The infant is usually near term, term, or large and premature, and shortly after delivery has tachypnea (>60 breaths/min and can be up to 100–120 breaths/min) or within the first 6 hours of delivery. The infant may also have grunting, nasal flaring, rib retraction, and varying degrees of cyanosis (uncommon, usually mild and responsive to oxygen). The infant often appears to have the classic “barrel chest” secondary to the increased anteroposterior diameter (hyperinflation). One can hear crackles on auscultation. The liver and spleen are palpable because of the hyperinflation. There are usually no signs of sepsis. Some infants may have edema and a mild ileus on physical examination. One can also see tachycardia with usually a normal blood pressure. Neurologically normal and no signs of sepsis. Some clinicians differentiate transitional delay, transient tachypnea, and prolonged tachypnea.
