RE: Need help interpreting Pulse Oximetry results
Yes! That looks a lot better than I expected. No flow limitation or issues there. What I see is a very good tidal volume and respiration rate and minute vent above average. This should be keeping you well ventilated. We can see some of the events from the pulse-ox chart correspond with events on the full-night Oscar. Your hypopnea at 01:30 shows up as a desaturation, but other dips in SpO2 at 02:10 and 02:30 are not evident in the Oscar chart. I think we can see the OA event at 05:50 produces a very deep dip just after 06:00 on the oximetry graph. The graphs are offset by about 10 minutes, so those add up. There are a number of dips in the oximetry graph that have no corresponding events or unusually low respiratory flow rate, so those may or may not be real, but there are not respiratory events to explain all of it.

I don't see significant issues with your therapy. The few OA events occur in clusters, so I think chin-tucking is an occasional problem as discussed in this wiki http://www.apneaboard.com/wiki/index.php...onal_Apnea The problem is not frequent or serious enough to merit a soft cervical collar, but be aware of it. With PS 5.0 and EPAP min 8.6 and max pressure 18, your pressure appears to be optimized and fluctuates very little. This looks like a PAP result that is very good, and while there are some unexplained desaturations in the oximetry, it also is pretty solid in the middle to upper 95-100 range most of the time. I think you could save some money and just buy your own recording oximeter that works with Oscar if you want to keep monitoring. There is nothing here that seems to require that monitoring.

RE: Need help interpreting Pulse Oximetry results
There seem to be a lot of pulse changes here, along with a flow graph that appears quite "furry". Maybe there's more to your condition than just plain OSA, particularly given that you're not feeling better with PAP therapy?

Did you have a sleep study that you can share a redacted report from? If so, did it look at leg/limb movements?

Hi,

I thought I replied to this, but anyway, I can share my initial sleep study or any recent Oscar data.  Let me know what works for you.  My sleep study was from 3 years ago and I don't think I have any charts.

Hi Mindbullets. Yes, please share what you have of your sleep study (with appropriate redaction).

RE: Need help interpreting Pulse Oximetry results
Thanks Mindbullets. So there was no measurement of leg movements, and I suspect that even if there had been the results would probably not be that useful given the number of obstructive events observed.

Compared to the baseline study, your OSA is very well controlled. One thing I notice in the 3 minute OSCAR grab is that your respiration rate is quite variable. It might be informative to see the Minute Ventilation and Respiration Rate charts from OSCAR for the full night of your recent SpO2 study.

Ok, here is Minute Vent and Respiration rate charts from that night.  Let me know if you need anything else.  I greatly appreciate your help!
