Infants born &lt;32 weeks gestational age (GA) had repeat oximetry 1\u2010month post discharge. Oxygenation measures included the 3% and 4% desaturation (DSI 3%, DSI 4%) indices.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At discharge from the neonatal unit the median and interquartile range (IQR) for DSI 4% was 51 (31\u201074) events per hour with normal mean SpO<jats:sub>2<\/jats:sub> (median of 97.9% [97.2\u201098.8 IQR]). Episodes of IH 1 month post discharge decreased with improvements of between 42% and 57% seen for the three DSI measures.
