Transient tachypnea of the newborn (TTN TTNB or transitory tachypnea of newborn) is a respiratory problem that can be seen in the newborn shortly after delivery. Amongst causes of respiratory distress in term neonates it is the most common. It consists of a period of rapid breathing (higher than the normal range of 40-60 times per minute). It is likely due to retained lung fluid and is most often seen in 35+ week gestation babies who are delivered by caesarian section without labor.
