What do the numbers mean? - WarrenW - 10-06-2024
[attachment=70496]
Finally Installed OSCAR and had a look at the data - wow there is a lot to look at. I am struggling with the whole CPAP process. When ever the pressure gets close to 9 it wakes me up. My AHI scores are low between 1.7-3 but I wondered if the set-up of my Airsense 11 is correct. It is in APAP from 5-15, and I have a full face mask (Phillips Dreamwear). What "scores" do I need to pay attention to? My sleep clinic person is useless, and my GP is also not helpful. Suggestions for dissecting the numbers?

Hi WarrenW! -
First, the graphs are displayed in order of importance. Please make sure that you are scrolled to the top of the screen so we may see the Flow Rate. The AHI and Time at Pressure are insignificant for therapy analysis.
Now, I would suggest that you turn the ramp feature off. It's really not doing you any favors. Some of your problems could be related to pressure changes. You might try setting your pressure range 9 minimum - 10 maximum. This seems to be your "sweet spot" pressure range. This may not be the perfect pressure range, but it will provide you feedback on improving your sleep.
Keep us informed,

Yeah, it would help us help you if you set your chart up a bit differently. What we need to see on page one are the following, in the order given, and no more charts:
Event Flags
Flow Rate
Pressure
Leak Rate
Flow Limits.
Also, we need to be able to read to the very bottom of the Flow Limits.

Why do these specialists set EPR at 3 but still set minimum pressure at 5 when they know the pressure won't go to lower than 4? So 5 - 7 minus 3 results in 4 4 4 anyway.
I'd start by making the pressure 7-15 so EPR works across the range and get rid of ramping which does anything but make the breathing gradual, as much as it starves me of air until the minimum of 7 is reached.

The user can't possibly know better than the expert that isn't using CPAP.
Signed a sarcastic guy.

Is there an easy way to re-arrange the graphs? I could not see a way to do that in OSCAR - it has only bee installed two days...
RE: What do the numbers mean? - Crimson Nape - 10-07-2024
Yes. Move your mouse pointer to where the label is displayed. When moving the mouse over to that area, your pointer should change to a hand or something other than the pointer. At point, left-click and drag the graph up or down. If you wish, you can create multiple graph layouts and store them in the Layout button at the bottom of the screen. Also, if you get carried away and wish to bring them back to the original order, go to View > Reset Graphs.
One thing to consider, the default graph order is in the order of importance for analysis.
