Mild hypoxia at birth can usually be recovered through active treatment, but may leave sequelae if the condition is delayed. Whether or not a newborn can recover from hypoxia depends on the specific situation. If it is a mild brain injury caused by mild hypoxia, it can usually be recovered through active treatment, while severe hypoxia may leave after-effects. However, regardless of the severity, hypoxia should be relieved as soon as possible, mainly through the improvement of oxygen, prevention of cerebral edema, mild hypoxia children as long as the timely intervention, usually within 3 days can gradually recover. At the same time, the etiology of hypoxia should be identified, usually including placental abnormalities, neonatal diseases and umbilical cord blood blockage, etc., and treated symptomatically without delay.
