Resmed U-Sleep Data

is anyone using this? If so, does anyone know what the difference is between the device metric: Apnea Index and Obstructive Airway Apnea Index? Also, which metrics are added up to arrive at the Apnea Hypopnea Index? It defintely isn't just the Hypopnea and Apnea Indexes added together.

Thank you in advance for any replies!

This is something that only DMEs and doctors will be using or having access to.

But they will be viewing the data that the machines collect. So it's the machine doing the gathering and reporting and this software just gathers it and reports it. It doesn't do any analyzing...the machine does the analyzing.

Yes it is just the Apnea Index and the Hyponea Index added together. The thing that may be throwing you off is with ResMed machines the Apnea Index includes the Obstructive apnea index and the Central Apnea Index...and if you have any unclassified/unknown apneas they get tossed in the Apnea Index basket too.

never heard of 'usleep'.

AHI is apneas (of any sort) and hypopneas, just like the name says.

AI is all apneas, OI is just obstructives.

Actually, I have access to it as well, Pugsy. My DME asked me to register on it, so that I may gather data too. I do see that it only reports data and does no analyzing whatsoever. If I add the Apnea Index to the Hypopnea Index it doesn't always add up to the Apnea Hypopnea Index in U-sleep. U-sleep reports Apnea Index, Hypopnea Index, Obstructive Airway Apnea Index, Central Apnea Index, RERA, and Unknown Apneas. There are some days that just make no sense and I can't figure out what goes into the Apnea Hypopnea Index. Figured I would inquire on here if anyone knew.

Thanks

I didn't even know that such a software/website was offered by ResMed for doctors and DMEs. No one here is likely to know anything about it.

If you really want to know exactly what your machine is recording...use ResScan...ResMed's official software and it has the last say so.

As to why the discrepancy...who knows. I do know the website should be reporting whatever data the machine gathers.
It's not going to be able to do any analyzing of anything because it doesn't have access to any of the actual files used to calculate things.

RERAs aren't ever part of the AHI
AHI is the Apnea Hyponea Index and the only events in those totals are
Hyponea Index
and the Apnea Index and the Apnea Index includes Obstructive, central and unknown apneas.
You can see this easily on a ResScan report.

I use a Mac...no Rescan for me!!!!

Thanks again, Pugsy, you're awesome!

Thanks, Palerider!

Bummer.
Of course you know you could always put WinBlows on the Mac.
But would kinda defeat the purpose of having a Mac though.

Just how much of a data difference/discrepancy are you seeing? Are we talking huge numbers or parts of numbers?
Like 10 vs less than 1 or something else.

Your DME should be able to run a ResScan comparison though...have you asked them?

I plan on asking them this week. I kind of feel like they would rather me not be so OCD about any numbers, but I can't help myself. I like to understand as much as I can. Oh well...as far as discrepancy goes...there always seems to be a .10 difference. It''s as if something else is going in that AHI number. I add up the AI and HI and it's almost always off by .10. Actually, if I add up the OAI and CAI and any Unknown Apneas, it sometimes is off by the .10. Maybe it's a rounding error...who knows! It just bothers me...it's not good to be an accountant in this Apnea world...I like everything to balance. No way, on the WinBlows. I was a Windows person for so long and converted to Mac 2 years ago and I LOVE it!

If it is just usually a 0.10 discrepancy my bet is on how things get rounded up or down.
And you are right...they won't be all that excited to find out you are digging this deep.
I am surprised they gave you U-Sleep to try instead of pushing MyAir which is designed for patients.

Good luck to you. While accountants might find 0.10 difference troubling.....in the grand scheme of things in the cpap world it doesn't even warrant more than a shrug of the shoulders. Therapy effectiveness isn't measure by anything that close.

the machine calculates it to more than 1 decimal.

get sleepyhead, it reports the data to two decimals, that might help with your rounding errors.

I'm really surprised that it's not MyAir reporting. What I saw on U-Sleep was that it was for DME's and provides Automated Patient Coaching. By sending patients notifications via email, phone or text based on whether they are doing well or struggling with their therapy.
As if we need more automated pressure when we are struggling.

The DME had me register on My Air as well. It just gives very little info. Actually, U-sleep does have several reporting options, just no graphs like Sleepyhead.
