use of cpap machine at hiigh altitude

[thimarine]

I have not asked a question for a year or two, maybe longer, and know this has been asked and answered, but I can't seem to find the answer to the question---Do I need to make any adjustment to my machine when I go to Denver next month? I live in Indiana. My machine is set at 9 with a max of 16. The VA had it set wide open at 4-18. I changed it. My avg. pressure is 10.3, AHI 0.2. Do I need to do anything about the high altitude? I would appreciate any help. I do not have a pulmunologist. The VA just gave me the machine about 7 years ago after my sleep study with no instruction. I was told to read the manual or go online. I am leaving in 3 weeks and would really like to know if there is anything I need to change. I am getting a letter from my primary care provider that I am carrying a medical device to get through TSA. I hope that helps. I have not flown since being on CPAP.

Thanks in advance.

You will not have any problems with the TSA.. You really do not need the letter. The TSA is used to seeing CPAP machines. You are allowed to carry the CPAP in addition to your normal carry-on. Most machines have an altitude adjustment. It should be noted in your manual.

Thanks, that was going to be my next question as to how they counted as a carry on. I"m flying Southwest which seems to be pretty liberal about these things.
