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.
As mentioned earlier, nitric oxide widens blood vessels to improve circulation and reduce blood pressure. According to the Centers for Disease Control and Prevention, about 1 in 3 US adults have high blood pressure[6], so this side effect may be desirable.
