I'm assuming that I turn a lot in the night and its during these turns that the seals are getting stressed and leaking some air. Maybe I should just train myself to sleep on my back all night. I've been a side sleeper mostly all my life. You mentioned that it appears EPR ramp is not turned on. How do I check this?  I have the ramp time set to auto and EPR Type to Ramp Only. Start Pressure(under ramp time) is at 4.0.

If you set the Ramp Start to 4 cm it will not do anything as that is the minimum pressure the way you have your machine set up. If you change your minimum pressure to 9 cm, and keep the Ramp time on Auto, I would suggest setting your Ramp Start to 6 or 7 cm, or what feels comfortable to you when you are awake. It will hold the pressure at that say 7 cm and apply the EPR during the ramp time, but when you go to sleep it will ramp to 9 cm at 1 cm per minute.

If you do need a chin strap, pay attention to when you are breathing through your mouth.  If you're breathing OUT through your mouth, EPR or Bi-Level might help, since that will lower the pressure on expiration.  If you're breathing IN through your mouth, then your pressure might be too low, or you might be suffering from nasal congestion, which can be caused by the wrong humidity levels....

Your only events are hypopnea, and EPR can actually work to minimize that, but in your case the event rate is already low. EPR for you will be a comfort setting. Along with your new minimum pressure of 9.0, try EPR Full Time at 2. You can increase or decrease it according to your comfort. I see no drawback to using EPR and I think you will like the results.

Just to make sure I am understanding it right...if I want a min pressure of 12 cm(the goal is 9 cm but since epr is 3 I'm setting it to 12), would a ramp start pressure of 9 cm be good for starters? My EPR type is currently set to full time. I'm a bit confused.
