Is it possible to officially have obstructive sleep apnea without decreased oxygen sats?
In case you want the details, I had a portable sleep study done at home (the proper ones have a 2 year wait list, which I'm on), and got the results today:
REM (Norm: 20-25%) 14,8%
S1 (Norm: 5%) 1,6%
S2 (Norm: 45-50%) 36,4%
S3 (Norm: 5-15%) 16%
S4 (Norm: 10-15%) 18.1%
This part was apparently not so abnormal. BUT I had 302 obstructive apneas in 520 minutes of sleep time (Index: 33.7)! This sounds as if it could be part of the reason why I'm always so exhausted, however my oxygen sats were 95% on average, and 90% at the lowest. I was sent the test results, and the result is (in translation): "Normal sleep structure, High number of apneas, but no decrease in oxygen saturation."
Have any of you had similar results, or know what this means? Can you officially have obsructive sleep apnea without decreased oxygen sats? Due to other medical issues, I can only sleep on my back. I always sleep with my head to the side (as far as is possible, without causing neck problems) because I otherwise feel my airway collapsing. I also did this during the test.
Thoughts? Advice?! Would CPAP treatment still help?
Thanks in advance!
