Question

What elevation do you have to reach, when you start getting sick?

Answer 1

It's in your textbook. Look it up.

Answer 2

it depends on the person.

Answer 3

About 20 per cent of people experience mild symptoms at altitudes between 2200 and 2500m above sea level.

The incidence of altitude sickness, which varies from one individual to another, is directly related to the rate of ascent. It is also significantly related to how long a person stays at that height.

The risk of getting altitude sickness in areas such as Nepal and the Andes mountains, where tourist regions can be as high as 3000-4000m, is very real. Each year, out of 50,000 travellers to Nepal, there are at least seven altitude-related deaths. The death rate is about 4 per cent for trips to peaks above 7000m.

Answer 4

- Although it does depend on person to person, the airline industry thinks of 8000' (2438.5 meters) as the altitude that most people can tolerate without too much discomfort. They pressurize their planes so that the air pressure is equivalent to altitude of 8000'.

- New construction materials may make it possible to economically build airplanes that can be pressurized to an alititude of 6000' so that passengers are more comfortable. However, with the cost of fuel being so high, it is unlikely to become widespread design criterion. Business jets maintain a much higher cabin pressure than commercial jets.

- I've been on military planes that are pressurized to 10,000 feet (to save money) and they are significantly more uncomfortable. You feel woozier and you get much more dehydrated.

- Arapahoe Basin is a ski resort in Colorado with a top altitude of 13,000 feet. It is extremely difficult to ski with so little oxygen. I've tried it but it is very uncomfortable. It is the first ski resort in North America since it was relatively easy to build a resort so far above the tree-line. Most of the clients are locals who are living at a fairly high altitude and are already acclimatized.

- The peak of Mt. Whitney (the highest point in the continental US is 14,494 ft. or (4420.7 m) . The trailhead is at 8,365' 21.4 miles round trip. Most people start off at 2 or 3 AM and try to summit and return before midnight. Good hikers can do it all in daylight.

-  Base Camp at Everest is 17,600 feet. People must remain at base camp for a significant time, getting used to that altitude before they attempt to climb higher.

-  The "death zone" is usually considered 23,000 feet to 26,000 feet. At this altitude no human body can acclimatize and you can only survive temporarily. Spiders have been observed to live permanently at 22,000 feet and it is presumed to be the maximum altitude that an animal can live permanently.

Answer 5

it depends on the person

Answer 6

Depends from where you start out... people live at all levels so Normal is variable.

Answer 7

like they said it varies from person to person like my brother is about 50 feet lol ive been up 10000 feet skydiving so yeah

Answer 8

26,169'-1/16th". This is known as 'the line of death'. Anything above this elevation is like stepping into the abyss. It has to do with the nature of our red blood cell's capacity to obtain and distribute oxygen in a manner sufficient to sustain life.

Answer 9

Depends and varies from person to person.

Answer 10

As a light aircraft pilot, I am allowed to fly up to 12,000 feet for half an hour without oxygen supply. Longer or higher, I need oxygen.

The typical symptoms of hypoxia (lack of oxygen) are disorientation and euphoria. The latter is dangerous because you may feel good and don't realize what is happening. At night, perspective vision is often altered even at altitude of say 10,000 feet as I have experienced myself.
