What causes bronchopulmonary dysplasia?

When your baby is born early, sometimes they need help breathing because their lungs are underdeveloped. This means your baby may need to be on a ventilator. The ventilator provides oxygen and pressure to help their lungs expand and support your baby’s breathing. However, delivering pressure to their air sacs can also harm their lungs in the process.
