Surfactant therapy

Medical administration of exogenous surfactant

Surfactant therapy is the medical administration of exogenous surfactant. Surfactants used in this manner are typically instilled directly into the trachea. When a baby comes out of the womb and the lungs are not developed yet, they require administration of surfactant in order to process oxygen and survive. This condition that the baby has is called newborn respiratory distress syndrome, and it is treatable. Surfactant coat the smallest parts of the lungs called the alveoli and helps for oxygen to go in and for carbon dioxide to go out. How surfactant does this is by not allowing the alveoli to collapse and to retain their inflated shape when the baby exhales.
