Daytime nap studies are specific, but not sensitive, in detecting sleep apnea. This is because obstructive events are more likely to occur during rapid eye movement (REM) sleep than during other sleep stages, and very little (if any) REM sleep occurs during daytime naps in noninfants. Therefore, children with symptoms of obstructive sleep apnea who have normal nap study findings must undergo nocturnal polysomnography to exclude the diagnosis. Sleep studies should be performed without sedation.
