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.
This results in vasodilation, or widening of the blood vessels, and an increase in blood flow. Nitric oxide helps the blood vessels maintain their flexibility so that the blood can flow unrestricted throughout the body, including the penis. As mentioned, L-arginine is the substance the body uses to create nitric oxide.
