Oxygen affect on the body (1 Viewer)

[musagha]

Hello hello.
What does the different leves of oxygen we breathe in affect our body. If we were to breathe in say 40% oxygen as oppose to 21% what would happen? And in the hospital how do the bottles work? Im sure they dont pump pure oxygen into everyone..

this post isn't really gona help .. but i once heard that we weren't able to breathe in 100% pure oxygen as it's poisonous or something and would kill us .. is this true ?

btw is this for bio ?

Well oxygen's used in respiration.
so I guess
increased oxygen = increased ATP production = increased energy?
but then, even when you breathe normally you don't use up all the oxygen for respiration because you breathe out about 8% oxygen.

I know they have oxygen bars in America, I think having heaps of oxygen gives you a bit of a high.

and I think I do remember something about pure oxygen being bad.

yeh bio it is. So any idea what % that oxygen bar is? Would be interesting to know what % gets people high.
Thanks.

Yes, 100% pure (taut much, sle3pe3bumz? - pure and 100% effectively mean the same thing; and no this is not a pun, but yes, I laud you for your astute learning) is poisonous.
The high concentration of oxygen is pretty much hyperoxia and it damages your cells.

and I think I do remember something about pure oxygen being bad.

Possible 'somethings' include one getting dizzy, nauseous, and start to involuntarily twitch; you could even start to convulse, which is never good if you're in the water, say, diving. Also, lung tissue is damaged to the extent that the damage is irreversible.

Sorry that I have to post again; I can't edit.

musagha, about purity:

Hope it helps.

lol Lucid and your language. I was trying to work out if that was a compliment or an insult so I got a dictionary and looked up the words I didn't understand. x) And I'm pretty sure its a compliment, although correct me if I'm wrong. =D

Yeah I was tossing up between pure and 100% and I was like heck, might as well use both ! ^^ thats called a pleonasm ! ahahah ..

ahah .. and im correct for once in my life ! Suprising ! ^^ & thank you for the comments Lucid. Much appreciated. =]

Thanks to Without Wings for fixing up the double post. As earlier expressed, sorry for any inconvenience.

Indeed, sle3pe3bumz, it was a compliment. Absolutely.

lol Lucid and your language

Yeh... I should 'eschew obfuscation'.
haha XD

thank you for the comments Lucid. Much appreciated. =]

No problems, and thank you. Your comments are also much appreciated.

Pleonasm? You just schooled me, right, ma'am? Or is it taught?

* looks up eschew obfuscation *

ahah ohhhh .. naww i love how you use your language =] it allows me to expand on my vocabulary .. ^^

But yess .. pleonasm .. a word I found in my english booklets one day and never forgot ever again for some weird reason ..

I wish I could have Lucids smartness. ahah .. * admires *

Pure oxygen for extended periods can kill.

 

[musagha]

But how?! ohw can pure oxygen kill thats what im trying to get at.

By composition our atmosphere is 78% Nitrogen and 21% Oxygen and so on ...

House fires can reduce ambent oxygen levels to 17% and this is the limit before we suffocate from lack of oxygen.
Conversely 100% Oxygen can kill because we need a wee bit of Carbon Dioxide.
Hence we are used to 21% Oxygen.

O₂ is a free radical; like other free radicals, it has the proclivity to react with metals to form superoxide, which may attack double-bonds in many organic systems, including the volatile unsaturated fatty acid residues in cells, and perhaps alter and damage DNA.

Sure, the human body has its own defences against such things occuring, but 100% is bound to overpower them.

Here's a link entailing stuff about free radical and the human body:

I don't know what that link is about to be honest.

Aw, thanks. Too bad I can't utilise the same level of English elsewhere; (I fathom that I have a confidence problem and esteem issues).

I wish I could have Lucids smartness. ahah .. * admires *

Bah, as if. I'm not smart; as if I am, or were.
But thanks. =D
