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.

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.
Machine: ResMed Aircurve 10 VAuto BiPAP Mask Type: Other Mask Make & Model: AirFit P10 For Her Humidifier: Unsure CPAP Pressure: None CPAP Software: OSCAR
I had it set to 6 - 14 and PS of 3 (following what someone told me on here). Then someone else told me to try 7-10 because they said the range was too large. So I did that, and the first night my AHI was 1.50 (a bit more than the other nights at 0.9) but the second night it was 3.80 and I felt horrible the next day. I only slept an hour with the machine on, and then woke up and took it off.
What should I do? Trying to titrate myself since I have no doctor here in Mexico who can help.

BIPAP Titrate for UARS
I am wondering if someone can look at this (especially flow rate) and tell me what I could change. I have tested various settings and this is what I have noticed:
I seemed to sleep longer with EPAP at 7, PS 3, and IPAP at 10, but I did not feel any relief whatsoever and the flow rate seemed to show flow limitations on inhale.
When I had EPAP at 8 and 9 it made me feel like I had air bubbles inside my lungs and throat. Would this indicate it needs to be lower? Do I just need to get used to the air bubbles or is it something actually detrimental for UARS?
I am trying to figure out where to leave EPAP. Then deal with IPAP and PS from there....
I've attached last night's data. EPAP 6, IPAP, 11, PS 5. I slept very poorly and only for an hour.
My BIPAP is the Aircurve 10 VAuto from ResMed. I feel like the mask I used gives me leaks (nasal pillows).
I don't have an answer, but advise that you update your profile to include your CPAP and mask name and type. To help, I am including a link to your profile edit options.

What evidence is there for a diagnosis of UARS? Please note, I don't doubt you... just wondering how it was diagnosed.
You have no apnea, no reras, no Hypopneas. There are no Obstructives showing, so no reason to raise Epap. I don't see much FL, although chart is hard to read.
When you post a chart, please use the link in my signature line to guide you as far as Organization of the chart.
Use the F12 key (on a Mac, Fn+F12) to take a Screenshot.
You can try a lower PS setting and see if that lowers the CA's. Try a setting of 4 for a few days.
