Two layers of thin membrane cover your lungs. The two membranes normally touch each other. But sometimes the space between the membranes, called the pleural space, fills up with air or fluid.
Air in the pleural space is called pneumothorax. Fluid in the pleural space is called pleural effusion.
What is a pneumothorax?
What causes a pneumothorax?
A pneumothorax is caused by a tear or injury to the membrane around your lung. This can happen from:
-
Weakening in a small area of your lung (this most often happens in tall men under 40 who smoke)
-
A long-term lung problem such as COPD, cystic fibrosis, asthma, or tuberculosis
-
Chest injury or surgery (traumatic pneumothorax)
-
Pressure damage from a breathing machine
What are the symptoms of a pneumothorax?
Symptoms of a pneumothorax depend on how much air enters the pleural space and how much of your lung collapses. Symptoms may happen suddenly or slowly. You may have:
-
Shortness of breath
-
Chest pain
-
Sometimes, pain in your shoulder
-
If a large pneumothorax happens suddenly, sometimes shock and cardiac arrest
Usually, your body reabsorbs the air and the pneumothorax goes away over 2 to 4 weeks.
How can doctors tell if I have a pneumothorax?
To tell if you have a pneumothorax, doctors listen to your breathing with a stethoscope. They’ll also do a chest x-ray or ultrasound.
How do doctors treat a pneumothorax?
Treatment depends on how large your pneumothorax is.
If there's only a small pneumothorax, doctors may:
For a larger pneumothorax, or if you're having trouble breathing, doctors will:
Usually the chest tube is connected to a vacuum device to pull the air out. You'll have the chest tube for a couple days until your lung heals.
