Thanks, Doric C, for mask suggestions. I also have a cover-nose mask, and a nose-cushion one, but not at my current address. Will try them later. Thanks also, Rested Gal, for machine-capability-listing, and much help earlier in my epic. My next project is to find a data-capable machine. Regards, May...

Continuing thanks to all. I sleep with the machine at 11 cmH20 all night. Just a couple of times, when I woke at 1 am or so for a bathroom visit, I left it off to see what happens, and I didn't feel I slept well then. The machine and I coexist nicely. The mask isn't perfect, and on occasions my eyes...

Slept without the machine for one night, and woke gasping. Slept with the machine first half of night (OK), and then without it for the second half (woke gasping). Took pressure up to 11 cm, and had a good sleep. I think I'm about "there". Rather too much mask leakage, but that's a small matter to f...

Thanks for all input - am reading avidly. Am now sleeping with 10 cm CPAP, after pausing at 8 cm as advised. No significant problem wearing the mask. Last night I woke two hours later than usual to visit the bathroom, a good sign. After that I slept with the mask off, and awoke gasping. I think I'm ...

Thank you, Snoredog. Could you please indicate what model machines might provide the feedback info to help me more? Having just also found and bought a second machine in a garage sale for $5, I'm encouraged to think I can find them for almost nothing. BUT I've found that the sellers often have no id...

Here's another study where CPAP therapy was as successful without a sleep study as with one: http://meeting.chestjournal.org/cgi/content/abstract/124/4/227S-a In this case, doctors empirically set the CPAP pressure for the non-sleep-study patients without adverse effects. Their average pressure was ...

Thank you all - again. I will read the article with great interest. Last night I went to 6 cmH2O and wore the device for 8 hours. Tonight, I'll go to 8 cm, so you can see I'm getting to levels that you've mentioned are most likely to be helpful. More in due course.

Thank you all. I appreciate the input - lots.

Den, thanks for your reassuring input. I found it particularly interesting that 10 cmH2O was once a universal setting. I am wondering if there is any setting on a machine that is too-high for safety. I somehow doubt it, or we would have heard of the negatives. In another post, a contributor reports ...

I am quite sure I have sleep apnea from my symptoms of waking gasping, and finding myself short of oxygen for a while, not to mention snoring. I bought a CPAP machine (REMstar Lite), and am wondering if I can set my own pressure as foillows (I have already found out how to do the adjustment). Start ...
