OSA -> CSA?
#51
RE: OSA -> CSA?
Thank you for the feedback! I appreciate it!

My doctor set the machine as follows. Min EPAP = 6; Max EPAP = 12; Min PS = 4; Max PS = 10.

Why do you recommend a wider PS range?

Thank you again!

3-15 PS is default. EPAP is something that you always "touch" or feel its effects. Although PS is set by you yet your ASV only uses what is needed. I myself got great results from titrating the EPAP and more or less leaving PS as defaults.

I do know the ASV must add PS onto EPAP to get your IPAP, I had the idea PS is only added in smaller increments to give an IPAP, where EPAP ranges more frequently up and down the range.

You could try what doc wants and let us see the data along with your user comments.

RE: OSA -> CSA?
Here is the titration protocol for ASVauto using the Aircurve 10 Vauto. Note that EPAP min can be affected by CPAP experience where the minimum pressure needed to prevent obstructive apnea is known.  While default starting settings are EPAP min 5.0, EPAP max 15.0, PS min 3.0 and PS max 15.0, we will often reduce the maximum EPAP and PS to make therapy more comfortable.  In theory, the machine only provides what you need, but there are many reasons that we reduce pressures from this recommendations. The bottom line is, it appears your doctor is using his best judgement to merge your CPAP experience with the rest of his experience with ASV. Like us, he may make changes as he sees the results.

RE: OSA -> CSA?
Hi everyone! I appreciate the feedback from all of you. My first two nights on ASV were terrible. I wasn't been able to use it for more than a couple of hours on each of these two nights. My AHI is far higher than it was with APAP. It feels like I am using APAP with EPR set at 0 (which I never did because of how uncomfortable that was). Last night, I woke up from aerophagia. Can someone please suggest how I should proceed with using the ASV?

Thanks so much.

Due to aerophagia, it's possible to dial it back a bit and help you get used to the ASV. Give an OSCAR so we see what's been going on and then suggestions are easier to come up with. We'd need data anyway to compare before and after adjusting downward. I've had aerophagia before and found a slightly raised head area and sleeping on the left helps also. At least with me it did so.
