[rosebee]

he sleep study I had Tuesday night said I had no apneas orhyponeas.  Can anyone help me figure out what the rest of these numbersmean?

Technologist Comments: "Increased sleep fragmentation and WASO seenmid-study.  No significatn obstructive events or desaturations.  Verymild snore at times.  RERA's scored.  Sinus rhythm with baselinetachcardia (low 90's)."




So according to this my husband was imagining those times he woke me up for not breathing &/or choking?

From what I've read, I know I'm getting only half of the REM sleep one's supposed to get (normal range for adults is 20 to 25% of sleep time). I had no stage 4 sleep, but evidently that's not uncommon for a sleep study (wires, strange place, strange bed, etc).

I'm REALLY curious to see what the Sleep Center Dr has to say about these results... and especially if they can do anything about all those different arousals that kept pulling me out of sleep all night long. I'm also definitely going to ask him why the study didn't record any apnea events when MrBee has definitely seen me have them.
