Failure of any of a complex series of cardiovascular and pulmonary modifications that help the neonate transition to extrauterine life can manifest as neonatal respiratory distress. Clinical features of a newborn in respiratory distress include tachypnea of more than 60 breaths per minute; cyanosis; expiratory grunting; intercostal, subcostal, or supraclavicular retractions; and nasal flaring. Although the causes of respiratory distress are numerous, this chapter focuses on a relatively common cause of respiratory distress known as transient tachypnea of the newborn (TTN) and the identification of a more serious condition, persistent pulmonary hypertension of the newborn (PPHN).
