Changing the pressure of a DeVillbiss CPAP machine (9001D)

Howdy!

Once again, I rear my head momentarily to seek some help before disappearing for months on end...

A bit of an update:

It's interesting that after two sleep studies, I was put on a CPAP machine with a pressure of 16 (which effectively reduced the number of apneas I was experiencing an hour from 30 without a machine to 11.5), when you consider what happened next: My doctor posited that the high setting was causing central apneas, and thus turned it down to 13. I started having more apneas - about 14 per hour. So, they decided to put my on an APAP machine - for posterity's sake, really. On average, it adjusted the pressure to 10-11 and at that pressure I was down to about 2-3 apneas an hour. Not too shabby!

It's also worth noting that I've been trying out various masks too. I started on a nasal one, switched to a full-face mask, and then another full-face mask (a newer one with a pliable, gel interior), and now I'm back to a nasal mask again (but with a chin strap this time). I'm not convinced that it's working out though so I will probably go back to the newer face mask, even if it's a little more uncomfortable.

And this brings us up to date. I'm going to end up purchasing an APAP machine I think, but before I can do that I need to wait for the insurance-related paperwork to go through and that's been a bit of a mess. Suffice to say, my 'free rental' period ran out, so I can either rent a machine (and I can't really afford it, being a student bachelor) or borrow my uncle's machine. My uncle's machine, the DeVilbiss CPAP that I mentioned in the subject heading, has barely been used. I figure that for a week or so, I can make due.

But the technician set the pressure to 13, because I only had a prescription for that pressure and another for 16. I went to put it at 10, because I think I'll sleep better and have fewer apneas. Right now, I'm tired and lethargic and I know for a fact that 13 didn't help me out that much before. So, can anyone walk me through the necessary steps? Or link me to a website (or forum post) wherein they are laid out? I took a cursory glance around but couldn't find anything.

Thanks in advance! And thanks for putting up with all of my rambling. :)

Here's a link to download the manual. See if you can figure it out from the instructions on Page 7 - 8.

Here's another link in CPAPTALK where the instructions were listed, too.
