I don't have an oximeter that you can wear at night and upload data from. It's just one of the cheap ones that clamp down on your finger. I did find my oxygen test from when I was first on cpap. I know that I did one on bipap too and the results were pretty much the same. What I was told is that my average is 91% and as long as it's above 90% it's normal.

Last night I tried to go down to 16/12 but couldn't fall asleep so I switched back to the higher pressures. I'm going to try and lower them slowly.

Here is that initial oxygen test.

Isn't the ESS supposed to be a survey where they ask me questions? They never did that. They just posted that score with the sleep test.

I'm lying now?

Oh stop it.

The guy who wrote the report is lying.

If you plan on DWing you absolutely need one.

Well then they both suck because you had an AHI 30. Sure wish we had the CPAP SleepHQ.

You need to put an asterisk there because it's definitely not normal.

Except...

If you happen to be living in Colorado Springs.

Oxygen starts behaving a little funnily at ~90% saturation. Small changes in oxygen levels (PaO2) result in much larger changes in O2 saturation than say at 95%.

In addition, breathing is normally controlled by PCO2 (and pH). However, once you hit PaO2 60mmHg or ~90% O2 saturation, breathing is heavily dependent on pO2 as the primary driving force. Consequently, one wonders if the respiratory events are largely central-oriented.

Talking about DWing101, the general rule is increase EPAP until apneas disappear, then increase IPAP (or PS, tomatoes) until hypopneas and FLs disappear. Having that early data would have been helpful to

figure out exactly what you're trying to fix before you try to fix it.

That said, seems to me EPAP is way too high.

That's what I meant. I was told that 91% is normal for Colorado Springs.

When I get home later, I can see if I can get into my old computer. It might have the data from those early days.

I know.

That was for the other kids.

Managed to get into my old computer. The CPAP data is still on OSCAR. Here's the overview.

Well, if you feel like it, load some first week of August stuff into SleepHQ.

Is there a way to get the data from OSCAR to sleephq? I don't have the original SD card and when I try to export from OSCAR, it's just a CSV text file.

Yup.

Create a new account. Might need a new email. Load the same files requested in the info box. They are probably in Explorer>Documents>OSCAR_Data>Profiles>(name)>MachineID>Backup.

Alright, thank you! I got it.

This is the night that your oximetry showed 174 desaturations and an ODI (which extrapolates to an AHI) of 31.6:

If that's the norm, does that indicate that I would need supplemental oxygen? I'm so confused as to why the doctor wasn't concerned at all.

Can you recommend an affordable oximeter that would work with OSCAR?

Well, he's not exactly "not concerned all". A keen forum observer posted earlier that

...the physician noted "Sleep Related Hypoxemia". That's different from OSA desaturations.

In re: the need for supplemental oxygen that same poster said you should get a

PFT

And y'know, that same guy also said

IMO you need to stop DWing and figure out exactly what you're trying to fix before you try to fix it.

so he seems PF smart.

Anyway...

The Colorado Springs elevation is definitely a confounder but IMO for a 36 year old the baseline drops too low during night. Indeed, since the Watch-PAT algorithm doesn't actually measure breathing you might not have OSA at all.

So more testing-- real NPSG, PFT (make sure they do a Complete PFT with diffusion, not simple spirometry), consider testing for a PFO, and plus careful review why you "feel bad" cause your sleep doesn't look train-wreck bad and might really be fatigue from one of the million things that cause that. Oh WTF get an MSLT to objectively quantify the level of daytime sleepiness.

I use Contec CMS50F https://www.amazon.com/dp/B00LN4LCMC?re ... in_title_1

Oh OMT: lose some weight.
