On those machines, CPAP mode switches you to a "CPAP report mode" that does not contain some of the data you get if you use the machine in Auto mode. By setting those machines at Auto with min=max, you get a far more detailed report.

Thanks. As a ResMed user, for whom it doesn't apply, now I understand.

Re: Flow Limitations, it records as somewhat diminished or restricted airflow(I think 50% reduction but not sure), but does not qualify as an hypopnea. On the M Series in straight cpap that graph does not appearin the data, only on auto setting or the same min/max. I don't know about the Resmeds.

I know! I was just thinking I wish Dori would come live with me!

If you insist, but you've never seen me in the morning, definitely no wings in sight!! On the serious side, it's my husband who's the hero in all this. He's been haunted physically and mentally by his war injuries until this day, and yet he accepted cpap as just another battle to be won with no complaint and no whining. I'm very proud of him and grateful that he trusted me enough to do this.

Dori, you really are a treasure. Both to your husband, and to this message board.

So is your husband...to this country.

I've experimented with bed and pillow configurations and haven't been able to improve on several wake-ups every night. I think I might be sleeping deeper now as I find the pain is greater when I do wake up.

I wonder if you could be having spontaneous arousals from pain issues. Arousals, even if not respiratory related, can wreck sleep architecture and leave a person still very tired or sleepy the next day. Arousals aren't the same thing as "awakenings." You wouldn't be aware of the "arousals" at all even if many were happening all through the night.

Was an index for "spontaneous" arousals mentioned at all anywhere in your report, even if the index was reported as 0?

The person making obvious effort to breathe, but airflow lessening due to airway beginning to collapse. Brain sending a signal to open the airway better, before there's enough time to make the O2 levels drop enough to score the event as an apnea or a hypopnea.

I'd try first...what ozij suggested about trying a single fixed pressure.
If it were me, I'd probably set the fixed pressure at 12. According to the titration table that BleepingBeauty kindly posted for you, 12 was the only pressure that was being used both long enough and during REM sleep (when most apneas hit most people) and got pretty good results at that pressure.
