What is nitric oxide? Nitric oxide is a gas that is inhaled. It works by relaxing smooth muscle to widen (dilate) blood vessels, especially in the lungs. Nitric oxide is used together with a breathing machine (ventilator) to treat respiratory failure in premature babies. Your baby will receive this medication in a neonatal intensive care unit (NICU) or similar hospital setting.
Your blood vessels require the amino acid L-arginine for the synthesis of nitric oxide, since L-arginine is its precursor in your body. By helping to regulate your blood pressure, nitric oxide enhances blood flow. Nitric oxide signals the smooth muscle cells in your blood vessels to relax so that your vessels dilate and your blood flows more freely, which helps your arteries stay free of plaque.
