Some pretty exciting data has been compiled over the last few weeks using rebreathers on Everest. O2 saturation levels exceeded even the best hopes!For those of you that are interested in climbing or are just curious about CCR use for less than 1 ATA check out the link below.
Caudwell Xtreme Everest
We were able to overcome many of the obstacles that have prevented rebreathers from a successful summit in the past--one of the biggest advantages to our system is the ability for the ExtendAir scrubber to work at -30C instantly, without a pre-breath, as well as the fact that the cartridges can be frozen solid for weeks, loaded and used (try that with granules) I of course may be a bit biased
On another interesting note--our Expedition members saved the life of a women left for dead by her own team--check out this link for the story
