Collapsed Lung Symptoms
8. Changes in Breathing Sounds
There is asymmetric lung expansion in most cases of pneumothorax. It is also common to have diminished or distant-sounding breath sounds on the affected side.
This occurs due to the decreased air entry to the lung. When the doctor listens to the sounds, the difference in breathing sounds will usually be apparent. Wheezes and crackles may also be present.
