Richard, from your posted graph at 12 cm pressure, I don't see therapy problems there. The flow limitation is a bit high, but events are within reasonable bounds. CPAP has a couple objectives, and one of the most important is to provide less disturbed sleep. So AHI is not the whole deal. If you sleep better with fewer leaks, and still have a treated AHI <5, then that beats disrupted sleep throughout the night. Keep working on it, and good things will happen as you eventually find that magic combination of mask, fit and pressure.
With the strap made by my wife and at 12 I seem to be have a lot less trouble with the mask
And my ahi is around 1.
I will keep it like this for a week then try going up a bit.
It's not their fault but I get annoyed having to pay the same amount for postage as I do for the product. Mind you it still is not expensive but the one my wife made seems to be working ok for now
The combination of dropping pressure to 12 and the strap my wife made is producing good results
Low leakage and low ahi often under 1.
I will try going back to pressure of 15 soon but if I have problems I am going back to above.
I am traveling at the moment so have not tried the amara mask but will
[/size]Unless one actually knows what one's oxygen saturation is during the night, it is prudent to attempt to return to the prescribed pressure. One should move slowly and make adjustments as needed along the way to reduce any leakage. The other alternatinve, in my mind, would be to leave the pressure where it is and get one's oxygen saturation checked for a few nights. If everything OK, go with it and as Sleeprider says do not worry about it any longer.
