What is missing from the lungs of newborn babies with infant respiratory distress syndrome?

Neonatal RDS occurs in infants whose lungs have not yet fully developed. The disease is mainly caused by a lack of a slippery substance in the lungs called surfactant. This substance helps the lungs fill with air and keeps the air sacs from deflating. Surfactant is present when the lungs are fully developed.

Any remaining fluid is then coughed out or slowly absorbed through the bloodstream and lymphatic system.

What is the treatment of TTN?

Medical care of transient tachypnea of the newborn (TTN) is supportive. As the retained lung fluid is absorbed by the infant’s lymphatic system, the pulmonary status improves. Supportive care includes intravenous fluids and gavage feedings until the respiratory rate has decreased enough to allow oral feedings.

What happens when baby is born with fluid in lungs?

Wet lungs (transient tachypnea) is a respiratory disorder in a newborn. Soon after birth, your newborn might have a weak cry and fast, labored breathing. It’s caused by extra amniotic fluid in the lungs.
