Heliox Adjunct Therapy for Neonates With Congenital Diaphragmatic Hernia.

Background: Congenital diaphragmatic hernia remains a complex disease with significant morbidity and mortality. Hypercarbia is a common derangement in this population, which often requires escalating ventilator support. By decreasing airway turbulence and enhancing CO removal, inhaled helium-oxygen mixture (heliox) has the potential to improve ventilation and thereby decrease ventilator support and its associated lung injury.
