Hey, I would like to ask, what would happen to human beings if the oxygen level started to decrease?
By decrease I mean systematically, but 0,5% from the basic 21%. I am aware that the oxygen level is always the same, though the air pressure makes it
By decrease I mean systematically, but 0,5% from the basic 21%. I am aware that the oxygen level is always the same, though the air pressure makes it a little bit more diluted on higher attitudes, and our kidneys, if my memory serves, start to produce more erythropoietin then, untill the level of erythrocytes in our blood system reaches the proper level to transport more oxygen molecules. But, I am curious, what effects would lower and lower level of oxygen force on our bodies, and by what percentage drop would we actually die?
Thank You.

or:if that happened we would probably get very weak, and eventually die, because of lack of oxygen, but i really dont think that it will happen anyway. but i understand you probably already know that...this question is a bit over my intelligence level. sorry
or:http://www.adlers.com.au/images/oxygengraph.gifThe above linked graph shows what happens to the oxygen level as you increase altitude. Normally people have difficulty breathing and making any sustained effort at levels above 2km without oxygen assistance or unless they have become acclimatised to it.The result of acclimatisation is to increase the number of red blood cells in the blood, as this is what carries oxygen to the organs and muscles, especially the brain. A general decrease of only 0.5 % would, have little effect, apart from raising the red blood cell count a little.
