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.
Nitric oxide signals the smooth muscle cells in your blood vessels to relax, so that your vessels dilate and your blood flows more freely. This helps your arteries stay free of plaque. When you have inadequate nitric oxide, your risk for coronary artery disease increases.
