Several readers have asked how
worked for us...
and Irvine The Final Chapter:
"private" group—the B-Team used re-filled Poisk bottles,
Tom's A-team, the "public team"
used exclusively "SummitOxygen"
on Everest in the Spring of 2004.
SummitOxygen overall worked great for us! We did
have to make an adjustment to the equipment at ABC,
which was easy and basic for the climbers to do. At ABC
we also checked the pressure in each tank BEFORE taking
the bottles up the mountain. One bottle was empty, or
more likely had a bad valve. The others bottles had
varying amounts of pressure, which we noted.
The oxygen once up on the mountain
worked excellent, one climber reported getting 21 hours
out of a bottle! It is unclear what his flow rate was.
Caution to others: You should
remember that this oxygen is
highly flammable, smoking should be avoided around it.
We would recommend people spend time using it before
summit day, to get to know the equipment, and check your
bottles before you go high!.
Caution using other oxygen: We would
recommend people spend time using it before summit day,
to get to know the equipment, and check your bottles
before you go high!
Year after year we hear of people
with bad valves on bottles that
appear empty, check it before you go high! Of course,
there are a few who blame the equipment when maybe that
was not the real issue.
again worked great for us! Over time it could be a
significant change in Mt Everest climbing. Many
commercial expeditions have much invested in the old
system, therefore don't expect a quick change. Time also
should be taken to learn the new system. For much more on

An old fashioned Q&A. With hundreds of e-mails a day it is tough to keep up with
the everestnews.com e-mail, so submit your questions to
and we will try
to answer them as a group to be more effective.
We went to Mount Everest in search of an answer.
