In soft tissues, crepitus can be produced when gas is introduced into an area where it is normally not present. The term can also be used when describing the sounds produced by lung conditions such as interstitial lung diseaseâthese are also referred to as rales.
A pneumothorax (pneumo- + thorax; plural pneumothoraces) is an abnormal collection of air or gas in the pleural space that causes an uncoupling of the lung from the chest wall.Like pleural effusion (liquid buildup in that space), pneumothorax may interfere with normal breathing.he size of the pneumothorax (i.e. the volume of air in the pleural space) can be determined with a reasonable degree of accuracy by measuring the distance between the chest wall and the lung. This is relevant to treatment, as smaller pneumothoraces may be managed differently.
