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).
Air contains 20.95% oxygen. At 11,900 m (39,000 ft), breathing pure oxygen through an unsealed face mask, one is breathing the same partial pressure of oxygen as one would experience with regular air at around 3,600 m (11,800 ft) above sea level.
