What Frank said. The machine most likely detected apneas/hypopneas and that's why it increased the pressure.
If you decide to download the SleepyHead software, you may see that you are having a cluster of apnea events around that time every night.
Since you're new to using CPAP, 11.6 cm probably feels like a lot of air whooshing by your face. With time, you probably will sleep right through this when it happens, but for now, if it feels uncomfortable, I would cycle the power button just like you're doing.
One more thing, though - do you know what your EPR setting is? That's expiratory pressure relief, and it's a comfort setting to make it easier for you to exhale against pressure.
The setting can be 0, 1, 2, or 3. Three gives the most "relief" while exhaling against pressure. If your EPR is set to 0 or 1, you might try increasing it to 2 or 3.

Welcome to the Apnea Board!
Your CPAP pressure in your profile (4-11) does not match up with your message, can you please update it?
4 as a starting pressure seems low to me, especially if you are ending up over 11. I feel starved for air at 4. I have noticed that I wake up more at an rapid increase in pressure rather than the pressure itself, e.g going from 10 to 13 rapidly wakes me up, but getting there gradually does not. Starting at a high minimum pressure may (a) avoid the problems to begin with and (b) at least result is less different in pressure.
The best way to monitor and evaluate is with the SleepyHead software, see the link at the top of the page.
Thanks for the advice. I checked out the events in Sleepyhead Software and shows that the increase in pressure was immediately after a 30 sec Obstructive Apnea.
Cycling down the S10 and restarting it makes the mosts sense as I cannot wait for 20 minutes for the machine to sense I am no longer in Apnea. At least I still have a chance of nodding off back to sleep if I do this instinctively.
Chill suggested I increase my base pressure from 4 (which I did a few days ago to 6) to now maybe 7 or 8. That will decrease the jump from lower pressure to higher pressure on an apnea event, so I will try that.
A call to Resmed confirmed that it can take the S10 up to 20 minutes to back off the pressure
As I said, my MyAir scores are often at 96 - 98 out of 100 and I feel quite rested relative to my restfulness prior to starting about 38 days ago. Just that wakeup at 4.30am is a nuisance!

Thanks OpalRose and others ...
My 90% pressure is 9.7 - 10 for the past 30 days so based on that I can adjust my Min and Max Pressures to say Min 8 and Max 11. I will see how I go.
I have also been taping my mouth shut using a single strip of micropore tape and at the same time started wearing a Philips Dreamwear Nasal Mask. Using that combo, I got 2 nights AHI scores to 2.8 and 3.8 respectively.
I know it will be a process of tweaking over time.
Were you able to resolve this issue? If so, what worked? I'm 3 nights into my cpap therapy with my ResMed AirSense 10, and it also wakes me when it seems to get "stuck" at 12.5 once or twice a night. I don't know very much about this, but when the screen shows my pressure, it starts out at 4. The range it displays in the corner is 6-16. I have tried to make adjustments based on another thread here, but I can not figure out how to do so; (Will bust out the manuals tonight, as this issue is very annoying.) Also, I am still in my rental period with my Anthem insurance. Will making adjustments against my prescription range cause them to not buy the machine???
