Aircurve 11 ASV cant tell I'm breathing.
#1
Question 
Aircurve 11 ASV cant tell I'm breathing.
Hello,
I awaken multiple times, and the machine very forcefully attempts to get me to breathe in it's established pattern, making it impossible for me to fall back asleep. I have to power down, and restart to enter ramp-up, hopefully to fall asleep on the first attempt.
This machine obviously cannot tell that I am breathing. 
Any thoughts appreciated.
Thanks.

Welcome to Apnea Board,

I would suggest you get the free OSCAR program so you can see the sleep data. You'll also need to attach it to a post. We'll need this data to understand what the ASV is doing, what it's trying to accomplish. There's not enough info in this post.

To get the data to OSCAR, you'll need an SD card inserted in the slot on the left side of the ASV before sleeping to capture detailed data.

I've used the ResMed AirCurve 10 ASV and it'll be much the same with settings. You'll need to know what it's set to. You need to tell us what X is for each of these settings:

Mode X
EPAP pressure X
PS X

If you're using Ramp, it'll likely hinder ASV therapy.
Mask Primer

Positional Apnea

Attach OSCAR, etc.

RE: Aircurve 11 ASV cant tell I'm breathing.
The Resmed ASV machines are pretty good at setting rate and volume targets, but you're describing problems while you're awake. A common problem results from masking up before you have settled and breathing normally. Deep slow breathing gives the Resmed ASV a false target, and this can be very confusing. Resmed uses your last 90 seconds of respiration rate and volume to set its targets for respiration, so if you're not relaxed and breathing normally, it can seem the machine is at odds with your respiration as sleep onsets. Hard to tell you what to do, but this is an anxiety issue, not a hardware issue.
