Infants with CDH are at risk for pulmonary hypoplasia and pulmonary hypertension and often experience hypoxemia and acidosis during neonatal transition. The standard approach to DR resuscitation is immediate UCC followed by intubation and mechanical ventilation. The goals of this strategy are to immediately recruit and aerate the lung for gas exchange and oxygenation, while simultaneously avoiding gaseous distention of the thoracic gastrointestinal contents.
