RDS| MAS|  BPD|   NEC| Tension Pneumthorax|  Pneumomediastinum| Diaphragmatic Hernia|  Esophageal Intubation


Respiratory Distress Syndrome (RDS) CXR:

Due to underlying surfactant deficiency stemming from prematurity, there is diffuse bilateral reticular granular densities
and microatelectasis.  Common descriptions include Ground glass appearance, Salt and Pepper appearance. The underlying
lung disease results in reduced lung volume.

Meconium Aspiration Syndrome: (MAS)


Due to aspiration of meconium into the trachea and airways.  Can result in a chemical pneumonitis and obstruction of peripheral airways
due to the thick meconium. This obstruction of airways can result in a ball valve effect which may result in
hyperinflation and pneumothorax.

Bronchopulmonary Dysplasia:  (BPD)


Produced by an inflammatory response due to volutrauma and high 02 concentrations.  Air cysts surrounding dense patches
(alveolar collapse, edema, fibrosis of the interstitium).  There are 4 stages of BPD.  CXR is similar to multifocal emphysema.

Necrotizing Enterocolitis: (NEC)


Results in pneumotosis (air in the wall of the bowel) and perforation.  Perforation is due to ischemic necrosis as a result of impaired
blood flow to the bowel.  Air the portal system is an ominous sign of NEC.

Tension Pneumothorax:

Results when intrapleural pressure is greater than atmospheric during expiration and often inspiration.  Caused by disruption
of visceral or parietal pleura which results in a one way valve effect.  The end result is a reduced vital capacity
and Pa02.  Can be caused by mechanical ventilation.

Pneumomediastinum:

When air dissects out of alveoli and into the anterior mediastinum.  Collections of mediastinal air are often seen surrounding the left
heart border.  Also you my see the classic "sail sign"  or air around the thymus.

Diaphragmatic Hernia:

When the abdominal contents of the infant migrate up through a hernia in the diaphragm.  These contents impede on the heart and lungs.
Do not Bag and Mask these patients due to  gastric distention.  These patients upon delivery have a flattened abdomen
and barrel chest.

Esophageal Intubation:

Results in Endotracheal tube in the stomach.   Will see large gastric bubble and  atelectatic lungs.
