Bronchopulmonary Dysplasia (BPD)
Overview
Bronchopulmonary dysplasia is a kind of chronic lung illness that occurs in premature infants who are given oxygen and positive-pressure ventilation. The pathophysiology of this illness is complicated and poorly understood; nonetheless, a variety of causes can not only harm tiny airways but also interfere with alveolarization (alveolar septation), resulting in alveolar simplicity and a reduction in total surface area for gas exchange. Injuries to the developing pulmonary microvasculature are also possible.
