Events won't come down


I have for 4 months used full mask for 7 to 9 hours per night. My initial study revealed 149 events per hour. I now am stuck at 25 to 35. My question is: "Why can’t I get the events down any further. I sleep sound and am not aware of the events."
Any suggestions appreciated.


You may need a ox concentrator OR, if you have one, you may need to have the level of ox adjusted to suit your needs. The same for your c-pap, a sleep mapper may be a better choice,(with Wi-Fi).


Are you on an Auto titrating machine? If so, what is the max pressure set at? If your events are that high, you may need a machine that can go higher than the standard 20cm. An auto BiLevel device may help.


Its a bummer getting stuck at an unacceptable level.

My untreated AHI was originally 65 but came down to about 15-20 with CPAP use. But then it got stuck. It took several more months of experimentation for me to get the right pressure and mask for the AHI to average below 5.

My experience was: Don’t give up. Keep trying different combinations of mask/pressure.


While unfortunate, the answer is very simple. Somewhere along the way you did not pay someone the appropriate fees.
