The amount of oxygen in 100 ml of whole blood is not a set amount, but rather is dependent on many factors. Those factors include the individual's personal "volume of health," the level of activity at any one moment in time and also the environment in which the individual is located. If you were to monitor the O2 content of your blood throughout the day, you would find that the concentration was dynamic and would change in response to your activities and environment. That concentration which may be normal at one level of activity may be abnormal for another - similarly, that O2 level that may be normal at one location may be abnormal at another location. As an example, the oxygen content is a function of the partial pressure of O2 in the air. At sea level, the normal partial pressure value for O2 is about 159 mm Hg. However, if one were to be in, say, Mexico City, the value for O2 is about 122 mm Hg. Therefore, all things being equal, there is an higher O2 content as sea level than in Mexico City. A dynamic equilibrium is established in the blood known as the oxygen-haemoglobin dissociation curve. This curve related the partial pressure of oxygen in the blood with the percent of saturation of oxygen. Looking at a disassociation curve will provide you with an O2 concentration for a particular % saturation.

∙ 8y agoThe air which you inhale is about 21% oxygen by volume. So if you take 100 cm3 (ml) of air, 21% of the air would be oxygen. See: http://chemistry.about.com/od/chemistryfaqs/f/aircomposition.htm

How much percent of oxgyen you breathe?
Typically, the air you breathe is comprised of 18 to 21 percent Oxygen.
What percentage of the air you breathe oxygen?
about 21%
Oxygen composes what percentage of the air we breathe?
21%
What percentage of oxygen do you breath from the air?
100%. All of the oxygen that I breathe comes from the air! The answer that you were probably after, but did not ask, was about the percentage of oxygen in the air that we breathe. The questions may sound similar but they are not the same. The answer is a little over 20%.
Oxygen composes approximately what percentage of air we breathe?
21%
What percentage of oxygen in the air we breathe?
It is around 20%.
What percentage of air we breathe is nitrogen?
78% of the air we breathe is nitrogen. 21% is oxygen, and the other 1% is a mix of other gasses.
What percentage of the air we breathe is nitrogen?
78% of the air we breathe is nitrogen. 21% is oxygen, and the other 1% is a mix of other gasses.
What do breathe in and out?
You breathe in air, which is comprised mostly of nitrogen (though the oxygen is what you're after).The oxygen is absorbed into the blood, and stored in red blood cells, which contain hemoglobin.The oxygen in your lungs is thus replaced mainly by carbon dioxide, which is a metabolic waste product, and this is what you breathe out.
Why is it harder to breathe he higher you go?
Because - the higher up the atmosphere you go - the less oxygen is in the air you breathe. Our bodies need a certain percentage of the air we breathe to be Oxygen - reduce the amount of oxygen in each breath, and it soon affects the body.
What percentage of the air around us is oxygen?
The percentage of oxygen in the atmosphere is 20.75%. The atmosphere has many other elements that we breathe in besides oxygen. Oxygen needs to be present for life on earth.
