Pulmonary Function
Pulmonary function has been investigated extensively in patients with BPD at various ages, and the findings have led to a better understanding of the nature of the disease2,3,19.BPD prognosis has improved considerably over the last decades owing to advances in neonatal care, and infants who develop “new” BPD are much more immature7. Therefore, long-term pulmonary function is expected to be different between patients with “new” and “classic” BPD.
