No.

The cause of the fragmented sleep must be identified first. You have to know what you're fixing before you try to fix it.
Muse-Inc wrote:Or, is it first treated with CPAP therapy to attempt to stablize sleep architecture and then re-evaluate as needed based on our experience?
If the cause of the sleep fragmentation is SDB, then yes, that would be appropriate.

Is it Brian Denehey's brother?
Here's my question to you...assuming the universal scale for AHI and RDI is 5-15=mild, 15-30=moderate, >30=severe, where does one fit that has an AHI of 19 but and RDI of 36?????

Standard linear numeric scale.
Numeric values may be any mixture of integer or floating point (exponential/scientific notation e.g. 4.336e11 and 4.336e-27 is supported). Linear scaling is used for plotting continuous numeric data; it may also be used with undefined series, such as lineplots when no X value is present in the data. Display of numerics is often controlled using a printf-spec
Do you realize that the "I" AHI and RDI stands for "times an hour"? (edited after Muffy's justified generic wisecrack) Do you realize that AHI is short for AI +HI?
RDI = (AI+HI +other respiratory effort related disturbance) = (AHI+other respiratory effort related disturbance).
RDI counts the number of times an hour that your sleep is interrupted by any respiratory event.
Look at the data you supplied, and reply:
What is your
total number of interruptions?
Look at the RDI severity scale. Where does your reply to the above question put you on that put you on that scale of severity of interruptions to one's sleep?
Look at the data you supplied, and reply:
How many sleep interruptions an hour (on average) do you have
that are not caused by Apneas or Hypopneas?

Generic edit inserted... and you won't believe how many times a minute I fixed that error during the original edit.... Lucky I have witty friends watching over me -- and over others too...

I am well aware of what the acronyms are and what they stand for. However, can you please provide the "RDI severity scale" you referred to? The only scale I can find is this one outlined about halfway down the page.

You have not replied to any of my questions, which were meant to help you out of your confusion. You are making assumptions that leave you upset an confused -- and clinging to them tenaciously.
I give up on trying to help you understand the issue.
Any other reader interested in the RDI scale accepted by the American Academy of Sleep Medicine will find it clearly linked to in previous posts on this very thread.

In order for you to provide me help, we must first agree on the fundamentals: 1) are AHI and RDI the same index? 2) Do they measure the same things? 3) Do they use the same scale?
Now, once you can answer these questions, I should be able to answer yours. In case you need some help, the following links ought to clear things up for you

I hope I'm not offending anyone either! The facts are the facts. Period. AHI and RDI are not the same, and neither are the scales used to score them! I would think with all of your knowledge you would know that these terms and scoring mechanisms are all too often used as though they are the same. For those that are trying for the first time to comprehend their PSG report, it is confusing enough without adding terms and scores that sometimes mean the same and sometimes mean something different. Do like I did and spend hours researching the differences between RDI and AHI, and how they are often used synonymously. Perhaps this link will help you!

With respect, Ace, I spent plenty of time researching when I first was diagnosed. I read quite a few "long-winded diatribes" of which I comprehended maybe a quarter. But as I read more, I began to understand more. That's true, even today, nearly a year after I received my diagnosis.

Please speak for yourself and not the rest of us newbies, lazy.... I learn a tremendous amount from this board including the "technical diatribes" I may barely understand at first!
