J98.2: Interstitial emphysema

We have 2 lungs. Various organs lie between the lungs, such as the heart, trachea (windpipe) and oesophagus (gullet). These organs are surrounded by connective tissue.

You need lungs to breath. When you breathe in, the air with the oxygen passes through the airways to the lungs. The respiratory tract ends in the air sacs in the lungs. Oxygen passes into the blood in the pulmonary alveoli (air sacs). The pulmonary alveoli and the airways are surrounded by supportive tissue. This supportive tissue consists of connective tissue.

In your case, air sacs have been damaged. As a result, air has gotten into the connective tissue in the lungs or connective tissue between the lungs. This can occur when the pressure in the airways in the lungs rises very sharply. This may be caused for instance by artificial respiration at high pressure. Another possible cause is coughing after an object has been swallowed.
