New User with AHI going up

No dought about positional apnea, you need to get ahold of that. But let me suggest a couple other things. 

Set mode to Avaito
Set trigger to very high
Ps 4
Min 8
Max 20

Give those a try and get a collar for the positional apnea.

I'd take a little approach.  First, your PS (7cm) is very high.  I would like to see a pressure separation of around 4 cm.  Since the AC11 is so new, OSCAR doesn't currently support all its reporting parameters, I will provide you with instructions for both the "S" mode and the Auto mode.  Both modes described will support the same pressure.
"S" Mode: Set the EPAP pressure to 10cm and the IPAP to 14cm.
"Auto" Mode: Set the EPAP Min to 10cm and the IPAP Max to 14cm and the PS to 4cm.

Try turning off the ramp, it is delaying your therapy pressure.  Also, set the "Trigger" to "High".  If CAs persist, increase this setting to "Very High".  Leave "Cycle" alone.

Try these settings and report back here.

Yes, I did ask for a copy of my sleep study on Feb. 21 and began to educate myself on what all those numbers meant.  My AHI was 14.9 and 16.5 supine.  Obstructive events 12, central 6 and hypopneas 33. My mean SPO2 was 92.

On my second study with masks on March 26.  My AHI was 12.5 with central index 11.9.  Obstructive 0. The tech mentioned that at higher pressures my central events increased.

You can see why I am confused.

Thanks for caring.

Last night I tried to sleep on my side and used on one pillow instead of my usual two.  I'm happy to say that my AHI came down to 28.8 with "only 10.2 OAE" and 18.4 CAE.  I have some hope that maybe I can get the numbers down.
