Bronchopulmonary dysplasia (BPD), a form of chronic lung disease (CLD), affects most infants who are born more than 10 weeks before their due dates and weigh less than two pounds. Such babies’ lungs are now fully developed and have difficulty keeping them open to receive and process enough oxygen to keep the rest of their organs healthy.
Treatment usually involves surfactant replacement therapy, which keeps the lungs from collapsing. Continuous pressure ventilators (CPAP) may also be used.
Most infants fully recover, although some may have lifetime issues.
