Side & front sleep are the usual for me at home, during the study however front sleep was impossible and i could only comfortably lie on one side without feeling restricted. Looking at the graph showing Sleep Stage / Arousals / Position. I have no arousals during stage's 3 & 4 and seem to struggle to get out of stage 2. I also have 4 smallish block of REM sleep (say 15min/10/10/12 approx.) is REM usually a single block of time or broken up into smaller periods?

Hypopneas have been recorded in WAKE periods, dumb question but, wouldn't i know these were taking place?

Big thanks to everyone - you have been so helpfull.

Pretty much the rule due the inherent stability of SWS.

REM usually occurs at 90 minute intervals, increasing in duration as the night goes on, totalling about 20% of TST.  This can be altered by sleep deprivation, certain medications, diseases such as narcolepsy and/or severe sleep fragmentation caused by such things as OSA.

Scoring the hypopneas during Wake was dumb.
