This is a try at my new O2 Ring pulse oximeter.  Can anyone tell me something about this report?  I understand that during sleep O2 levels will fluctuate but these dip down areas look pretty bad to me.  Are they indicating poor treatment of apnea?

The file will upload but does not appear here.  I suspect it is not the correct file type.  It is a pdf. not png.  I'm not sure why when I make a screen shot of an OSCAR report it goes to a png.  When I screen shot an O2 Insight Pro report it saves as pdf.

I used export under preview (Mac) to save the O2 ring image as a .png file but evidently it that does not work.

Finder shows the file is .png and it uploads but does not appear in the reply.

I just made a new reply and the image of the O2 report appeared. I hope this is okay for me to reply to my own reply. The image would not appear within this post.

You moved rapidly, or bumped the sensor. Look at the overall picture. A person doesn't suddenly drop and then come right back up.

Thank you.

Last night's sleep report of 5:36 time shows AHI 0.18 which is all hypopnea.  Apneas read 0.0.

I am up to pressures min 8, max 10, with no aerophagia.

95% = 9.96. 99.5% = 10.  Are these percentiles telling me I need to raise the max pressure?  I am not grasping what these numbers mean.  I read, "95% means you are at or below the pressure indicated 95% of the time."  That statement has no meaning for me.  Can someone phrase the purpose/meaning of the 95% percentile for a dummy?

What are these to percentiles telling me to do about pressure adjustment?  Nothing, or raise the max?

Hi, ejbpesca  It's hard to tell from the 95 percentile alone.  Could you post screenshots again, please?

Hi, ejbpesca  When I compare this chart with the previous one from November 2, when you had pressure set at 6.8 to 11, it looks like the machine did make use of the additional cm of pressure.  And leaks were not worse at 11 cm, at least not that night.

It also seemed to try to go higher at one point, but flow limits were also higher just at that point, so I wonder if it was positional?

In any case, it looks to me like 11 works better than 10 for you.  Does that seem right in terms of how you've felt?

If the minimum pressure setting of 8 was just as comfortable for you as 6.9, it could be preferable to use 8.  The idea is that swings in pressure can disturb sleep.  

At one point, Red recommended you try 9.6 to 12 cm.  It's not clear to me whether you need to increase to 12 cm, or if preventing chin tucking would be sufficient.  I hope the more expert commenters will chime in.  

BTW, re leaks, I noticed in reviewing your posts that you had gone through a period of weight loss.  That can affect mask fit.  If you're still at a lower weight, you might possibly need a different size mask, if you haven't already checked that.

Thank you for the advice, it is appreciated.

On O2 sleep reports.
I got one report that shows a dip in O2 from 97 to 80 thirty times in thirty minutes then back to near steady 97. Is that a false reading or possible to occur?
