It is the REMStar Pro with C-Flex, which explains why the manual altitude setting was dropped after my other model. Ah, good! Thanks! --DR
From: KB on 23 Apr 2008 00:59 Thanks, Dan, That would be interesting to see. I'm sponsoring 12 children there, plus 2 more children that I correspond with and then my dad sponsors 2 children in Bolivia too. So, I'm going to be visiting with 16 children, most of them individually. I can't wait. I'm so excited! I don't know how much time I will have to sitesee though.

From: KB on 23 Apr 2008 01:02 I have the Goodnight one. They told me that the CPAP machine wouldn't work at all at the 14,000 feet. So, they suggested to take my older CPAP machine with me. That's why I'm trying to figure out what is equivalent for number 7 pressure on sea level, so that I could set it manually.

What is an autoPAP? I have a CPAP, but the one that has altitude adjustment doesn't work at 14,000 feet. It will shut off.
