Vote for this answer. I'd assume that the amount of each element we breathe in would be similar to the amount in which they are present in our atmosphere, which would mean 78% of it is nitrogen, 21% is oxygen, 0.9% is argon, and so on... When we exhale, however, we probably let out a lot less molecular oxygen and a lot more carbon dioxide (in the form of carbon + oxygen).
Due to some heart and lung conditions, not enough oxygen is able to get into your blood to supply your body. Once your condition has been stabilized by medications, supplemental oxygen is used to correct a low oxygen level. This is a common misconception that many people using oxygen have heard. The air we breathe is 21% oxygen. Most people using oxygen are only receiving a slightly higher percentage (about 28% at 2 lpm). This is just enough to bring your blood oxygen levels back to an adequate level.
