The most important intervention to be made by the nurse if she suspects that an infant may have a tracheoesophageal fistula or esophageal atresia is to administer oxygen needed based on the infant's oxygen saturation level or arterial gas blood result. She should maintain an open pathway for the air to freely come inside.
