How Oxygen Toxicity Disrupts Lung Development in Preterm Infants
Why can life-saving oxygen contribute to BPD? Follow the mechanism from reactive oxygen species to inflammatory injury, impaired alveolar septation, and altered pulmonary vascular growth—while keeping oxygen toxicity in its proper, multifactorial context.
Severe BPD on Pediatrics Boards: Counsel About Risk Without Overclaiming
Practice describing the long-term risks linked to severe BPD without turning population-level associations into predictions about one child.
When a 28-Week Preterm Infant Needs More Oxygen: Is the PDA Really Driving the Deterioration?
At 21 days, a 28-week infant with rising oxygen needs, a continuous murmur, and pulmonary congestion may have a hemodynamically important PDA—but the murmur is not the diagnosis. This case discussion shows how to separate ductal pulmonary overcirculation from sepsis, evolving lung disease, and pulmonary hypertension, then use echocardiography together with the clinical picture to judge whether closure is likely to help.
