Chronic RDS can progress to which chronic lung disease?

Chronic RDS can progress to which chronic lung disease?

• A. Bronchopulmonary dysplasia
• B. Pulmonary edema
• C. Cystic fibrosis
• D. Pulmonary hypertension

Answer: (A)

Chronic RDS in preterm infants, often from surfactant deficiency and prolonged oxygen or ventilator support, can progress into bronchopulmonary dysplasia, a chronic lung disease of infancy. Bronchopulmonary dysplasia features ongoing inflammation and scar formation in the developing lungs, leading to impaired alveolar development and long-term breathing difficulties that may require continued oxygen or support. This injury results from the combination of oxygen toxicity, mechanical ventilation, and the immature lung’s vulnerability, which together disrupt normal lung growth. That’s why bronchopulmonary dysplasia is the classic chronic consequence of chronic RDS. Pulmonary edema is fluid overload, cystic fibrosis is a genetic disease with thick secretions, and while pulmonary hypertension can occur in infants with bronchopulmonary dysplasia, it is not the direct progression of chronic RDS itself.
