Learn About Collapsed Lung

What is the definition of Collapsed Lung?

A collapsed lung occurs when air escapes from the lung. The air then fills the space outside of the lung between the lung and chest wall. This buildup of air puts pressure on the lung, so it cannot expand as much as it normally does when you take a breath.

The medical name of this condition is pneumothorax.

Air around the lung; Air outside the lung; Pneumothorax dropped lung; Spontaneous pneumothorax

What are the causes of Collapsed Lung?

Collapsed lung can be caused by an injury to the lung. Injuries can include a gunshot or knife wound to the chest, rib fracture, or certain medical procedures.

In some cases, a collapsed lung is caused by air blisters (blebs) that break open, sending air into the space around the lung. This can result from air pressure changes such as when scuba diving or traveling to a high altitude.

Tall, thin people and smokers are more at risk for a collapsed lung.

Lung diseases can also increase the chance of getting a collapsed lung. These include:

  • Asthma
  • Chronic obstructive pulmonary disease (COPD)
  • Cystic fibrosis
  • Tuberculosis
  • Whooping cough

In some cases, a collapsed lung occurs without any cause. This is called a spontaneous collapsed lung.

What are the symptoms of Collapsed Lung?

Common symptoms of a collapsed lung include:

  • Sharp chest or shoulder pain, made worse by a deep breath or a cough
  • Shortness of breath
  • Nasal flaring (from shortness of breath)

A larger pneumothorax causes more severe symptoms, including:

  • Bluish color of the skin due to lack of oxygen
  • Chest tightness
  • Lightheadedness and near fainting
  • Easy fatigue
  • Abnormal breathing patterns or increased effort of breathing
  • Rapid heart rate
  • Shock and collapse

What are the current treatments for Collapsed Lung?

A small pneumothorax may go away on its own over time. You may only need oxygen treatment and rest.

The provider may use a needle to allow the air to escape from around the lung so it can expand more fully. You may be allowed to go home if you live near the hospital.

If you have a large pneumothorax, a chest tube will be placed between the ribs into the space around the lungs to help drain the air and allow the lung to re-expand. The chest tube may be left in place for several days and you may need to stay in the hospital. If a small chest tube or flutter valve is used, you may be able to go home. You will need to return to the hospital to have the tube or valve removed.

Some people with a collapsed lung need extra oxygen.

Lung surgery may be needed to treat collapsed lung or to prevent future episodes. The area where the leak occurred may be repaired. Sometimes, a special chemical is placed into the area of the collapsed lung. This chemical causes a scar to form. This procedure is called pleurodesis.

What is the outlook (prognosis) for Collapsed Lung?

If you have a collapsed lung, you are more likely to have another one in the future if you:

  • Are tall and thin
  • Continue to smoke
  • Have had two collapsed lung episodes in the past

How well you do after having a collapsed lung depends on what caused it.

What are the possible complications of Collapsed Lung?

Complications may include any of the following:

  • Another collapsed lung in the future
  • Shock, if there are serious injuries or infection, severe inflammation, or fluid in the lung develops
When should I contact a medical professional for Collapsed Lung?

Call your provider if you have symptoms of a collapsed lung, especially if you have had one before.

How do I prevent Collapsed Lung?

There is no known way to prevent a collapsed lung. Following standard procedure can reduce the risk of a pneumothorax when scuba diving. You can decrease your risk by not smoking.

Aortic rupture - chest X-ray
Pneumothorax - chest X-ray
Respiratory system
Chest tube insertion - series - Pleural cavity

Characterization of the Pathogenesis of Lymphangioleiomyomatosis (LAM)

Summary: Pulmonary lymphangioleiomyomatosis (LAM) is a destructive lung disease typically affecting women of childbearing age. Currently, there is no effective therapy for the disease and the prognosis is poor. This study is designed to determine the disease processes involved at the level of cells and molecules, in order to develop more effective therapy. Researchers intend to identify the proteins and ge...

Pleural Manometry for the Characterization of Spontaneous and Tension Pneumothorax

Summary: Intrapleural pressures have been shown to be a useful clinical predictor in pleural effusions, however it's utility has not been described in pneumothorax. Data on intrapleural pressures in pneumothorax are limited. Furthermore, the pleural pressure in tension pneumothorax is theorized to be greater than atmospheric pressure, though this has never been verified. Pneumothorax is primarily treated w...
