CPAP at higher altitudes

[woodg]

I'm going to be in Aspen, Colorado for a week at the end of this month and I'm wondering if there is anything that I should be aware of when I go there. Any extra items that I should make sure to take with me, different performance of the machine, things of that nature.

I'm aware that my machine does compensate for altitude difference, but I think I'm going to be at the upper limit of what it's supposed to compensate for. I'm just trying be ready for anything.

Thanks in advance for the advice.

If your machine compensates for altitude, you will be fine.

There was a thread recently about this. viewtopic/t58926/viewtopic.php?f=1&t=58 ... de#p550107
You may have to bump pressure if your machine runs at your upper limit or you are using it CPAP and not APAP. But it won't be more than 1 or 2 cm.

I spent Christmas week in the mountains of California at 6,000 feet. I don't know what the altitude of where you'll be is though. I had no problem where I was. I did take a spare mask and climalte line hose. No problem at the airport either.

P.S. Have a great trip.
P.S.S. If I was going above 8,000 ft. I would read posts to find out if there is anything I had to worry about. I do believe the S9 is adjustable to that number.

I've had some time today to do a little more research as to the altitude.

I'm going to be in Aspen and I've found information that shows the altitude at the airport from 7620- 8440 feet. I know that the place that I will be spending nights is a bit higher than this, but I don't know exactly where that will be or how much higher. I've also found that the published specifications for my machine state that it compensates up to 8500 feet. That would put me at or above the stated limit.

I also forgot to mention in my first post that I run my machine in CPAP mode. After a few months in Auto mode, I tried straight CPAP using the 95% number, and found that I got significantly better AHI in that mode.

I'm wondering if I should just use the Auto mode and if so, what range should I set. I'm currently running the straight CPAP at 10.8 and am averaging around 3.0 AHI which is mostly HI. I don't have the exact numbers right this moment.

Perhaps you can set a tight range of 10 - 12 cm, that should cover it.

Thanks for the suggestions. I think I'm going to try setting Auto at a ranger of 10-12. and see how that does. I'll post my results just for grins.
