[Treatment] UARS With BiPAP - Looking for Some Guidance

[Sleepy541]

I was diagnosed with UARS/mild sleep apnea last year (pRDI of 9.4 and O2 nadir of 91%). I was originally prescribed APAP therapy, and had a very low AHI but no improvement in tiredness.

To improve tiredness, I am now on an AirCurve 10 in auto mode with a PS of 4.2. Unfortunately, I am still tired after a few weeks using these settings and was hoping you might have some advice for improving my tiredness issues.

I have included a couple of screenshots from OSCAR below. The first is from a full night, and the second is zoomed in on the flow rate during a period of (what appears to be) relatively stable sleep.

Thanks for any help you can provide!

I would like you to try adding a bit more pressure and reducing pressure support a tad. Something like:

EPAP min 6 (you could use 5 if the 6 feels too high)
IPAP max 12
PS 4
Trigger very high

The trigger sensitivity should handle the CA’s and the pressure should help smooth out the flow rate without hopefully causing more events. I think pressure changes responding to things should be minimal.

We may need to tweak up or down a bit depending on how things go. Give it a try and let us know how things go.

Thank you for your guidance! I will give these settings a go starting tonight and follow up.

Hi Sleepy

did you find success with some settings ?

Hi Sleepy

did you find success with some settings ?

Hello! Yes, changing the trigger setting really helped me with the clear airways. I have also increased the pressure support over time. However, I continue to experience tiredness issues. I am not sure how much of that, if any, can be attributed to the machine settings though.

My current configuration is:
Min EPAP - 4.2
Max IPAP - 25.0
PS - 6.4
Ti Max - 4.0s
Trigger - Very High

did you fell better then before using BIPAP ?

Yes, I would say that I do. I am also sleeping more soundly throughout the night and not waking up as much.
