My daughter has a genetic disorder (18p minus syndrome) and recently had a sleep study. I attend a recent conference for 18th chromosome syndrome and a pediatric sleep specialist said that many sleep studies are being scored with adult criteria. I received a copy of my daughter sleep study in the mail and was curious if pediatric or adult criteria was used.
Total Recording: 574 min.
Total Sleep Time: 360 min.
Sleep Efficiency: 63%
Sleep onset latency: 14 min.
REM latency: 390 min.
197 min. spent in wakefulness after sleep onset
Stage 1 sleep 1.5% of sleep time
Stage 2 sleep 44.6
Slow Wave Sleep: 36.9
REM Sleep: 16.9
Patient may have had rare respiratory paradox, and one episode where she was arching her neck while is deucubitus position.
Total 8 spontaneous arousal, 5 central apneas, 1 hypopnea, and 39 respiratory effort related arousals.
Apnea/Hypopnea index was very mildly elevated at less than 1 with the respiratory disturbance index at 7.5
Central Apnea Index within normal at less than 1
Two periodic breathing episodes totally 1 minute 2 sec.
All central episodes occurred during REM sleep, not an obvious positional component
CO2 7.5 total sleep with values greater than 50 torr
0.3% total sleep time with oxygen sat. less than 89%
Majority of hypoxemic episodes occurred during central apneas in REM sleep & were very mild
Sinus rhythm during examination was expected & minimal & maximal heart rate of 52 & 112, without evidence of bradycardic.
Sleep architecture was remarkable for a decrement of REM sleep. No obvious seizure activity notes, but full seizure EEG montage was not utilized.
