Basically there are three things they can do: # Acclimatization. By not travelling too fast their bodies will adapt to a certain degree. # By not staying too long above 5000 meters. They make quick attempts at the summit, then back down again. # Many carry oxygen tanks and breathe from masks.
Mountaineers often take oxygen tanks when they climb high mountains such as Everest. The tanks contain oxygen gas that has been compressed into small volume. This can help reduce the effect of atmospheric pressure
Edmund Hillary was the first to reach the summit of Mount Everest in 1953 followed by Tenzing Norgay.
Reconstruction
The effects of changing pressure on the boiling point of a liquid is that the water becomes temperature becomes higher. The boiling point will continue to rise depending on the amount of pressure applied.
Altitude sickness (lack of available oxygen) begins above the altitude of 8,000 feet above sea level. I'm not a "peaker", but I've been above 8k enough to recognize the onset of "oxygen deprivation", as somewhat relative to the "runner's cramps" that plagues long-distance runners.

Edmund Hillary was the first to reach the summit of Mount Everest in 1953, since then around 5,000 people have also reached the summit. The effects it has had on the mountain have been the amount of rubbish/junk that they leave behind.

At best there have been a few dozen people die on Everest, where as there are thousands who will die of organ failure around the world. If you mean to ask are you more likely to die on Everest due to either trauma/exposure to elements or from organ failure (perhaps due to organ failure) then the answer is exposure. Most climbers will die when they get lost in the cold and dark. Others will die falling into crevaces (although that is more rare) and some will experience the effects of high altitudes (low oxygen) and do stupid things like step off of the mountain.
It is the act of cancelling something, counteracting the effects of something. Introducing a 'second thing' to overcome the effects of the 'first'.
Because as height increases, pressure decreases and therefore less temperature is needed to produce the same effects. For example, at sea level, water boils at 100C but on top of Mt Everest, water boils at around 70C.
Experiments can be counterbalanced in order to overcome order effects.
