Pulmonary disorder in newborns due to a surfactant deficiency frequently related to premature newborns. It represents the most frequent cause of respiratory failure in premature newborns (PNB) is due to surfactant deficiency. Surfactant deficiency increases the surface tension of the alveolus favoring its collapse, which causes a progressive decrease in residual functional capacity and decreased lung compliance, causing greater respiratory effort. There are alterations in ventilation-perfusion that cause hypoxemia and CO2 retention due to alveolar hypoventilation.
