As I gear up and start shaping up for my next attempt on Whitney, I am finding myself with new partners. Due to a knee injury sustained two years ago on our last attempt, Mom won't be hiking with me this year.

However, I have managed to garner myself a new partner (both on the trail and in my life wink ). However, this particular partner suffers from sleep apnea and uses a CPAP machine at home when he sleeps at night. This is a new realm for me as I've never really dealt with apnea before.

I am looking for any information pertaining to experience that any of you guys have had with apnea at altitude. We're looking at a multiple night trip and short of packing his CPAP and a solar charger up the mountain... I'm basically wondering if altitude makes things worse or effects it at all....

Thanks guys (and gals)!
