What condition is characterized by chronic lung disease due to the combination of oxygen therapy and intermittent mandatory ventilation in preterm infants?

Bronchopulmonary dysplasia (BPD) is a chronic lung disease that commonly occurs in preterm infants who have received oxygen therapy and mechanical ventilation. This condition arises because the infants' lungs are often immature and have not developed the surfactant necessary for proper lung function. The use of oxygen and mechanical ventilation can lead to injury of the lung tissue, inflammation, and further complications, contributing to the long-term lung disease.

In preterm infants, the developmental stage of their lungs at birth affects their ability to tolerate oxygen and support their breathing adequately. When these infants require assistance with ventilation, they are at risk for a cascade of events that may result in BPD, including barotrauma from high airway pressures and oxygen toxicity from prolonged oxygen therapy. As a chronic condition, BPD often requires ongoing respiratory support and can lead to a range of secondary complications and longer hospital stays.

In contrast, neonatal respiratory distress syndrome primarily results from surfactant deficiency, while pulmonary hypertension involves elevated blood pressure in the pulmonary arteries unrelated directly to the mechanical ventilation and oxygen therapy practices. Infantile apnea consists of intermittent cessation of breathing, which can occur in various contexts and not specifically linked to the chronic lung injury seen in BPD.
