ASV setting help

ASV setting help
Hi There, 

Was wondering if I could get some assistance on adjusting my ASV settings. Recently, i feel like there is to much air pressure when I switched from ASV to ASV Auto. Unfortunately, doctor is unavailable to assist since my device is no longer connects to 3G carrier. They cannot adjust the settings remotely, so I have to wait couple of months for a visit.

Feel like I wake up sometimes with burping or back soar. Feel tired still when I wake up. As for sleep position, I tend to sleep on my stomach using a cpap pillow.

Appreciate any help and insight

Thank you!

RE: ASV setting help
Welcome back to Apnea Board,

Certainly there's a few things you can do to address your therapy.

I would edit all settings, EPAP Min and Max, and PS Min and Max.

Here's my setting suggestion:

ASV Auto mode
EPAP 7-12
PS 4-15

Reasoning? You might get better results with a slightly higher EPAP start, and similar with shortening the EPAP Max, this should make PS come in a bit earlier than settings right now.

Short busts of PS will also be easier to deal with. I don't see why you'd not be able to lower PS min slightly and also reduce the possibility of extra high PS again to make it more comfortable.

Math on the ASV, EPAP plus PS equals IPAP. However this ASV will Max out at IPAP Max 25, yours flat tops at times, because it's trying to indicate it wants to increase further, but cannot.

This leads to another issue. Hypopnea. I think with the clusters involved, you're also dealing with some Positional Apnea. Suggested steps are making sure you're using a flatter pillow, other measures to prevent chin tuck, or failing this, to look at a soft cervical collar.

Positional Apnea isn't just the sleep position doctors are concerned with when Apnea are being tested. It is the kinking off the airway physically and externally. So it will require physical external prevention.

At times, your leak rates are probably hindering as well.

Back to settings, you can do these yourself in about 2 minutes total. Don't bother waiting for the doctor. Get your copy of the CPAP Setup manual, focus on your ResMed AirCurve 10 ASV.

I will say I wear a mouthguard too and sometimes that can affect my breathing since I time to clench.
