Help with settings for BIPAP? (UARS)

RE: Help with settings for BIPAP? (UARS)
I agree with Gideon, but will give you a link to read. http://www.apneaboard.com/wiki/index.php..._and_BiPAP This is one of several wiki articles we have on flow limitation. While they respond somewhat to pressure, it is pressure support (the difference between inhale pressure and exhale pressure) that treats the flow limitation which is the root cause of UARS. Pressure support is the increase in pressure as you inhale that counter-acts the upper airway restriction and results in a normal respiratory flow. If you do have UARS, pressure support is the answer, and PS 4 is the standard starting point.

Mode: Auto
Min EPAP=6
Max IPAP=20
PS=1

These are different from the above  because I want to see your Flow Rate curve to look for flow limits with a minimal amount of support.  PS=4 will minimize any flow limits. This is to confirm your assumption of UARS.

Hint, as a stomach/side sleeper try to keep your mask over the edge of your pillow.

What is the basis for you calling it UARS?
The typical tell is a high RDI and a low AHI.  Your sleep test, unless I missed it, did not address RERAS.

Charts
Use F12 to take your screenshots, it removes the calendar and pie chart thus presenting us with more data.

Always include a full night screenshot as it provides context plus data

Also provide several random 3-minute zoomed segment screenshot as this will allow us to check for flow limits, the root basis of UARS.


So I wasn't able to fall asleep for various nights, but last night I finally fell asleep with the mask on. I only slept around 35 minutes and woke up unable to breathe. It was similar to what happens when I sleep normally. I will randomly wake up unable to breathe. Then I start to breathe again and I'm fine. It was concerning though since I was using the machine and I don't think this should happen. I'm wondering if it was due to the PS being low? Or something else? Should I now change it to 4? Going to try to look at the data from the SD card now.

Nothing can be concluded without seeing the data. Your bilevel machine will not breathe when you don't spontaneously try to breathe. It can only follow your effort and make breathing easier. This kind of machine has no backup rate and cannot treat central apnea. If you are not breathing because of obstruction, then the EPAP min needs to be higher to keep the airway open. The solution to your sense of being unable to properly breathe depends on whether your airway is obstructed or open.

Here is the data from last night. Again, only around 30 minutes unfortunately.

Nothing in the data. Respiration looks normal, no events, flow limitation is not shown.

What would you recommend I do? Continue like this? Someone told me to lower the pressure 6 - 11 and raise the PS to 3. But I'm not sure if I should give that a try or continue as I am until I have more data. I just don't think the settings are right if I woke up because I stopped breathing.
