The medical term for a collapsed lung is atelectasis. Part or all of your lung can collapse due a blockage in the lung cavity that prohibits the lung from expanding as you inhale. Your lung can also collapse if there is a hole in the lung that allows air to escape. Additionally, a condition called pneumothorax, which is a buildup of air outside of the lungs, can inhibit your lungs from expanding fully. Injuries, disease, complications during surgery and smoking can all cause a collapsed lung.
Common Symptoms
According to Cedars Sinai Medical Center, if the damage to the lung is minor, there may be no symptoms at all. If there are symptoms, initially they may be general and mimic the symptoms of many other diseases. These symptoms include shortness of breath that may be mild or severe, a racing heart rate or a persistent hacking cough. These symptoms will get worse as the condition progresses.
Additional Symptoms
A collapsed lung may also cause a drop in blood pressure, pain near the lungs where the damage is located, and fast and shallow breathing. You may also develop a fever if your collapsed lung is due to an infection. Additional warning signs include extreme fatigue and pain in the shoulder, neck or abdominal area.
Severe Symptoms
If the damage to your lungs is severe, your blood may not be able to deliver enough oxygen to your body. If this occurs, your skin may develop a bluish or ashen color. You may also have chest pain or tightness especially when trying to take a deep breath. This condition can lead to life-threatening cardiac arrest and shock.
