs when air continues to enter the pleural space but cannot escape. Pressure builds rapidly inside the chest and can affect the lungs, heart, and circulation. Tension pneumothorax is a medical emergency and requires immediate treatment.
Diagnosis is usually made through a medical examination and imaging tests such as a chest X-ray. In some situations, a CT scan or ultrasound may be used.
Treatment depends on the size and cause of the pneumothorax and the person's symptoms. Options may include observation, oxygen, needle aspiration, or insertion of a chest tube to remove trapped air. Surgery may be needed when pneumothorax keeps coming back or does not heal properly.
Anyone with sudden chest pain or unexplained difficulty breathing should seek medical attention promptly because pneumothorax can become serious if untreated.
Pneumothorax occurs when air enters the pleural space between the lung and the chest wall. The trapped air creates pressure on the lung and can cause it to partially or completely collapse.
There are several different causes of pneumothorax. One type is called spontaneous pneumothorax, which occurs without a major chest injury. Primary spontaneous pneumothorax can happen in people who do not have a known lung disease. It is more common in tall, thin young adults and may occur when a small air-filled area on the surface of the lung ruptures.
Smoking increases the risk of spontaneous pneumothorax because it can damage lung tissue. People who smoke may be more likely to develop weak areas in the lungs that can rupture and allow air to escape into the pleural space.
Secondary spontaneous pneumothorax occurs in people who already have a lung condition. Conditions such as chronic obstructive pulmonary disease, asthma, pneumonia, tuberculosis, cystic fibrosis, and certain other lung diseases can weaken lung tissue and increase the risk of pneumothorax.
Chest injuries can also cause pneumothorax. A strong impact to the chest, broken ribs, penetrating injuries, or other trauma can damage the lung and allow air to enter the pleural space.
Certain medical procedures may occasionally cause pneumothorax. It can happen after procedures involving the chest or lungs, placement of certain medical lines, lung biopsy, or mechanical ventilation. Healthcare professionals take precautions to reduce this risk.
A pneumothorax can also develop when pressure inside the lungs becomes very high. This may happen in people receiving mechanical ventilation, particularly when high pressures are required.
Sometimes a pneumothorax can occur during activities involving significant pressure changes, such as scuba diving or air travel, particularly in people who already have a lung problem or an existing pneumothorax.
Genetic or connective tissue disorders may increase the risk of repeated pneumothorax in some individuals. Some people also experience recurrent pneumothorax without a clearly identifiable cause.
The exact cause is important because it can influence treatment and the risk of recurrence. Doctors may use medical history, physical examination, chest X-ray, CT scan, or other tests to determine why a pneumothorax occurred.
Avoiding smoking, treating underlying lung diseases, and following medical advice can help reduce the risk of pneumothorax in people who are vulnerable to the condition.
Not every case of pneumothorax can be prevented, especially when it occurs spontaneously or because of an underlying medical condition. However, certain steps can reduce the risk or help prevent another episode in people who are at higher risk.
One of the most important preventive measures is avoiding smoking. Smoking can damage lung tissue and significantly increase the risk of spontaneous pneumothorax. People who smoke should consider quitting and can seek professional support if needed.
People with chronic lung diseases should follow their treatment plans carefully. Conditions such as chronic obstructive pulmonary disease, asthma, and other lung disorders can increase the risk of pneumothorax. Regular medical care can help control these conditions and maintain better lung health.
Avoiding unnecessary chest injuries is also important. Appropriate protective equipment should be used during sports, work, or other activities where there is a risk of chest trauma. Seat belts should always be worn in vehicles.
People who have previously experienced pneumothorax should discuss prevention of recurrence with their doctor. A previous pneumothorax increases the risk of having another episode. Depending on the circumstances, doctors may recommend additional treatment, including surgery, for people with repeated episodes or persistent air leaks.
Patients should follow medical advice about air travel and scuba diving after pneumothorax. Air pressure changes can be dangerous if a pneumothorax has not completely resolved. A doctor should confirm that the lung has fully expanded before returning to activities involving significant pressure changes.
Maintaining good general lung health is also helpful. Regular physical activity, a balanced diet, avoiding tobacco smoke, and protecting yourself from respiratory infections can support overall health. People with existing lung conditions should receive appropriate vaccinations and medical care according to professional recommendations.
It is important to recognize symptoms early. Sudden sharp chest pain and shortness of breath should not be ignored, particularly in someone who has previously experienced pneumothorax. Prompt medical assessment can reduce the risk of serious complications.
People who have been treated for pneumothorax should attend follow-up appointments and complete recommended chest imaging. Follow-up helps doctors confirm that the lung has fully expanded and that there is no continuing air leak.
There is no guaranteed way to prevent every pneumothorax, but avoiding smoking, managing lung diseases, preventing chest injuries, following medical advice, and receiving appropriate follow-up care can reduce risk and help protect lung health.
A sudden severe breathing problem, chest pain, bluish lips or skin, extreme weakness, confusion, or loss of consciousness requires emergency medical attention because these symptoms may indicate a serious or life-threatening pneumothorax.
