Function of surfactant

Reduce surface tension at air-liquid interface of alveolar surface

10

2 treatments for RDS

1. Spray lungs with artificial surfactant
2. Give mom corticosteroids a few days before delivery

Tracheoesophogeal fistula

Abnormal connection between the trachea and esophagus

13

Respiratory distress syndrome

Lack adequate surfactant
Distress to take breath
Destroys integrity of the surface of the lining of the lung
