*Chronic lung disease that develops in premature infants who require prolonged mechanical ventilation and/or supplementary oxygen, usually due to [[respiratory distress syndrome]]
*Develops within first 4 weeks of life while infant still in NICU
*Typically lung function improves with time, but many require long term O2 supplementation or other therapy

==Clinical Features==
*May be asymptomatic until something (e.g. infection, respiratory irritant) triggers decompensation
*[[SOB]]
*[[Hypoxia]]
*Increased respiratory secretions
*Wheezing, crackles
*+/- [[pulmonary hypertension]]
*Poor feeding

==Differential Diagnosis==
{{Pediatric wheezing DDX}}
{{Pediatric SOB DDX}}

==Evaluation==
[[File:CXR - Bronchopulmonary dysplasia.jpg|thumb|[[CXR]] of a patient with  of bronchopulmonary dysplasia.]]
*Typically not an ED diagnosis
*Evaluate for precipitants of decompensation (e.g. infectious workup etc.)
*[[CXR]]
**Hyperinflation, low diaphragm, atelectasis, cystic changes

==Management==
*Escalate chronic home therapies 
*Supplementary O2 and/or positive pressure ventilation as needed
*[[Bronchodilators]]
*[[Diuretics]] if euvolemic-hypervolemic
*Treat decompensated [[pulmonary hypertension]]

==Disposition==
*Low threshold to admit for acute respiratory symptoms
