@Florence Sure looks like it.
Do you get headaches after a time with your sat this low?
@GeorgeG Yes. That's what made me check. I get dizzy and faint a bit too!
@Florence I get headaches when my canula slips off during the night. Yuck! thank goodness it doesn't happen often.
I bought one of those strap things and it works pretty well, but not 100%.
@Florence
Is that your blood oxygen saturation?
