It refers to altitudes above a certain point where the amount of oxygen is insufficient to sustain human life for an extended time span. However we can only survive for minutes without oxygen.

The percentage of oxygen is the same at sea level as it is at high altitudes which is roughly 21 percent.
. Atmospheric pressure and inspired oxygen pressure fall. Increased altitude means reduced atmospheric pressure so each breath contains less and less oxygen molecules. Although air contains 209 oxygen at all altitudes lower air pressure at high.
There are many reasonable answers here. At the top of Everest the tallest mountain the density of air is only about 13 of the value at sea-level. High altitude to a physiologist starts around 5000ft the altitude where the body senses changes in the oxygen level and starts to respond by increasing breathing.
So there is only about a third as much of any component in the air. Thats like climbing up stairs and only getting 1 out of every 3. Humans can survive for weeks without food.
Below is an altitude oxygen chart that extrapolates oxygen percentages to real altitude which you can use in conjunction with Hypoxico systems. The body has to strain to get oxygen through deeper and quicker. Air also contains a variable amount of water vapor on average around 1 at sea.
While the percentage of. Ski resorts in Colorado. Answer 1 of 7.
The amount of air molecules in the air is not as relavent as the partial pressure of the. Air in Earths atmosphere contains about 21 percent oxygen 78 percent nitrogen and one percent other gases such as argon carbon dioxide neon helium and hydrogen. This is referred to as the Fraction of Inspired Oxygen or FiO2.
As oxygen is 21 of dry air the inspired oxygen pressure is 021 10063196 kPa at sea level. This chart will help you find oxygen levels. Air contains about 78 nitrogen and 21 oxygen independent of altitude up to 100 km.
Use the table below to see how the effective amount of oxygen in the air varies at different altitudes. However because air molecules at high altitudes are more dispersed each breath. However Id like to add a significant point.
Altitude and Oxygen. Shouldnt the concentration of nitrogen increase with higher altitudes. This corresponds to 7551 nitrogen 2314 oxygen 128 argon and 006 carbon dioxide by mass.
At what altitude is there no oxygen. At the summit of Mount Everest at 8850 metres there will be approximately 33 of the oxygen that is available at sea level. The air we breathe in has the same amount of oxygen about 21 percent or just 021 at all altitudes.
