RE: First Night
Welcome, and congratulations on starting PAP therapy!
Today, please set your machine up *outside* your bedroom during the day or evening and try using it for a couple of hours while your read, watch TV, or use your devices. This will speed up the process of getting used to the new experience.
You may be experiencing some sleep/wake transition glitches. These are likely to go away as your body gets used to the pressurized air at night.
Do you experience nasal congestion? I ask because (judging from the left panel) it seems you are having a fair amount of flow limitation, which might be (or might not be) messing with your sleep. If the problem is in your nose, you need to treat the congestion (e.g., with Flonase, which takes a week or two to kick in). But if the problem is further down in your airway, a little more EPR might help.
During this first week, as you're trying to get used to everything, I'd suggest you set your min and max both to 7 and your EPR to 3. Let us know how that goes.
When you post your next chart, please show all and only these graphs:
