Interpreting and Optimizing machine
I am new to this and have browsed a lot and was recommended I look at my data to get better optimizations. I've been diagnosed with severe sleep apnea, I've posted my day 3 and 4 charts to see if there's anything I can change. The Machine was setup by my doctor with the recommended settings. Let me know if I need to share more details! Thanks in advance!
I've also for fun sent these images to chatgpt and it recommended me change my range from 7-15 to 6-12.
RE: Interpreting and Optimizing machine
If you want to reduce your Hs, you should increase your minimum pressure to 8 cm in the first step. Unfortunately, this might increase your CAs, so there is a tradeoff.
Your doctor set the EPR to RAMP only, probably because of the high number of CAs observed. He should have your sleep report; you probably had many CAs. If so, then you should let the EPR setting be as it is.
You might want to turn the RAM off because there is no treatment during this period.
RE: Interpreting and Optimizing machine
Please check your sleep study to see whether you did in fact have a bunch of CAs during your sleep test. It's quite possible you did, but it's also quite possible your CAs are "treatment-emergent." That's pretty common, and the CAs tend to start going away on their own as your body gets used to CPAP.
Aside from a few periods of large leaks, and aside from those CAs, your charts look good. You're sleeping through the night with the machine, which is great. Your flow limitations are pretty good.
You could simply turn Ramp off, as G. Szabo suggests. If you want to leave it on, please raise the minimum to 7. Only then will you experience your full ramp EPR of 3. (EPR drops the pressure by a set amount when you exhale, but the machine can't go lower than a pressure of 4.)
If you like the feel of EPR, you can introduce full-time it once your CAs settle down a little.
