The data show children can suffer significant First Night Effect (FNE) on sleep (but not necessarily respiratory events)(but since we're getting rid of a lot to most of the centrals, we probably don't need to worry about that).jdr999 wrote:Are post arousal centrals more common during sleep studies? It's plausible in my mind that being connected to all those wires and being in a strange bed can account for a more restless sleep. Can that be one of the explanations for the large number of events?
However, normal Arousal Index in children looks to be <14, so 8.7 is not "a large number".
No. It's from the point of sustained sleep. REM onset in children looks like it can be a little higher than adults (130-140 minutes), but one might want to look at the Sleep Histogram to try to determine why REM is a little delayed (for instance, there's still 33.0 of Wake in the study. If he had like one ambiguous epoch of sleep to establish Sleep Onset (and since he had no NREM1 sleep, one epoch of anything would establish Sleep Onset), but then went to Wake for another ~30 minutes, perhaps the REM Clock did not start until a little later).jdr999 wrote:His sleep onset was delayed but it's possible that was due to being in a completely new environment. In the report it mentioned that his REM onset was delayed at 161 minutes. Does that mean 161 minutes *after* sleep onset or is that 161 minutes total which also includes the delayed sleep onset?
BTW, no NREM1 is a little unusual (if we're saying there's FNE, then we should be looking at 8.0% NREM1). That and the elevated SWS suggests he might be a little sleep-deprived (at least on the night of the study).
