Oxygen content decreases at what rate with increased elevation?

The relationship between elevation and atmospheric oxygen content is not a simple linear one. It's actually exponential with multiple variables. The oxygen concentration as a function of elevation can be calculated from the Barometric formula: P = P0 exp(-M g z / RT) where P0 = sea level Pressure (~1000 hPa), M = mass of 1 mol of air (~0.029 kg mol-1), g = gravity (9.8 ms-2), z = elevation (m), R = gas constant (8.314 J K-1 mol-1) and T = temperature (K). However, for the first 2 km (~6500 ft) above sea level the relationship can be approximated as linear. In this case, at a constant temperature, the rate at which oxygen decreases with elevation is about 10% per km.

How does oxygen content change with altitude?
The density of air decreases with altitude, so the ratio of oxygen in the air stays the same, but the amount of gases in your lungs decrease.
What happens to the oxygen level at high altitudes?
the oxygen level decreases
Does elevation effect the amount of oxygen?
Yes
What is the relationship of oxygen density to altitude?
As the altitude increases, the density of oxygen decreases.
How can pollution affect the level of oxygen in water?
The concentration of oxygen in waters decreases.
Is dissolved oxygen increased by turbulence?
yes. if anything stirs up the water (turbulence) the oxygen content will be increased.
Do fires have an elevation limit?
I have no idea, but I would assume so since the oxygen level decreases with altitude.
When water temperature increases what will the dissolved oxygen content do?
The amount of dissolved oxygen decreases when water temperature increases. Warm water is unable to dissolve as much oxygen gas.
Does the content of oxygen in water decreases when water is boiled for too long?
When you boil water the oxygen content is reduced to zero. (All gasses are driven out,) Boiling it longer doesn't have much effect.
Atmospheric oxygen increased after the evolution of photosynthetic prokaryotes?
There is an increased amount of oxygen after completion of the photosynthetic process.
How does oxygen content change with altitude?
The density of air decreases with altitude, so the ratio of oxygen in the air stays the same, but the amount of gases in your lungs decrease.
Which major physical change could be attributed to photosynthesis?
Photosynthesis drastically increased the oxygen content of the atmosphere.
The oxygen content in the atmosphere of the early Earth is thought to have increased significantly once which of these developed?
green plants / algae
What effect does elevation have on average temperature?
As you rise, Oxygen decreases. That's why you need a oxygen mask to provide you with sustainance while in high altitudes. The air molecules are further apart and move much slower, there for making the temperture cold.
When elevation increases oxygen content?
The following changes are average changes, which means there might be exceptions more or less as we rise upward. But in general as elevation increases, on average: Temperature decreases Atm pressure decreases Wind velocity increases Gamma radiation increases Overhead turns black More and more stars are seen Shape of the planet as a sphere becomes obvious
Does resting help for hemorrhoids?
Activity increased vasodilation because increased activity requires a better blood supply. Resting decreases the dilation of the blood vessels because less blood is needed for oxygen and energy.
What is the pulmonary response to high altitude?
Normally at sea level, atmospheric pressure equals pulmonary pressure. As we move towards high altitudes, the atmospheric pressure decreases. Hence we need to put some effort for respiration at high altitudes. As altitude increases that oxygen content in the air decreases. In the lunges there is a reflex that guides blood flow to lung areas taht are ventilated. When the oxygen content is reduced more small blood vessels are closed due to this reflex. This results in increased blodpressure in the lung vessels. The higher the pressure the more fluid is pressed (filtered) out, and this results in lung edema or water in the lungs. Slow ascent allows for the lungs to adapt, to some extent, to a lower oxygen content, which is why slow ascent is favourable.
