OSCAR help

[wendyf77]

        I downloaded OSCAR and checked out the wiki, but I have still have no idea how to tell what the problem is.  Uploading last 2 night data.

I see several things that need changing:

Set your pressure range at 7 to 15.

Turn on EPR full-time, set at 3.

If you can handle it, turn off ramp.  You get no therapy during ramp, and any time you get up, ramp starts again when you return to bed, robbing you of therapy.  Try it.  If you can't let go of ramp yet, set ramp to start at pressure 5, and run it for a shorter time.

You are having Positional Apnea. That's why your AHI is so much higher on 9-1 than it was on 8-31. PA cannot be corrected by setting changes. It occurs when your chin is tipped toward your chest, and shows on your chart when a lot of events are clustered together. Some folks can solve this by sleeping on a flatter pillow, but most need to wear a soft cervical collar that is tall enough to hold their chin up. Drugstores usually sell a couple, and Amazon sells loads of different ones.

Your Oscar chart is pretty good, but we need to see the following all on one page:

Event Flags
Flow Rate
Pressure
Leak Rate
Flow Limits

We need to be able to read to the bottom of the Flow Limits.

Best of luck with your new therapy!

I'm not sure how to get that data

Hi wendyyf77 welcome to the forum, your 99.5 percent pressure is 11cm so you really need around 9.6cm min pressure with EPR on 1, and to share a full screenshot please hit F12 while in the daily tab to save, and upload that screenshot (it will save in your pictures folder). And you're hitting your max pressure so please raise it to 14cm.

I will do that tonight when I get home.  I did try the settings the first person suggested and my leak limit and events on myAir were 1.2 (LL) and 5 events.  I also woke up multiple times and pulled the masks off at some point because I felt like I couldn't breath and mouth was very dry this morning.

[wendyf77]

Is this what is needed or do you need to see the charts themselves?  I included last night's because that was after I made changes suggested.

You are having positional apnea.  You can see positional apnea where either H or Oa events are clustered together.  Getting rid of as many as you can will lower your AHI.  Positional apnea can NOT be controlled by pressure changes.  You have to find out what position you are getting into and cutting off your own airway.  Have you changed your sleep position?  Sleeping on your back?  Using more (or new) pillows?  These things can cause positional apnea by chin dropping to your sternum and cutting your airway.  Think of it of a kinked hose – nothing can get through – you have to unkink the hose…

IF you can’t make a simple change like changing to a flatter pillow helps then you will need a collar.  I have a link to collars in my signature at the bottom of the page.  It shows people who are not wearing a collar and the SAME person wearing a collar.  There is a huge difference between the two.
 

And I think you have problems with flow limits but that chart is missing.  If you take your mouse and put it on the bottom line of each graph you can click on it with the button and pull the bottom up and decrease that chats size.  By doing that with the ones above the flow limits you can get it on your next screenshot.

This is data from last night and today when I took a nap.  I used a cervical collar for the first time last night and only slept 2 hours with both it and mask on because one side of my nose was clogged.  Took nap today wearing both.  My seal doesn't seem like it was good last night, but I also put mask on after collar, reversed that today.  Could the clogged nose account for the event or RERA?

When you have it zoomed in like you did for the top screenshot, we  can't see what is going on except for the tiny part that is zoomed into.  You can zoon in using the up arrow and zoom out with the down arrow.

The 2nd one showed no positional apnea but a very large amount of flow limits.  To help with the flow limits you need the setting for EPR to be set to full time and 3 is the amount.  It looked likke you could have it on 2 so give EPR 3 a try.

last night's data wearing collar, mask, and using a flatter pillow.  EPR is set at 3
