I have the Simplus and the F20. I am not sure if you are aware but the Simplus is meant to be worn a little low on the nose. I also found that with the Simplus I would don the mask and turn on the machine. Then I would pull the mask away from my face a little to ensure that the cushions got inflated. Your pressure is fairly high so the lower straps will need to be fairly tight. The upper straps should not hold the forehead stabilizer hard against your forehead. Do you feel the leaks or is it what you see on Sleepyhead?
I like the F20 even better than the Simplus. With the F20 you need to slide the nasal bridge portion of the cushion up your nose until it rests against your brow. It makes a lot of its seal against the brow. Then put the rest of the mask against your face and fasten the headstraps. The lower straps will probably need to be tighter than the upper straps. It took me a little while to get the F20 set up properly and it seemed to work better the more that I used it.
I still get the best leakage results with the Resmed Mirage Quattro but a lot of people can not stand the mask. I get excellent results with it. In fact two nights this week I got four zeros for leak rate for the night. That is min=0, median=0, 95%=0 and maximum=0 for the night.
If you can feel your leaks, let us know where you are feeling them.
Thanks, PaytonA, for your detailed response. Good to know how both the Simplus and F20 should rest on my face.
I honestly cannot recall anything different from the 17th compared with both the 18th and 19th. I was wearing the Simplus FFM all 3 nights and like you, I place the mask on prior to turning on the machine and pull the mask away to inflate the cushions. Perhaps my lower straps are not tight enough, given my high pressure.
Once I get the mask adjusted, I do not feel any leaks when I go to bed; I tend to fall asleep fairly easily and quickly. I wake up feeling rested and the large leaks do not wake me up during the night so I am a little frustrated in the morning when I see leak rates like the 18th and 19th. I will add that in the past (say 6 or 7 months ago) I would remove my mask off in my sleep, not even knowing I was doing this and I would wake up seeing the mask besides me on top of my machine. I wonder if the large leaks back then would cause me to remove my mask in my sleep.
The only time I feel the leaks are when I'm barely waking up and my alarm is going off; I do feel the leaks near my eyes. At this point, I am turning off my machine, removing my mask and getting out of bed.
I tried the F20 for the first time last night so here are the results: http://imgur.com/ET1LYbI
I plan on wearing the F20 tonight and making some adjustments to the straps; hopefully I'll see improvement!
