Ah, I see where you're going with this. True.

I think my settings are pretty spot-on considering my min/median/95/max..

I'll always have "noise" of some sort in my graphs - no biggie there. I'm not chasing that magical zero, but I would like to get rid of those pesky obstructions if possible.

Most nights are a bit more fragmented than that one - I'm usually showing 2-3 on/offs per night. (I always try to switch off before removing my mask so I don't clutter up my reports )

Since our S9 machines "chase" events, you could try adding a wee bit more min pressure over the next week or so, but with so few OAs and most in those deeper sleep cycles, I am doubtful this will produce much of a reduction. I toyed with this going from 10 to 10.4 but I didn't see any improvement so I went back to my prescribed min pressure of 10.

I did a home cpap study and was really unsure about what to expect. I was told by my physician that I had sleep apnea. Therefore a cpap study was needed. Unbenounced to me I purchased a mask and tubing and during the study I let them know that the mask did not fit properly. I thought that during the study THEY were to ensure the mask fit properly. I complained about the mask twice and was finally told at the end of the study that I could possible use the nasal pillow mask. Well the study ended and it was inconclusive because of low use. I was left with a mask and tubing and no machine. Is it common to just purchase a mask during a home cpap study? I feel like Ive been taken advantage of.
