Bronchopulmonary dysplasia (also called chronic lung disease) is a condition in which scar tissue or other damage develops on the lungs. The scar tissue or damage is caused by being on a ventilator (breathing machine).
While a ventilator is important for your baby to breathe properly, the extra pressure from the air can hurt his lungs. The damage can make it harder for your baby to breathe on his own even after he comes off the ventilator.
