Hypoxic episodes are troublesome components of bronchopulmonary dysplasia (BPD) in preterm infants. Immature respiratory control seems to be the major contributor, superimposed on abnormal respiratory function. Relatively short respiratory pauses may precipitate desaturation and bradycardia. This population is predisposed to pulmonary hypertension; it is likely that pulmonary vasoconstriction also plays a role. The natural history has been well-characterized in the preterm population at risk for BPD; however, the consequences are less clear. Proposed associations of intermittent hypoxia include retinopathy of prematurity, sleep disordered breathing, and neurodevelopmental delay. Future study should address whether these associations are causal relationships.

Intermittent hypoxemia (IH) events are common during early postnatal life, particularly in preterm infants. These events have been associated with multiple morbidities, including retinopathy of prematurity, sleep disordered breathing, neurodevelopmental impairment, and mortality. The relationship between IH and poor outcomes may depend on the patterns (frequency, duration, and timing) of the IH events. Current treatment modalities used in the clinical setting have been only partially successful in reducing the incidence of apnea and accompanying IH, but the risks and benefits of more aggressive interventions should include knowledge of the relationship between IH and morbidity.
