[Equipment] Nasal mask over full face if suspected UARS??))

[Dashaman]

"Nasal continuous positive airway pressure (CPAP) is one treatment option that has been evaluated as a therapy for UARS"

Based on this study: ncbi.nlm.nih.gov/pmc/articles/PMC4608900/#:~:text=Nasal%20continuous%20positive%20airway%20pressure%20(CPAP)%20is%20one%20treatment%20option,different%20aspects%20of%20the%20condition.

It says I should use a nasal mask. I have a full face one and it's super hard to breathe through my mouth using it. Even with EPR.

RDI 28.1 from WatchPAT. Hospital study after resulted in "No apnea"

Please post some OSCAR charts. The links for downloading and using are in my signature.

If you are having difficulty breathing through your mouth with a FFM, we need to see data to help analyse it.

I'll get you some tomorrow. Last night I didn't put the SD card in so there was no data. Thanks for the help!

[Dashaman]

Here is some of the OSCAR data. Could you let me know what your expert eyes see?

[PeaceLoveAndPizza]

Experts? No experts here mate. We are simple folks who have been using CPAP for years and have been studying it through the eyes of those who came before us. It is all about CPAP users helping CPAP users.

For your specifics, it looks like the bulk of the spikes are arousals. You can see it in the flow rate and respiration rate. A wee bit of leaks, but nothing to be concerned with at this moment.

You do not need that wide pressure range as you stay between 7-9 with the current settings.

Some things to try as we figure out if the pressure support or low pressure is contributing to the arousals.

1. Set your pressure range to 7-10 with EPR 2 full-time. It is not much different from what you are using today other than lowering the upper bound. Try that and let us know how it goes.

2. Depending on how that goes, we should try increasing your pressure range to 8-11 or 9-12 with EPR set to 2 or 3. That will give us more data on how increasing pressure with EPR affects things.

Also turn off ramp unless it is absolutely necessary to fall asleep. 

We may need to have you try increasing pressure even further to see how things go. Managing arousals/RERAs/UARS is a finicky beastie. It takes some experimentation to find the balance between a good quality sleep and an acceptable number of arousals.

In the meantime, this wiki page has a lot of good information to ponder. https://www.apneaboard.com/wiki/index.ph...ng_therapy

I don't really know how to tell if the results are getting better.

7-10 and 8-11 pressures tried last night.
Also put mouth tape on - I seem to breathe easier when my mouth is closed in the FFM.

Please post the entire evening. if folks want to see something zoomed in they will ask. Also, please read the link in my signature “Organising your OSCAR charts”.

My instinct is that the arousals (spikes in flow rate and respiration rate) are the culprits. We typically deal with those using pressure, but try to be sensitive to how people respond to the pressure. 

If you are okay using mouth tape, you could consider using nasal pillows.
