Feedback on first night OSCAR data

Post by vtcpapuser » Sun Oct 27, 2024 8:19 am

Hi, just started using a CPAP. I've been trying to read up on how to interpret OSCAR data but would appreciate people's input. Using a Resmed N30 nasal cushion. Woke up feeling more rested than usual. I highlighted a couple of areas. One in the middle of the night and one early morning. Is that a leak from the mask in the middle of the night or bad SD card data? Had ramp off, 4-20 range and EPR 3. I'm thinking I'll try EPR off and see what happens? Or just bump up the minimum to 7 instead? Thank you!

Welcome! It's great to hear you felt more rested after using your machine. As you get more and more used to the new experience, I'm betting you'll fell more and more rested.

I don't know what happened in the weird gap; maybe someone else can tell us that.

You have a nearly constant low-level leak. This doesn't compromise your therapy, but you might sleep a little better without it. Try refitting your mask after watching some videos on how to fit your particular mask. You can also try using the machine and mask during the day or evening while you're awake and see what little adjustments will get you to zero leaks. It will probably be most useful to do this lying in bed and shifting around from one sleep position to another.

I'd say leave your EPR on at 2 and raise your minimum to 6. That way you'll get the benefit of EPR all night long and avoid any possible wake-ups from changes in how much your pressure drops when you exhale. (The machine can't go lower than 4, so if your EPR is 2 and your pressure is 5, you'll only get a drop of 1.)

If all goes well over several nights with EPR of 2 and minimum of 6, then I'd suggest you raise the EPR to 3 and the minimum to 7. This is partly for reasons of comfort and partly because EPR helps with flow limitations (unless they originate in your nose). But let's see how you do with EPR of 2 and min of 6 first.

You have a fair number of CAs toward the end of the night. I'm willing to bet those are coming after arousals. If that's right, then as you have fewer arousals, you'll have fewer CAs. So for now, just bracket the CAs. You can spot arousal breathing pretty easily; it's deeper and messier-looking than normal asleep breathing.

Thank you! That's really helpful. I'm going to give those things a try (mask fitting and change EPR and minimum). I did use a microSD card with adapter since I don't have an SD card reader but do have a microSD reader. Wonder if that did it. Resmed website says it'll work but not recommended due to not meeting medical device electronic standards or something. Will see how it looks the next few nights.

Better buy an SD to USB adapter for your computer. Those are cheap, and usually reliable (I had one break after many years of use).

If your recording gets messed up, during the night, because you use an SD to microSD adapter, there's nothing you can do about it.

If it's only the SD to USB adapter misbehaving while reading, you can see your correct data with another adapter.
