RERA's are they all that important?
So I'm typically getting some good AHI numbers on my machine, under 1.0. However, ever since I started using OSCAR, I've seen that I get a lot of RERA per night. As I understand it, RERAs are some sort of micro-awakenings during the night. If it's a micro-awakening, does it really count as an event that affects your sleep? It doesn't seem to get counted in the AHI numbers.
Also what would cause a RERA? Could changing your sleep position at night count as a RERA?
Machine is a Philips Dreamstation. Yes, I know about the recall.
RE: RERA's are they all that important?
I'm sure you'll get some better, more detailed answers. I'll just say that like apnea, a few are acceptable. the significance of rera for you lies mostly in how you feel. if not up to par, then they may be significant, and vice versa. but think about it. these are 'arousals', precisely the opposite of what we're all trying to achieve - restful uninterrupted sleep.
 I have no particular qualifications or expertise with respect to the apnea/cpap/sleep related content of my posts beyond my own user experiences and what I've learned from others on this site. Each of us bears the burden of evaluating the validity and applicability of what we read here before acting on it.

RERAS are mini arousals, which can affect sleep. See the Wiki article below:
https://en.m.wikipedia.org/wiki/Respirat...ance_index
"RERAs are arousals from sleep that do not technically meet the definitions of apneas or hypopneas, but do disrupt sleep and cause symptoms."

RE: RERA's are they all that important?
Okay, yes they are supposedly arousals, but the second thing I noticed is that I don't notice them! According to some of the reports, I could have had up to 20 of them per night or even more, but the number of times I've actually gotten up is much less, and usually I wake up only 2 or 3 times a night. And getting up is only due to having to go to the bathroom. Could these RERA's be false positives? Or are RERA's just a pattern of breathing that might possibly lead to arousal, but may not either? That is, an indicator to an arousal, but not necessarily the arousal itself?
My machine's own software, Dreammapper, never tracks RERA's, I've only noticed it ever since using OSCAR. Could it be that the manufacturer (Philips) doesn't trust its own RERA readings and doesn't bother reporting it because it's not accurate?
RE: RERA's are they all that important?
Go by how you feel in the morning. If you don't notice RERAs, then don't worry about it.
As far as being "real" or not, I don't know. Post a daily chart from OSCAR for advice. DreamMapper isn't going to give you much information.
Just to clarify, OSCAR only reports what your DreamStation writes to the SD card.
RE: RERA's are they all that important?
Dreammapper is not a clinical quality software, but a patient directed software to encourage compliance. Take a look at Oscar around the RERA events. Do you see a flattened inspiratory wave? That is inspiratory flow limitation and practically a prerequisite of RERA. If RERA does not bother you, how do you feel since starting therapy? Are you statisfied with your sleep.
RE: RERA's are they all that important?
It depends. As far as being real, yes they are. Frequently they arouse you enough to change your sleep state, but not wake you up. We don't like them showing up simply because they disrupt your sleep.
Treatment is the same as treating flow limits.
Bottom line is if they are not bothering you ignore them.

"the second thing I noticed is that I don't notice them!"
I'm not aware of my residual apnea & hypopnea events. I'm not aware of my all too frequent flow limitations & occasional palatal prolapse. I'm not aware of my periodic limb movements and most of my leaks. yet individually & collectively these things seriously screw up my sleep.

No, no differences in flow that I noticed. The only thing that I see is different is a graph called "Time at Pressure", which has a bit of a peak, only at that time.

Yes, but shouldn't you be aware of those times you woke up? The apneas and hypopneas don't wake you up, usually.
RE: RERA's are they all that important?
If you know how to zoom in on the respiration rate (see the Organizing your Oscar Charts in my signature), you will see the problem. If not, and you don't care, then I'm fine with that too.
