Mountain climbers often use supplemental oxygen at high altitudes where oxygen levels are lower to prevent altitude sickness, improve performance, and reduce the risk of potentially fatal conditions like high-altitude pulmonary edema or cerebral edema. It can help climbers think clearly and maintain physical strength while attempting difficult ascents.

Why is it better to burn fuels in a good supply of oxygen?
Burning fuels in a good supply of oxygen allows for more complete combustion, resulting in more energy released and less harmful byproducts like carbon monoxide and soot. Insufficient oxygen can lead to incomplete combustion, creating more pollutants and reducing energy efficiency.
What is oxygen rich?
"Oxygen rich" means lots of oxygen. If the air in a room is "oxygen rich" things will burn better. "Oxygen poor" means there isn't much and "oxygen starved" means there is none or almost none.
Is oxygen a vasopressor?
No, oxygen is not a vasopressor. Oxygen is a gas that is essential for life and is often used to support respiration in various medical conditions by increasing the levels of oxygen in the blood, but it does not have direct vasoconstrictive effects like vasopressors do.
What percentage of oxygen is required to sustain a fire?
Around 16% oxygen is required to sustain a fire. This level is often referred to as the "minimum oxygen concentration for combustion." Fires can be extinguished by reducing the oxygen level below this threshold.
Is helium oxygen?
No. Helium and oxygen are two different elements.
What is the summit of a mountain?
The summit of a mountain is the highest point or peak of the mountain where the elevation is greatest. It is often a goal for climbers to reach the summit of a mountain as a significant achievement.
What is the highest peak of a mountain called?
The highest peak of a mountain is called the summit. It represents the highest point of elevation on the mountain and is often sought after by climbers and hikers. The term "summit" can also refer to the peak of a mountain range.
Where is the zenith of a mountain?
The zenith of a mountain refers to its highest point or peak. It is the summit where the elevation is at its maximum compared to the surrounding terrain. This apex often provides panoramic views of the landscape below and can be a challenging destination for hikers and climbers.
Why do the climbers on Mount Everest often use breathing apparatus?
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.
Why do the rules change on the top of the mountain?
The rules change on the top of the mountain due to the extreme and unpredictable conditions present at high altitudes. Factors such as weather, terrain, and altitude can significantly alter the risks and challenges climbers face. Additionally, the physical and mental demands of high-altitude environments often require a shift in strategy and decision-making. As a result, climbers must adapt their approach to ensure safety and success.
What are wall climbers called?
Wall climbers are commonly referred to as "rock climbers" when engaging in the sport of climbing natural rock formations or artificial rock walls. In urban contexts, individuals who scale buildings or structures might be called "free climbers" or "urban climbers." Additionally, those who participate in competitive climbing events are often labeled as "competition climbers."
What chamber of the heart is most often the first to fail from increased stress or reduced oxygen supply?
Left ventricle
What is the antonym base of a mountain?
The antonym base of a mountain refers to the lowest point or bottom of the mountain, often called the mountain's foothill or base camp. It is the opposite of the peak or summit of the mountain, which is the highest point. The base of a mountain typically serves as a starting point for climbers or hikers to begin their ascent.
What is a crevasse at the head of a mountain glacier called?
A crevasse at the head of a mountain glacier is called a "bergschrund." This feature typically forms where the glacier begins to separate from the surrounding terrain, often due to differential movement between the glacier and the mountain slope. Bergschrunds can be quite deep and wide, posing challenges for climbers and hikers navigating the glacier.
Where do the climbers sleep?
Climbers typically sleep in various types of accommodations depending on the location and the climb's difficulty. On multi-day expeditions, they often set up tents at designated camps along the route, where they can rest and acclimatize. In some cases, like when climbing popular peaks, climbers may stay in mountain huts or lodges before or after a climb. For technical climbs, they might even sleep on the rock face in specialized hanging gear.
What kind of reaction stops when you cut off it's supply oxygen?
A combustion reaction stops when its supply of oxygen is cut off. Combustion requires oxygen to sustain the chemical process of burning, where a fuel reacts with oxygen to produce heat and light. Without oxygen, the reaction cannot continue, leading to the extinguishing of the flame. This principle is often utilized in fire suppression methods.
Walkers and climbers often carry chocolate explain why?
