AHI is great but what causes all of these RERA's?

So how many RERAs are there?
Doesn't look like very many to me.

According to this, 9 RERA's. I do wake up a lot and I am suspecting I wake up with each one. I never gasp for air. I just open my eyes and look at the clock.

the pressure would be interesting to see - and a close up (2 minutes) of the 2 RERAs around 0:30 as well.

9 over 7 hours isn't an extraordinarily high number given the rest of the data looks super good.
RERAs could maybe mean an arousal from some sort of breathing event or it might just be the way the machine is interpreting the air flow.
These machines can't really detect arousals. What they do is try to flag breathing that looks like breathing when we do have an arousal.

As to what causes them...if the are real...the airway tries to close up just a little and we have an arousal. If we saw a large number of RERAs along with the other usual signs of the airway trying to collapse (snores, Flow Limitations, OAs, hyponeas) then more pressure would be the ticket but I don't know that these few RERAs in the absence of the other warning signs really means very much.
One would need to take into account how they feel they slept in general and how they feel during the day before worrying about RERAs all by themselves. If you think these are related to wake ups and affecting sleep quality then they are usually easily dealt with by using just a little more minimum pressure.
Some wake ups are just a normal part of the sleep cycle. Like did you know it is normal to wake after a REM cycle?

And how do you know that you wake up with each one of these? Do you keep a notebook and note the time?

The official definition of a Respironics RERA is
http://sleepyhead.sourceforge.net/wiki/ ... r_Glossary

RERA

Respiratory Event Related Arousal... a sequence of breaths characterized by increasing respiratory effort leading to an arousal from sleep, but which does not meet criteria for an apnea or hypopnea.”

RERA Detection in the Respironics System One data..Respiratory effort-related arousal..defined as an arousal from sleep that follows a 10 second or longer sequence of breaths that are characterized by increasing respiratory effort, but which does not meet criteria for an apenea or hypopnea. Snoring, though usually associated with this condition need not be present. The RERA algorithm monitors for a sequence of breaths that exhibit both a subtle reduction in airflow and progressive flow limitation. If this breath sequence is terminated by a sudden increase in airflow along with the absence of flow limitation, and the event does not meet the conditions for an apnea or hypopnea, a RERA is indicated.

So I have an app on my iphone that tracks my sleeping based on breathing. The picture is my last nights result along with the other data I provided.

So you have the phone right in front of your face the whole time and it has sensors to detect changes in respiration?

Maybe try this for a few nights when you wake up during the night. Reach over and turn the machine off and then right back on again.
That way you will have a for sure marker for when you were awake during the night and then see if it correlates to anything on your software reports.

Or consider spending some dollars and getting one of the new FitBit devices that measures heart rate and sleep and has some science behind it.

FWIW, I used to have a fair number of arousals. I had to get a new Sleep Dr. and when I went to her I showed her that I was having some minor desaturation issues. She said it looked like I might be having desats. going into Rem and might need more pressure. She ordered another titration. When I did the titration the technician told me she had to bump my pressure all the way to 18 to get the snoring to stop. Now none of this may apply to you but one of the first things I noticed when checking my Sleepyhead data was that I do not usually have Snores or any RERA's reported any more. Based on my experience I would wonder if possibly you need more pressure? Maybe Pugsy or one of the knowledgeable people here (not alphabet boy) will chime in.
