Reducing my pressure

[SeaPappy23]

I have been losing weight and figured out how to reduce my pressure to avoid the following issues:

• air leaking out my lips, even when my mouth it totally closed
  swallowing of air and resulting vomiting

What I have noticed is that when my leak number is high, this corresponds with bouts of excessive bloating and vomiting. Air leaks out my lips even when it is totally closed (teeth together). I tried taping my lips shut but this made the bloating WAY worse. So, I figured out how to reduce my pressure and noticed last night that when I reduced it from 8 to 7, the mouth leak was less. Reducing it to 6 eliminated the mouth leak. My question is this: How accurate is the ResMed S9's AHI reading? If it says I am having no or very few apneas, am I safe to reduce the pressure?

Yes, if your AHI remains 5.0 or under and you are feeling good or better then you are doing okay at the lower pressure. But don't take just one night's data for it. See what a week's data w/no other changes has to say.

This is just my opinion ... I would not lower the air pressure without first getting a 'go ahead' from a sleep doctor. The level of pressure coming from your CPAP is like a prescription, and it is not the best thing to "self medicate" if you know what I mean.

I agree it would be better to first talk to your sleep doctor. The AHI reading is very accurate on the S9, so if you're not seeing a high AHI then that's good.

If you have ResScan 3.10 for the S9 then what you can do is check what your average pressure is per night and also the pressure on preivous nights events when the pressure has increased. If the pressure isnT increasing and your pressure is set too high then you could gradually lower it to reduce the pressure, but you don't want to reduce it too much below the point of apneas your having.

OK, so my prescription is for "8". Last night tried "5" and still... 0.4 AHI. I feel rested. How could they have gotten such a high reading for me a month ago when i went in for my titration? Has losing 10 pounds made this dramatic of a difference?

I am using the S9 in CPAP mode. I am thinking of changing it to AutoSet mode and setting the range from like 2-8. Would I need the software then to determine what my actual required pressure was?
