I finally found a "mask" that I can keep on all night! (bleepsleep) I feel 10 times better in the morning and the wife says I am not snoring but when I look at data it looks concerning to me. Am I over reacting? Any advice?

Why did you change the max to 20 and then back to 16 again?

Some parts of the night you don't need so much and some parts you do which makes me think sleeping position.

Spend much time on your back?

I sleep on my back most if not all night. When I tried max 20 it just did not feel good. Should I try max 20 again?

You need more pressure at times during the night. If you are always on your back then the other factor is maybe REM sleep.
Both supine sleeping and REM stage sleep can worsen OSA and/or cause increased pressure needs to happen.

Notice how you maxed out at 16 a lot of the time? The machine wanted to go higher but couldn't.
Notice how your AHI is much lower when the machine could go higher...it did a better job of holding the airway open and preventing the airway from collapsing.

Now I also think you need more minimum pressure but I would go up slowly in 0.5 cm increments if it were me.
If letting the max go higher creates a problem...increase it slowly also....and 18 cm would be a better choice than the current 16.
Sometimes with a more optimal minimum pressure doing a better job preventing the airway from collapsing in the first place we find that the machine won't need to go as high.

It's all about prevention and not trying to fix something after it has happened.

And as for feeling so good at 20 max...you should have been asleep when that was hit. It's not a factor at all while awake unless when it goes higher it wakes you up but I always tend to believe that it's the apnea events causing the wake up more than the pressure changes.
The apnea events happen and the machine wants to prevent further apnea events (which wake us up) and then the pressure goes up.

If you are thinking that during an apnea event the pressure increases to blow the airway open....wrong thinking. None of these auto adjusting machines will do anything during an apnea event. They sit by and twiddle their little thumbs until the airway has collapsed and then opened back up and probably disturbed your sleep....and then they look back and think OMG I need to do a better job stopping that from happening again and then they increase the pressure.

Thanks, I will make some adjustments and see what happens!

Agreed, an increase in Min pressure should address the events before they exist.

While an increase in both minimum and maximum pressure will help, I think you'd get an even greater benefit by adjusting your sleep posture. If possible, sleep on your side rather than your back. If you use multiple pillows, lose them and just use a single pillow to support you with your head tilted slightly back to keep the throat extended. The clusters of events indicate to me that your apnea is at least partly due to posture, so these adjustments, together with a pressure change, should clear things up.
