[CPAP] Been reading and adjusting, ready for advice

[killoda]

            Hello all, I'm new to CPAP and have been using the Resmed 11 for two months now.  I had to buy an online sleep study and buy my own machine - so i'm serious about improved sleep.  I found and downloaded Oscar early on and have been using that data and the smart folks on this forum to tweak settings up to this point by reading a gazillion past posts and responses.  There is a lot to digest.  Over that time I have turned off ramp, moved pressure to 10-17 currently with EPR set to 2.  I have manual humidity (3) and hose temp (70) setup for my comfort.  Full faced mask.  My numbers have improved and I am now ready for advice from the gurus.  I am not thin skinned, tell me what you think.   Attached are 3 different days of examples - the two most recent days and one a couple of days earlier.  Mask leaks are usually from me scratching an itch...I can't help it.  

Is top pressure too high or does the pressure ceiling matter as long as it is high enough?
CA's seem to be more than expected but it maybe this isn't a big concern.

Sincerely,
David, San Juan Islands, Washington

Welcome to the forum killoda, you're on the right path and your therapy is looking decent, I would although raise your min pressure to 10.6cm to help with the scattering of OA events, and lower your max to 15.6cm to tighten up the range a bit more and see how it goes for a few nights. I don't see too many CA events nor clustering..

It looks to me that you are sensitive to flow limits. I would try EPR 3 and see how you feel at that setting.

Thx all.  Set machine as indicated to try for a few days.  I went 11-16, EPR 3.  One question remains:

How does it help to close the gap between minimum pressure and maximum pressure?  If I never reach say max of 16, why not let machine setting be 20?

The suggestions were to try to help with the increasing/decreasing of pressures. If you have more up and down in pressure the more disturbance of sleep.

Because of this some people do better on a static pressure like min and max the same pressure.
