[Treatment] Settings on Resmed Aircurve 10 VAuto
#1
Settings on Resmed Aircurve 10 VAuto
Hi,  I purchased a new Resmed Aircurve 10 Vauto due to the Philips recall and my system one being from 2014.  My BiPap Rx is old from 2008 but called for fixed 17/13 pressures at the time.   My AHI had been creeping up on my old system one from below 5 to in the 10 range with 25% leaks showing (I use a chin strap but still mouth leak and wake up with a dry mouth).  On the new system I wanted to try the auto BiPap so I set it up for min EPAP 7, max IPAP 20 and PS of 4.0 with the other settings at default.  I have used an ultramirage II nasal mask for many years and I like the way it fits/feels.  The first night I tried the Resmed N30i mask I got for $1.00 with the system and I couldn't sleep well at all with it and my AHI was high.  

Last night, I went back to my Ultramirage II and slept better with the following from the machine:  events per hour 9.8 (it was 28.2 on the N30i), mask seal happy face, pressure 13.0, exp. pressure 8.9, leak 47 L/min (my mouth leak??? the mask felt secure), Vt 440ml, RR 18, MV 8.1 L/min, Ti 1.2 s, I:E 1:1.6, spont cyc 94.5%, AHI 9.8, Total AI 8.0, Central AI 5.1.

Today I feel better than yesterday but still somewhat tired.   I felt like I leaked less from my mouth with the lower pressures and my mouth wasn't as dry as on the fixed BiPap at 17/13 I was used to on the System One.  I am wondering if you can give me suggested adjustments to my current Vauto settings and any other advice you can think of.  Is the central AI of 5.1 of concern?  Would different settings help this.  At my previous sleep study I was OSA with no central component I know of.  Thanks for your help!!

RE: Settings on Resmed Aircurve 10 VAuto
You really need to use OSCAR to see when and where your events are occurring.  The numbers don't show if it is a positional problem, or they are scattered thought the night.   You might try setting the "Trigger" setting to High or Very High, in an attempt to reduce the CAs, but this is just a guess without seeing detailed data.
