Due to the immense buffering effect of the atmosphere the oxygen levels out of doors are always within a few factional percentage points od 21%. Possible exemptions might be directly in industrial exhaust plumes, downwind of very large fires or in areas with volcanic vents on still days.

What is the average oxygen level in the air at 5000 ft?
The oxygen content of air at any altitude is always about 21%
Why does the level of oxygen decreases on high mountain?
The level of oxygen decreases on high mountains because it is slightly havier than air.
How oxygen level is maintained in air?
Plants produce oxygen by photosynthesis. The Earth's oxygen comes almost entirely from plant life. Of the plants supplying oxygen over haf are alagae in the Earth's oceans. As to why the oxygen level is maintained at about 21%, this is due to feedback loops in the oxygen cycle involving air and water temperaues, carbon dioxide availability, sunlight and ultraviolet light.
How the amount of oxygen in the atmosphere affects respiration?
The lower the percentage of oxygen air contains, the more frequent a breath must be taken in order to maintain the blood oxygen level at an acceptable level.
What elevation increases oxygen content?
It is at sea level. The higher you climb from sea level, to reach the summit of Mount Everest (for example), the less oxygen is in the very thin air. This is why the majority of climbers of Mount Everest have to carry oxygen cylinders. Someone occasionally achieves the summit without oxygen tanks! Therefore, the higher the altitude, the thinner the oxygen in the air.
What level inhaled oxygen?
21% of the air we inhale is oxygen
What is the average oxygen level in air at sea level?
21%
What happens to oxygen level at high altitudes?
The oxygen level remains about the same, but the density of the air is reduced.
What is the average oxygen level in the air at 5000 ft?
The oxygen content of air at any altitude is always about 21%
What's the percentage of oxygen in air at sea level to 4 decimal places?
2.66666666667 is the decimal of oxygen in the air
How much oxygen in air?
Oxygen is it's own element. Air is a combination of elements. That question is not even a sentence, but I think your answer is Air is 19% Oxygen at sea level.
Why does the level of oxygen decreases on high mountain?
The level of oxygen decreases on high mountains because it is slightly havier than air.
What is the Percentage of oxygen in the air in Denver?
Sea level oxygen is around 21% and Denver has about 18% available oxygen.
How oxygen level is maintained in air?
Plants produce oxygen by photosynthesis. The Earth's oxygen comes almost entirely from plant life. Of the plants supplying oxygen over haf are alagae in the Earth's oceans. As to why the oxygen level is maintained at about 21%, this is due to feedback loops in the oxygen cycle involving air and water temperaues, carbon dioxide availability, sunlight and ultraviolet light.
Does ocean water have higher levels of oxygen than air?
I would say the air has the highest level of oxygen but it depends how high up you are.
Can a person live on 63 percent oxygen level?
If you are speaking in terms of blood oxygen saturation, then no, life is not sustainable at this level. Normal adult blood oxygen saturation is 96%-100% The air around us contains 21% oxygen at sea level. So speaking in terms of 63% oxygen in the air then survival would not be a problem as this would be triple the amount you currently breathe.
How the amount of oxygen in the atmosphere affects respiration?
The lower the percentage of oxygen air contains, the more frequent a breath must be taken in order to maintain the blood oxygen level at an acceptable level.
