One mountaineer said climbing Everest feels like 'running on a treadmill and breathing through a straw' At sea level, the air contains about 21% oxygen. But at altitudes above 12,000 feet, oxygen levels are 40% lower.

When you go to a high elevation there is less air pressure. The lower air pressure makes air less dense (thinner) and so there is less oxygen in the air you breathe. At the top of Mount Everest there is only ? of the oxygen available as there is at sea level.
However, in general, most people can only survive for a few minutes without oxygen at the summit of Mount Everest. The air pressure at the summit of Mount Everest is only about one-third of what it is at sea level.
Climbers who ascend higher than 26,000 feet on Mount Everest enter the death zone. In this area, oxygen is so limited that the body's cells start to die, and judgment becomes impaired. Climbers may also experience heart attack, stroke, or severe altitude sickness.
War zones aside, the high mountains are the only places on Earth where it is expected and even normal to encounter exposed human remains. And of all the mountains where climbers have lost their lives, Everest likely carries the highest risk of coming across bodies simply because there are so many.
The summits of the world's 14 tallest mountains are all found in what is ominously known as the “death zone,” which is typically identified as 8,000 metres (26,000 feet) above sea level. At these altitudes, the oxygen levels are insufficient to sustain human life for an extended period.
Francys Arsentiev is known as The Sleeping Beauty of Everest. She died on Mount Everest on May 24, 1998, when she descended from the top of the tallest mountain after setting the record of the first American female to climb Everest without oxygen. Francys was an American native, born and raised in Hawaii, Honolulu.
According to the Mayo Clinic, during exposure to frigid temperatures like those on Everest—which can dip to minus 20 Fahrenheit during peak climbing season—at first you're liable to feel a prickling, tingling sensation in your outer extremities.
Well, when you're climbing above 8,000 meters, a lot can go wrong. Acute mountain sickness and exhaustion are believed to be the leading causes of death on the mountain.
Removing bodies is dangerous and costs thousands of dollarsGetting bodies out of the death zone is a hazardous chore. It's expensive and it's risky, and it's incredibly dangerous for the Sherpas, Everest climber Alan Arnette previously told the CBC.
At least 12 people have died, with five more still missing. There are many factors at play in the deaths, including altitude sickness and overcrowding.
As with many things in life, the answer to this question is not so simple. However, climbers can expect to spend anywhere between $32,000 (USD) and $200,000 depending on the type of expedition, what is included in the price, and the level of luxury expected.
Aetiology. Altitude-related cough has traditionally been attributed to the inspiration of the cold, dry air which characterises the high altitude mountain environment [2].
Most of the deaths on Everest have occurred in the death zone, which is above 8,000 meters (26,247 feet) in elevation. At this altitude, the air is thin, and oxygen levels are dangerously low, making it extremely difficult for climbers to breathe and remain conscious.
Nepali tourism official Bigyan Koirala told the news agency it's “almost impossible to rescue climbers at that altitude,” the equivalent of over 20,000 feet. At that altitude, temperatures can dip to negative 30 degrees Celsius (negative 86 degrees Fahrenheit).
