NO is used for infants with conditions such as meconium aspiration syndrome,pneumonia,sepsis,and congenital diaphragmatic hernia.Most infants with these disorders do have mature lungs.NO is not oxygen.Inhaled NO is beneficial for infants with meconium aspiration syndrome,but it does not work by removing debris.Inhaled NO is a significant treatment for infants with persistent pulmonary hypertension,pulmonary vasoconstriction,and subsequent acidosis and severe hypoxia.When inhaled into the lungs,it causes smooth muscle relaxation and reduction of pulmonary vasoconstriction and subsequent pulmonary hypertension.
