Rate my Resmed 10 VAuto deal from FB

[GrandCentral]

Found this on FB Marketplace and snapped it up for $350. How did I do?

   

Apparently grandpa bought it, tried on the mask once and refused to touch it again. Runtime of 0 hours. Looks and smells brand new.

I will be migrating from an AirSense 10 Auto but having lots of central events and I am hoping to reduce those. OSCAR screens below are from my AirSense 10.

What do you folks recommend for starting settings on the VAuto? I was planning on doing a factory reset and then using VAuto mode, Trigger high, TiMax around 2.5 or 2.7.

Wow!    That's an astonishingly low price for a 0-hour ResMed AirCurve 10 Vauto.  If you find it doesn't meet your needs you could easily sell it for a lot more than you paid for it.  

As to settings, others can advise you on those.

Thanks! Yeah that's pretty much what I thought when I saw it. Worth the trip to pick it up, and worst case I can resell it.

I am new to VAuto though and my doctor is not very helpful (wants me to switch to a fixed backup rate). And I am out of the country so I won't have access to English language assistance for a while.

Based on my APAP settings of 9-15cm I was thinking of starting at EPAP min 8, IPAP max 15, PS=4, VAuto mode. Just to collect some data and see how the charts look. I am hoping to get some more experienced opinions on that before I start.

I just sent my Vauto with 24K hours to Advans CPAP Supplier #28 for refurbishing. It will get a new motor and the hours reset and come back clean. It's a $220 service. Anytime you can get a Vauto with reasonable hours for a good price, it's a great deal. Even if it has significant hours on it, it's probably worth refurbishing.

GrandCentral, I notice that you have a large number of Central Apneas in your Oscar report.  Did you have a lot of CAs in your sleep study?  Are you brand new to using a pap machine?  If you are new the CAs might be treatment-emergent and will likely go away or lessen a lot as you adjust to therapy.

[Sleeprider]

If you're looking for settings, I'll suggest EPAP min 7.0, IPAP max 14.0, PS 3.0, Trigger sensitivity very-high for the centrals.

Hi Deborah K,

Yes, you and I discussed my centrals a couple of months ago on my post here. But here is the relevant bit from my sleep study:

Code:

I get mostly centrals. I've been doing APAP for over a year and it works fairly well, most nights around 5 AHI. But there are periods of days or weeks where I get AHI numbers up into the teens or 20's. And I can feel it the next day when I have nights like those.

Sleeprider -- Yes I am, and I will give those a try and report back. Thanks!

GrandCentral -- FWIW, my CAs virtually disappeared when I switched from an AirSense 10 AutoSet to an AirCurve 10 VAuto with trigger set to very high, as Sleeprider suggests.

[GrandCentral]

First night with the VAuto and it is a step up so far. Here is a whole night chart and a zoom to the "most eventful" 30 minutes of the night.

       

I am surprised at how much more comfortable it is to breath with the VAuto compared to the AirSense 10/11 AutoSet (I own both). Why isn't this the default unit for everyone? LOL. Sleep was great with no arousals that I can remember.

My "most eventful" 30 minutes coincided with some leaks detected so those might be related. Maybe need to tighten my mask strap or something there. I am using an Airfit P10 and find it a good mask for me.

Any thoughts or suggestions for improvement on the new charts would be appreciated. Thanks everyone!

[GrandCentral]

Apologies for thinking out loud, I am still trying to wrap my head around OSCAR data. But I will take a stab at interpreting my own charts.

It seems like:

• Pressure range is about right, it maxed out around 12
  
• Pressure increases preceded the CA events
  
• Possible fix would be to increase PS from 3 to 4 to get higher IPAP pressures with lower EPAP pressures
  
• Maybe lower TiMax a bit as well
  

Thanks for the help and encouragement AndyB, Deborah and Sleeprider. Please LMK what you think.
