Chronic lung disease (CLD) is sometimes known by its histological finding – bronchopulmonary dysplasia (BPD).
There are a variety of definitions, but the most commonly accepted is:
Treatment with O2 for ≥ 28 days AND still in O2 at ≥ 36/40 CGA.
However, the reference below describes “mild CLD” as treatment with O2 for ≥ 28 days and in air at ≥ 36/40 CGA, and some babies born at term also develop CLD after severe initial lung disease.
