i dont know yet...
Edmund Hillary used oxygen from tanks on his back when he climbed to the summit of Mount Everest.
1. Experienced limbers no longer use oxygen tanks as a matter of course. 2. It is possible to manage without oxygen, even on top of Everest, if you aren't doing anything but standing around. It is very hard to exert yourself, however, without an adequate supply of oxygen. 3. The higher you get, the "thinner" the air and the less oxygen. Taking in oxygen is the basic purpose of breathing in the first place. 4, There are now devices and techniques which can help climbers breathe without the need for "bottled" oxygen. For example, anyone planning to climb Everest these days is likely to spend several weeks at altitude beforehand, to give their body time to adapt (like producing extra red blood cells which can then absorb oxygen).
Tim Macartney-Snape reached the summit of Mount Everest on the 3rd October 1984 without the use of artifical oxygen.
Climbers use bottled oxygen on Mount Everest to help them breathe more easily because the higher you climb the less oxygen there is. At the summit of Mount Everest there is approximately 33% of the oxygen that is available at sea level.

At the summit of Mount Everest there is approximately only 33% of the oxygen that is available at sea level.The higher you climb any mountain the less oxygen there is to breathe. This is why climbers carry oxygen cylinders on there backs to help them breathe more easliy.The proportion of Oxygen to other elements is actually very similar to sea level, but the total amount of air or atmosphere is only about one-third that of sea-level, so there is about one-third as much oxygen as there is at sea level.
they died a very horrible death
It is harder to breathe on the summit of Mount Everest than at sea level due to the lack of oxygen. The higher you climb upwards the less oxygen there is, you enter the death zone where the thin air is.
The first to reach the summit of Mount Everest without artificial oxygen were Reinhold Messner and Peter Habler on the 8th May 1978.
Reinhold Messner made the first solo ascent of Everest in 1980. He also climbed without the use of supplemental oxygen.
The higher you climb the less oxygen there is. At the summit of Mount Everest there is approximately 33% of the oxygen that is available at sea level. That is why climbers use bottled oxygen on Mount Everest and other high altitude mountains to help them breathe more easily.
