bronchopulmonary dysplasia
Pronunciation: BRON-ko-PUL-mo-nair-ee dis-PLAY-zhuh
A chronic lung disease that affects premature infants who have received prolonged mechanical ventilation and oxygen therapy.
Full Definition
Bronchopulmonary dysplasia (BPD) is a form of chronic lung disease that primarily affects premature babies born before 32 weeks of gestation. It develops as a result of lung immaturity combined with factors such as mechanical ventilation, oxygen toxicity, infection, and inflammation. Infants with BPD require ongoing respiratory support and may have long-term breathing difficulties. The condition is diagnosed when an infant still requires supplemental oxygen at 28 days of life or at 36 weeks postmenstrual age.
Usage
Usage note: Often abbreviated as BPD in clinical documentation; avoid confusion with bipolar disorder or borderline personality disorder.
