Abnormal Sleep Architecture

Can anyone explain what this means? In reviewing my sleep study results, the term "Abnormal Sleep Architecture" was noted in my results. along with severe sleep apnea and severe oxygen desaturation. However, since(I guess) the study was made for the professionals and not the patient, this term was not defined nor explained.

Abnormal sleep architecture is the order in which you go through the sleep stages. Normal would be stages 1, 2, 3, Rem, etc. You are apparently not going through the normal stages (join the club...I'm doubting that very many on this board actually go through all the normal stages of sleep without our CPAP's).

So all in all, you seem to have had a "normal" abnormal sleep study for someone with severe sleep apnea.

PS: I'm not a medical professional---I just happened to know what this meant.

Hi Sarkel!

I copied a few histograms (graphs) of normal and abnormal sleep architecture, take a look and see if this helps:

Dave,

That was really interesting. Now I'm going to pull out the graphs from my before and after titration studies and see if I can figure mine out. Thanks. You are full of great information, and so helpful, too .

Sarkel,

My first study, before titration, said that my sleep architecture was being significantly fragmented by PLMDs, which completely disappeared on the titration study. Go figure...
