OSCAR Data - Low AHI but still not feeling great, and are these real OA events? - Santino - 09-26-2024
I'm a new CPAP user of about a month. I took a lofta test and had AHI of 7 but RDI of 17.
On CPAP, so far my AHI is usually 2 or less, but my AHI doesn't always seem to correlate all that well with how I feel the next day. Two nights ago I had an AHI of .52 but felt like I didn't sleep that well at all. By contrast, last night I had an AHI of 1.68 but felt fairly well rested. In general, I haven't felt any eureka moment yet and I still feel like I'm not sleeping solidly through the night, perhaps because my body is getting used to CPAP.
I am also concerned that part of the issue is I may still be experiencing a lot of RERAs that are not being effectively addressed. So far I have been slowly ramping up my minimum pressure in hopes of addressing this possible issue while keeping the max pressure relatively low due to fear of leaks and pressure swings waking me up.
I'd appreciate help in determining whether OAs that are flagged are in fact actually OAs. Most nights there are few OAs flagged, but others there are a fair handful, last night included. However when I look at the flow rate some of them look like I had an arousal BEFORE the flow rate dropped off, so it isn't clear to me they are actually OAs. The first attached image is an example. By contrast, the second attached image looks more like a legit OA?
I'm also attaching a zoomed out image of last night. I can also add an image of the night prior (when I didn't feel well rested despite the lower AHI) if helpful. In addition to my specific question about the OAs, I'd appreciate any suggestions about possible pressure modifications or any other suggestions based on the data. Thanks!

Welcome to the forum Santino, those are valid OA events. I'd need to see the whole chart zoomed in so I could scan it (SleepHQ lets us do that) to confirm if you have reras unflagged in there, but for now you need to raise your min pressure to 8cm and raise max pressure to 11cm, you can leave EPR on @ 3 for now.

Thanks! Good to know about the OAs. I can give those pressure settings a shot.

Sure thing! Could you please try the new settings tonight before bed for 30 minutes or so to see how they feel?
