ASV and (another) High Altitude Question

We're headed to a wedding in Lima and off to the Andes for a few days. Not overly concerned about Machu Picchu as the elevation there is 8,000 feet; however, Cusco is much higher at 11,000. To ward off altitude sickness, I already got my prescription for Diamox and will be drinking cocoa tea. Any concerns about my PR960 ASV? I am hoping that it will actually help me sleep better than most by treating altitude-induced CAs.

In case it has any bearing, I do rather well with my machine settings at the lower end of the spectrum. Machine settings and last night's statistics are below:

• Settings:
  EPAP Min: 8
  EPAP Max: 15
  PS: 6
  IPAP Min: 14
  IPAP Max: 25
  
  Last night:
  EPAP 95%: 9
  IPAP 95%: 15
  PTBs: 83.5%
  PB: 0%
  OA: 0
  CA: 0
  HYP: 0.56
  AHI: 0.56

How should I expect my machine to perform? Any concerns?

I don't know that you will see or feel any differences in performance.
The machine will attempt to compensate for the altitude changes as best it can and there's not much we can do about it.
How it actually compensates I don't really understand but again since I can't do much about it I haven't tried real hard to understand it.

I will say that I have used my PR S1 model 760 at about 12,500 altitude one weekend when we camped in the mountains in Utah and I didn't notice a thing difference and actually never even thought about it until after the fact.
Checked my data and all that and nothing really changed in terms of anything. Machine responded pretty much like it always did and the AHI was pretty much what it always was and I slept great and felt great. I did NOT see evidence of the machine going to pressures that I normally don't see. If I didn't know the dates at the higher altitude I wouldn't be able to spot any changes in the reports that would point to a higher altitude. Pretty much same old reports just a different date.

Have a good time and enjoy the trip and take whatever extra precautions might be needed to make sure nothing that is preventable isn't covered and it sounds like you are doing that.

Report back and let us know if you spot anything unusual on the reports or how you feel. Not many people here get a chance to use their equipment at these altitudes so we don't have a lot of experience to draw upon.

Typically they compensate up to 8500 feet per the manufacturers (One more correction of misinformation). I agree with Pugsy concerning higher altitudes. With an ASV in auto mode the machine should provide the necessary pressure for your conditions anyway.

Thank you for the replies. Sounds like I shouldn't have any issues. I'll post back after the trip.

Maybe a trip to new mexico for a back up resmed aircurve asv for $500, although it is a 2015...

Or this one if you are going through atlanta, for $500 obo for a resmed aircurve asv...

Funny how they both refence 50 hours of usage...

If you are getting UA and H. raise the min epap a cm or 2.

If you are getting UA and H.

One needs to note that the Respironics ASV machines don't do UAs...they separate centrals and obstructives on their reporting.
Now the ResMed ASV (and other high end specialty machines) do NOT separate centrals and obstructive apneas so they all go in the UA basket.

Incorrect... if you have the machine you say you do.
Maybe you don't have the AirCurve 10 ASV you said you had...

Altitude Adjustment Automatic Up To 8500 Feet

From the spec sheet on the AirCurve 10 ASV. Don't believe me...look it up. I just did and found it easily.

I am not aware of any machine that states anything above 8500 ft in terms of auto adjusting for altitude.
Everything I have ever seen has been 8500 or lower (depends on the brand and model).

Pugsy's information is verified in the aircurve 10 ASV manual, available with a google search.

xxyzx wrote: the OP does not have an aircurve 10

Duh...I know that and his question was already answered.
I was responding to your incorrect statement that

xxyzx wrote: mine corrects to 10000

and since you have already stated you have the AirCurve 10 ASV I was merely correcting your error.

You have said repeatedly that no one ever corrects you (even put it in your signature line) because you are never wrong (cough, cough)...which is simply not true but you just choose to ignore any corrections made to your incorrect or incomplete posts...so I fixed that one for everyone to see. Front and center and easy to find. No abstract interpretation of reading something someone said about something far out in left field.
This one is nice and easy and clear to understand.

Have a nice day.

Ha....cpap humor (he tried to get out of bed with FFM on) with a veiled sex joke (spouse says now that you have yours on maybe you can help get mine on) on this CBS sitcom just now.

At least it was a little funny, although another scene had him making a weird noise while sleeping on the couch (snoring or choking or an obstructive apnea) with the kids watching him before they woke him up.

Well, that's how I interpreted it.

Not to change the topic, though, carry on!

ResMed AirCurve 10 ASV Manual

Page 17:

Operating Altitude: Sea level to 8,500' (2,591 m); air pressure range 1013 hPa to
738 hPa

I'm assuming I have the correct manual here. Pugsy or TASmart, please correct me if I'm wrong.

EDIT: I realize this is not related to the original question. I was just posting a link to a legitimate source to further support correct information due to incorrect information posted by xxyzx, and I wanted to make sure I had the right manual. Pretty sure I do.

But you also lied twice in the same thread and were definitively caught in your lie!

Just to be clear...I realize the post I made with the link to a manual was not related to the OP's question. I was just correcting a post made by
xxyzx and providing proof within the thread where the error was made.

Just got back from Peru. At higher altitudes (Cusco ~12,000ft), I did see a slight increase in my AHI - all HYPs but the machine kept OAs and CAs at bay. I went from an AHI average of 1.0 to 3.5.
