Help With OSCAR Data Interpretation

[enaess]

Relatively new to CPAP therapy. When I use my CPAP I feel considerably more weary and exhausted the following day. I'm not sure what I am doing wrong. Any advice would be much appreciated. Won't be seeing a sleep specialist until next year unfortunately. Should I switch to CPAP? Lower or increase my pressures?

Note that the other thread for your therapy was a focus on treatment emergent Central Apnea. The CA was determined there that CA in OSCAR are due mostly because your body needs to get used to CPAP. You did have 8 CA in the sleep study, so they're a bit of an issue that hopefully stays low.

Here, let's set those CA aside for a minute. Let's deal with the OSCAR charts presented here. Yes CAI has about 3 that is adding to the AHI. But there's more on the other Apnea now above the 2-3 CAI. And that needs addressed.

OA is right at 3, Hypopnea are 1.3, combined 4.3 or so. OK to address these, again forgetting CA intentionally for now.

You need to keep therapy hours as close to 8 as possible. Your Max pressure needs increased, I'd try 15 to 16 max. The reason is you need to address the events not labeled CA. You can see your pressure line hits and stays at the top frequently, that's the visual indicator Max needs to go up.

I would begin increasing the max while watching all the events for a drop or increase. You can post the OSCAR chart after the edit for comment.

PS if the CA does increase will you try to lower the other events, you might need to get the ResMed AirCurve 10 or 11 VAuto in an attempt to avoid CA.

What has helped me is to raise the minimum pressure to provide continuous therapy I need to reduce AHI.  Median pressure tells me where to set my minimum pressure.  My median runs around 12 so I set min. to 12.  One of your OSCAR reports shows median pressure of 12.2

Your max pressure is not high enough.  The APAP pegs out at the top of the pressure graph wanting to go higher.  You can raise it also to accommodate what is needed to maintain therapy.  I use 20 to start then if after many reports 20 is not reached I lower it to 18.

I have found with a higher min pressure I have less need for 20 max pressure and my AHI goes down below 1 as long as leaks are under control.
