@ief015(View Post) Dumb kids on the forums eh? Say things that aren't even true. @disturbed666 Atleast do research, this is the internets you know.... you have google in reach. EDIT: Nope, absolutely pure.
@ief015 ok i will search on wikipedia http://en.wikipedia.org/wiki/Oxygen_mask here you can read it isn't pure oxygen just a slightly higher amount for breathing and i know that co2 would kill you in high amounts but is still needed a bit to trigger the brain to breath
and of course oxygen tanks contain oxygen but oxygen for medical purposes is not PURE oxygen.
@disturbed666(View Post) If they used only the oxygen in oxygen tanks to be inhaled, it will be gone much faster. So they mix the oxygen tank with the air on the outside, making it just a higher amount of O2. That's what the oxygen MASK does.
@disturbed666(View Post) It depends. The reason why we exhale is to get rid of the CO2 in our lungs to make way for new oxygen. CO2 is a poison that humans create after breathing oxygen.
@ief015(View Post) yes i know but there stands that if you would breath pure oxygen it could harm you and that was my point.
Oxygen in these higher percentages is classified as a drug with too much oxygen being potentially harmful to a patients health resulting in oxygen dependence, over time, and in extreme circumstances patient blindness. For these reasons oxygen therapy is closely monitored
It will not harm you if you inhale the same amount of oxygen or slowly less oxygen over time. The reason we can breathe the air outside is because our body is used to it. It is only harmful in the sense that your brain needs the oxygen.
