For the vast majority of cases, low blood oxygen in newborns can be cured. For example, if a newborn has pneumonia, the newborn’s blood oxygen tends to drop to varying degrees. Pneumonia in newborns is often caused by various pathogenic bacteria, and the newborn’s blood oxygen is naturally restored when the infection is controlled with the timely application of antibacterial drugs. In addition, if the newborn’s blood oxygen is low due to respiratory distress syndrome, the newborn can be treated with ventilator support or lung surface active substances, and most of the newborn’s blood oxygen can be restored to varying degrees. If the neonate has congenital heart disease, it can be treated with cardiac catheterization to correct the hypoxia.
