I would say it depends on the "man".

As well as the analysis software version.

Received my sleep study report today! Really impressed with the responsiveness of the 1800cpap folks! Totally not sure what I'm looking at, and will be speaking soon to a rep, but thought I'd throw out some findings that you may be able to help translate for me and/or generate questions I should ask. From the report:

AHI: 35
RI: 39
OAI: 21
UAI and CAI: both 0
ODI: 23
Avg. saturation: 94
Lowest saturation: 77
Max pulse: 196
Avg pulse: 74
All apneas obstructive, none unclassified, central or mixed
Rx for AutoSet with Easy breathe at default settings

THANKS,
Gracie

You get to pick out a machine.

Look in my signature line for SleepyHead GLossary and a lot of the acronyms are defined there

AHI is average per hour (total number of events during the night divided by hours asleep)...at 35 you earn the severe category.

Your oxygen levels dropped to 77% for at least part of the night. They don't really say how much of a part but it doesn't really matter at this point. You got the diagnosis so now you get to start the treatment.

Not sure what ODI is...the I is index but not sure of the other part.

RI...again not sure...not and index that we normally see...now RDI yeah that is Respiratory Disturbance Index

OAI....obstructive apnea index as opposed to hyponea or central index.

UAI is probably Unknown Apnea Index...CAI is probably Central Apnea Index...both zero anyway.

Very well could be...that's a lot of desats in an hour if they go by the 4 % drop rule. Pretty much guaranteed to give a person a total crap day.

Yes. Oxygen Desaturization Index

Do you think the S9 currently for sale by Rise is one I should consider?

Oops, Desaturation. (Very tiny print) Parameters section shows 4%.

Yep, it's a great machine, low hours and you really can't go wrong with the S9 Autoset.
Fair price too.
I paid $250 for one a while back and it had over 2500 hours on it and no heated hose and I was tickled to death because even with those hours it was a steal.
It was for a family member whose machine died.

S9 Autosets don't last long on the forum. It would served you well.

Glad that test worked out and now you have a diagnosis. I would look around on craigslist first for someone local. An APAP by Resmed or Respironics would be the only two choices I would pick.

Comments,

Why wouldn't you buy a new S9 Autoset from a DME as most of us do? Then you will have a warranty if anything breaks down. If yes then look under the machine at the year that it was manufactured. I wouldn't buy the machine if it was older than 2 years. Resmed keeps improving their products as time goes by.

Thanks, Avi. Good points. Currently I'm uninsured and looking to keep costs low.

Flow limitation and flow limitation with snoring are calculated and are used to adjust the RI (Risk Indicator) using slightly different weighted factors. Those factors are calculated as:
RI = [AHI + 10(0.8 X FL + 1.2 X FS)] / If

where:
RI = risk indicator (RDI)
AHI = apnea-hypopnea index
FL = number of flow limited breaths without snoring
FS = number of flow limited breaths with snoring
If = total number of breaths counted

Flow limitation with snoring is weighted slightly higher compared to a flow limitation without snoring. (Weighting factor for FL with snoring is 1.2 and without snoring is 0.8).

Piece o'cake, huh?

Oh, yeah! Easy peasy! Thanks for chiming in, Mollete. I will admit to snoring like a rhino, and to not understanding much of what you said.
