BPD
Also written as: BPD — Bronchopulmonary Dysplasia
A chronic lung disease that develops in premature infants who have received mechanical ventilation and oxygen therapy, characterized by inflammation and scarring of the lungs.
Full Definition
Bronchopulmonary dysplasia (BPD) is a chronic lung disease that primarily affects premature infants, particularly those born before 32 weeks of gestation. It develops as a result of lung injury from mechanical ventilation, oxygen toxicity, inflammation, and the immature development of the lungs. BPD is characterized by impaired alveolar and vascular development, leading to long-term respiratory problems. The condition is classified as mild, moderate, or severe based on oxygen requirements at 36 weeks corrected gestational age. Infants with BPD may require prolonged respiratory support and are at increased risk for pulmonary hypertension and neurodevelopmental delays.
Usage
Usage note: In pediatrics, BPD refers to bronchopulmonary dysplasia, not bipolar disorder or borderline personality disorder.
