Chronic lung disease. High altitude flying. Your own observation of symptoms. Medical history and physical exam by a doctor. X-rays of the chest to confirm the diagnosis and determine the size of the pneumothorax.
Treatment depends on the size of the pneumothorax and the condition of the lungs.
The disorder may heal itself, but hospitalization and treatment may be necessary to remove the air. Repeated pneumothorax requiring surgery. However, if the collapse is extensive and it occurs in middle-aged or older adults whose lungs are damaged by asthma, chronic bronchitis or emphysema, it can lead to respiratory failure and critical illness. You may be more comfortable if you rest in a sitting position. If at home, monitor your blood pressure, pulse rate and respirations.
