UARS, data interpretation OSCAR, what to do? - KingKongBingBong - 05-13-2021

I have had sleep issues for a years now, I suspect dating back even to when I was a young child. I believe I have UARS.
Sleep study results:

AHI 3.4/hr (15/hr during REM -> however all REM associated apneas during supine position, which I almost never sleep in - I only did so due to the bed positioning)
RDI 29.6/hr
PLM apnea index 3.4/hr

I have an insane amount of RERAs, so I have gotten a BiPap machine for this. The company I am trialling with gave me an Airsense 9 auto Bipap I believe as the 10 was not available atm... should I switch it out for the 10 when they get it or another machine? She told me there is no difference between 9 and 10, is this true? Surely not, the 9 is two decades old.

It's my understanding that using the 9 means RERA events are not measured, so how can I determine if I am getting these events? Any help would be appreciated, my data is below. I will add more sessions as the days go on! 

NOTE: I believe I fell asleep around 3am, I was on my computer until at least 2:45.

Hi KKBB

In there - plus everything else you need to know

http://www.apneaboard.com/wiki/index.php/OSCAR_-_The_Guide
This is an amazing guide. Both helped me heaps when i first started

RDI = AHI + RERAS

So your RERAS = 29.6 - 3.4 = 25.2 per hour

A pretty classical indication for UARS

How many run or blower hours on the 9?

Personally I'd request the AirCurve 10 VAuto.

Algorithm wise they should be very similar but you will have the machine for at least it's expected lifetime of 5 years.


RE: UARS how to interpret data!! - Gideon - 05-13-2021

You have an ASV. Very large difference.
A CPAP and BiLevel, except for the ASV work by maintaining pressure. ResMed ASV maintains lung volume, specifically Minute Vent.

There are reports of a very, very few doctors treating UARS with an ASV but I don't understand that reasoning.

So, how do you FEEL? The goal of any Apnea treatment is to get restful sleep and eliminate your symptoms. So gain, how do you feel.

SR comments?


RE: UARS how to interpret data!! - KingKongBingBong - 05-13-2021

Oh I was told it was a Bipap..


RE: UARS how to interpret data!! - Gideon - 05-13-2021

It (an ASV) is a BiPap, but one with a very specialized intent, that being to treat Central and Mixed Apnea.
It is the most expensive of all Apnea machines, and as such the hardest to get.

So far as I know, no one on AB has used an ASV to treat UARS.


RE: UARS how to interpret data!! - KingKongBingBong - 05-13-2021

Ok that's very odd - my main concern is, is it possible to treat UARS using ASV? Otherwise I'll give this machine back tomorrow and get a proper BiPap.


RE: UARS how to interpret data!! - Gideon - 05-13-2021

It is elevated PS that we use to combat UARS and Flow Limits that compose UARS. The common treatment entails the use of PS/Pressure Support to treat the Flow Limitations, sometimes with a fairly high PS. An ASV uses PS as its main tool in treating Central Sleep Apnea so yes it should.

Do note that for UARS that once the obvious (flagged) flow limits are treated we view the zoomed view looking for Flow Limits and arousals in the Flow Rate to see how we are doing.

The measure of success is the abatement of symptoms and how you are doing over all, your "numbers" look great, so how do you feel? Do we need to go further?

Let's wait for Sleeprider to respond here.
