Oximetry Chart guidance

[trance]

I am new to using this Oximeter and would like to share last night's results. Does this look fairly normal or is there work to do?  (Note: I will lower the pressure a bit tonight to get rid of some of the CA's. I had raised it to 7 a few nights ago due to nasal blockage.) Thank you.

I'm not a doctor, nor do I play one on the internet.  But to the lay observer, a 95% SpO2 rate of 97 looks jolly good.

Those drop events are a puzzle, though. First, you may want to rule out your pulse oximeter simply losing contact. Otherwise, see if they sync up with OA or hypopnea events, or even CAs. That doesn't doesn't appear to be the case, though.

Try a few more nights and look at your results again.

trance, I'm less qualified than Sheepish to give medical or therapy advice.  However, I am quite competent at cursing the [filthyword] CMS50F firmware and software.  I had to go back to April to find SpO2 in my SH charts (I'm satisfied my O² concentrator is doing the job of keeping me oxygenated) to find charts with O².  I found some charts with Drops as low as 20 but must were between 50 and 100.  One was 139 (attaching a screenshot) and seemed to have recorded okay.  Another was 169 and is an example of problem recordings that I often get (attaching a screenshot).

I don't know if the Drops are significant of anything; I do trust the O² recording only because I've verified it with other devices, including ResMed's horribly expensive oximeter.

I don't record oximetry, but can you guys format the Y-Axis on the SpO2 and narrow the range from 70 to 100. I would think that would really help the resolution.

Thank you Sheepish and Shaun... I didn't think these events could be as dire as they looked. I feel a little short of breath, but nothing like these charts show. When I imported last night's data into SH, I ended up with 100+ hours and 1000+ events. I've only used the Oximeter a few hours total.   Well, here is the strip chart from SpO2 Assistant with the range SleepRider suggested. (I think it looks quite accurate.)

Good zoom on the Y-axis, much clearer.

See that dotted red line at about the 88% O2 (how do I get this forum to let me paste in a subscript 2?) saturation level? That's what you want to avoid dipping below, generally.

You're well above that.

(Here is a workaround to get a subscript for O2... I reduced the font size from 3 to 2.)

Thanks. Here is a workaround (?)  for a subscript in O2. (I reduced the font size from 3 to 2.)

[ShaunBlake]

... O2 (how do I get this forum to let me paste in a subscript 2?) ...

Here's  a superscript, which is the preferable (proper) way to abbreviate oxygen: O²
(The acceptable alternative is O2; O₂ is not correct.


If on Windoz, hold down ALT key and type 0178 on the numeric keypad; if on Mac, you can do it in Pages and paste your result in your post.

Hope that helps!

Alternatively, you can use the forum's superscript or subscript code.

The code would be:

Code:

Example[sup]1[/sup] <---- superscript code

That would render as:

Example¹ <---- superscript number 1


For subscript, the code would be:

Code:

Example[sub]1[/sub] <---- subscript code

That would render as:

Example₁ <---- subscript code


You can also mess around with the font size if you'd like to further reduce the relative size of the superscript or subscript character.
