First night very high numbers
#1
Hello Apnea Board. I'm new here, just recently diagnosed. Love the board and appreciate all the info / help.
I'm 33 year old male, physically fit.

Last night was my first night on the machine and i feel horrible today, don't feel i slept well. I understand it will take some time to get used to and I'm okay with that. What I'm really concerned about is the high numbers of AHI I'm seeing in SleepyHead for my first night. My sleep study a few weeks ago put my AHI at 12. Lastnights AHI shows as 20.55. Seeing this AHI data and the other events is really scaring me thinking something else is wrong. 
I know this is only 1 day but I'm really concerned with the results.

I'm going to post several screenshots of last nights SleepyHead data. I'm just looking for some general guidance on how these numbers look? Is it possible my AHI is so high due to leaks? Any help / input would be greatly appreciated.

Note: Ignore the first afternoon session, it was just testing.

Added images of sleepyhead data for second night

Made some adjustments the second night and the difference of results seems significant.
Adjustments made:
1. Turned Flex ON to A-Flex and set to 3 
The first night I had this setting turned OFF as I initially thought it was uncomfortable. After doing some further testing with it ON versus OFF I realized that without this setting turned ON, the air seems to blow all out of the mask much more (leaks) and doesn't seem to have a vacuum like fit / seal unless its turned ON. I could also feel my airway opening wider each inhale on with this setting turned ON. I think this was the setting that made the significant difference for me.
2. Raised minimum pressure to 7, max to 11.5

Second nights results:

I'm not sure why I have so many sessions listed for this night, I only turned it off once or twice. Sleepyhead has this night separated in sessions of 1 hour?

Welcome.  You need four posts before you can use link.  We can figure out links with spaces in them.

First, don't worry.  Take a deep breath.  Relax.  You are going to be fine.

The higher AHI was likely due to the fact that you were awake much of the night.  The machine does not know if you are awake or soundly asleep and your breathing while awake can look like breathing events.  This is very, very common.  In the sleep lab, the monitor your brain waves and can tell if you are awake and discard data when you are not sleeping.

It could also be that your Flex settings are causing central apnea events, reducing Flex usually fixes this (assuming you don't actually have central apnea!).

Flex setting do not cause central events. I would listen if anyone has any case studies proving otherwise.

Two things come to mind for me. Possibly you were not fully titrated in supine or rem sleep. Or your have oral leaking. Either or both will cause high numbers.

I would need to see your sleep study results and your download from last night to make a verdict.

Thanks very much for warm welcome. Yeah trying not to worry to much. I did sleep some though, was only fully awake a few times. 
I turned the flex option completely off as it seemed when i did some testing it was much more comfortable with it off. Not sure if that effects the numbers as well.

I'm going to post the links to the screencasts with some spaces.

Thanks man. I actually sleep on my back and do not move at all (its very odd). My sleep study showed it, 100% back sleeper.

I have flex turned off. Going to wait until I have 4 posts in order to post the images.

Fihappy, post a couple more times, and the images won't be a problem, or just add some spaces to the links. Did you have a titration study where you were evaluated on a CPAP to determine your pressures? I'm guessing not.

Will do. I only had a home sleep study from the doctor. Ares I believe.
