Pneumothorax, Pneumomediastinum and Pulmonary Interstitial Emphysema

Normally the air that we breathe goes down the trachea (windpipe) , which branches off into 2 bronchi , and then branches further in each lung into numerous bronchioli . At the end of each bronchiole are the alveoli , air sacs where oxygen is delivered to the blood and carbon dioxide is released. If the alveoli become overfilled with air, the air can break out of the air sacs and get into spaces where it should not be.
This condition is sometimes referred to as air leak and includes the following main disorders: 

  • Pneumothorax where the air is trapped inside the chest between the chest wall and the lung, the pleural space , causing the lung to collapse.
  • Pneumomediastinum where air is trapped in the middle part of the chest.
  • Pulmonary Interstitial Emphysema (PIE) where air is trapped between the tiny air sacs, encircling the smallest blood vessels and bronchi.

Although air leak can happen in any baby, it is more common if a neonate has an underlying lung disease, if the neonate needs CPAP or mechanical ventilation, if the infant is premature . Symptoms and treatment largely depend on the type and severity of the air leak present.
