How do I interpret the blood oxygen variation graph?

[Emmy_M]

Good morning,

I use a Charge 3 and recently noticed the addition of a blood oxygen variation graph in my sleep data. I've been googling a bit but am unsure how to interpret it. Can someone help?

Unfortunately, I'm unable to include a picture, but I'll try to explain as best I can.

The x-axis is clearly for time, but what about the y-axis? There's a line about halfway up where labels say "large" above it and "small" below it (my translation; I use the app in Swedish). The graph legend also states that a green line indicates small variations, while yellow marks bigger variations, so that's also pretty self-explanatory. My graph is almost entirely green every night, but it's fairly low on the chart. Does this mean my Charge 3 estimates I have a fairly low level of blood oxygen, but with small variations? The few times the graph has been yellow, it's been to form a peak rather than a trough.

Thanks in advance.

Hi Wilson,

All my graphs on the app  suddenly changed to constant high variation even the ones for the days before although before they were in normal zone.I check it every morning.

Me too!  The new graph looks like every night is a mess where as my old ones would show one high variation every few nights.

@Josipk and @SueChem that is happening to a lot of us right now. There's a discussion about it here and you may want to watch that thread for updates.

I have many nights oxygen spent record even with 6 hours sleep. Faulty I agree.

I've noticed with mine it's most

 

always in the low green area but a few times it has a flatline included. What does the flatline mean??

I have Inspire 3 and I have oxygen data so you are incorrect

I have Inspire 3 and I have the oxygen data

Wow, yours doesn't seem to vary all that much. 

I am trying to see if mine means I should be looking into sleep apnea.

How do you view your percentage for the oxygen variation? I can only see the graphs but no percentages..
