A Real-world Study of Nitric Oxide Generator and Delivery System

This study is tracking real-world use of an inhaled nitric oxide delivery device in newborns with high blood pressure in the lungs (pulmonary hypertension). Nitric oxide gas is inhaled to help relax and open blood vessels in the lungs, making it easier for babies to breathe. **You may be eligible if...** - Your baby is admitted to a neonatal unit - Your baby has been diagnosed with pulmonary hypertension (high blood pressure in the lungs) - The clinical team has decided inhaled nitric oxide is appropriate for your baby - Your baby requires breathing support and has documented low oxygen levels - You (as parent or legal guardian) can give informed consent **You may NOT be eligible if...** - There are known medical reasons why nitric oxide would be unsafe for your baby - Your baby is also being treated with other pulmonary vasodilators, surfactant therapy, or ECMO (a type of heart-lung bypass) Talk to your doctor to see if this trial is right for you.
