Fig. 2: Obstructive events during sleep.
From: Obstructive sleep apnea is position dependent in young infants
Number of infants according to obstructive apnea-hypopnea index (OAHI). Red vertical lines indicate OAHI levels of 1 (zoomed figures) and 5 per hour during sleep. OAHI shifts from higher values towards lower, normal values from supine- to side-sleeping position. In supine, all infants (72) had OAHI above 1 per hour and 48 (67%) had above 5 per hour of sleep. In the side-sleeping position, 51 (71%) infants had OAHI above 1 per hour and 30 (42%) had above 5 per hour during sleep.
