BACKGROUND: Management of hypoxemia in newborns includes different forms of supplementary oxygen delivery. Nasal cannula is perhaps the most widely used. However, this method present some disadvantages, such as swelling and bleeding of the nasal mucosa, which can lead to obstruction of the airway and repeated episodes of hypoxemia. The use of oxygen management techniques that do not cause local damage as cephalic camera (hood) or the incubator may improve dependence of supplemental oxygen. OBJECTIVE: To determine if using oxygen in newborns by not invasive methods (incubator or cephalic camera) is associated with a reduction in the proportion of patients discharged without supplementary oxygen, when compared with that using an invasive method (nasal cannula).
