What do normal Oxygen variations look like?

Hello,

 My oxygen variation charts remain in the low part of the chart but zig zag all over the place, sometimes nearly touching the bottom line.. is thus normal? What does good look like?

Hi @LEWard.  Good question.  According to Fitbit, variation is normal. Good would be variation that is mostly in the low range.  Looking at my graphs over the past week, I seem to pop into the high range a few minutes most nights (I guess its a few minutes, the chart is not all that detailed on the time range). I don't think there is any absolute super good or super bad graph, but it can be interesting to think back on what might be going when you have more than normal (for you) high variation in a record. Did you sleep well that night or poorly. Change bed times, eat late, lots of exercise? 

The one from last night has a longish period (for me at least) in the high range. Maybe because I had three drinks yesterday?
