Wow. An S7. That's an old beast!
First, read this. All of it.

Section Three of that will tell you how to get the Clinician Manual which will, in turn, tell you how to get inside the "special menu" to access the pressure settings.
Then, read this.

It is how to adjust your CPAP pressure based on YOU and your needs.
The main thing to remember is to go slow. Real slow. It may be tempting to speed the process up but you aren't doing yourself any good by doing that. You need data (even if that is just "how you feel" data) and one night is not enough. Too much goes into a night's sleep.
The second thing to do is to start a sleep journal. Before you go to bed, write down what kind of day you had. Good, bad, stress level, medications, new foods, fun day, work day. Did you make any changes? Log it all down. In the morning, write down how you feel. Dreams, no dreams, rested, zombie, woke up a lot, didn't, whatever. Log it all down. You want this all down so that you can track the changes. So you can look back and see that Friday night binges with the co-workers mean you wake up feeling like crap BUT you feel not-as-crappy since you raised the pressure from 6 to 6.5. See?
Two final suggestions.
- Contact the doc and get a copy of your sleep data or at least what pressure they suggested you start with. That would really, really help.
- Consider upgrading that machine. It is way old and, if I remember correctly, it uses a smart card that requires a special card and reader. If you are going to be doing this on your own, then you need a data-capable autoPAP. Check out the list here:
