Transient tachypnea of the newborn 

Transient tachypnea of the newborn (TTN, TTNB, or "transitory tachypnea of newborn") is a respiratory problem that can be seen in the newborn shortly afterdelivery. Amongst causes of respiratory distress in term neonates, it is the most common.[1][2] 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. It might be prevented by delivering on hands and knees and allowing 2 minutes to pass between the delivery of the head and body, during which time the fluid in the lungs is forced out by the pressure on the fetal chest. (3) It is most often seen in 35+ week gestation babies who are delivered by caesarian section withoutlabor. Usually, this condition resolves over 24–48 hours. Treatment is supportive and may include supplemental oxygen and antibiotics. The chest X-Ray shows hyperinflation of the lungs including prominent pulmonary vascular markings, flattening of the diaphragm, and fluid in the horizontal fissure of the right lung.
