A collapsed lung may also cause the chest to feel tight or the skin to look bluish, explains MedlinePlus. A health care provider can listen to the patient's breathing with a stethoscope to help determine if the lung is collapsed. A chest X-ray or arterial blood gas test may also be used to diagnose the lung's condition.

When the collapsed lung is severe, symptoms begin quickly and may become life-threatening, according to WebMD. Symptoms may also grow worse with changes in the altitude.

A collapsed lung is generally caused by a chest injury, explains WebMD. It may also occur due to a medical condition, such as asthma, pneumonia, chronic obstructive pulmonary disease or cystic fibrosis. A patient without underlying medical conditions may develop a collapsed lung through spontaneous pneumothorax, caused by the rupturing of an air-filled blister on the lung.

Individuals more at risk for a collapsed lung are those who smoke or are tall and thin, according to MedlinePlus. An individual who has had a collapsed lung should stop smoking to decrease the likelihood of developing another collapsed lung.
