Oxygen toxicity is an iatrogenic illness caused by exposure to high FIO2 during oxygen therapy. Oxygen saturation should be monitored in patients receiving supplemental O2. As the oxygen gets metabolized, some molecules convert to superoxide anions known as hydroxyl radicals, which are human tissue toxic. The resulting pathophysiological changes at the alveolar level result in decreases in lung compliance, diffusing capacity, and PaO2 levels. Central nervous system (CNS) toxicity can occur with exposure to high partial pressures of oxygen. Acute changes in the lungs resulting from oxygen toxicity consist of alveolar and interstitial edema, alveolar hemorrhages, and proteinaceous exudates. Further prolonged exposure to oxygen leads to a proliferative phase, which includes the proliferation of type II epithelial cells and fibroblasts, followed by collagen deposits. Exposure to FIO2s greater than 0.60 for as little as 24 to 48 hours can lead to severe irreversible pulmonary fibrosis.[6][7]
That’s why breathing pure oxygen is bad idea
everyday
Next.
If you think that is bad, just wait til you learn about Dihydrogen Monoxide. That shit kills.
100% of the people who drink dihydrogen monoxide eventually end up dying. Shit’s dangerous
Stop downplaying it, call it by its most descriptive name:
Hydric acid
Oxygen is one of the most reactive gases. It can burn iron at 100°C.
It can burn diamond at 720 °C, what do you think it’ll do to soft tissue over the course of an entire lifetime. Things helping aerobic life survive are
a) partially consisting of partially oxidized polymers in the form of carbohydrates (remember, the only thing that cannot burn is what has already been burned);
b) oxygen’s peculiar, natural triplet state which greatly slows down its kinetics compared e.g. to its horrible relative, ozone.
I read some interesting comment before (so take it with a grain of salt) where someone who knew a bit of chemistry said, ‘in a way we actually are damaged by the oxygen we breathe’. Details foggy but they mentioned that’s kinda what free radicals are about, that we are burning up on a cellular level, albiet over the course of our lifetimes
Yeah it’s why we have antioxidants. The idea is oxygen is constantly stealing electrons from nearby molecules and antioxidants help replace those electrons.
Life is just a constant form of slow death. Up until your body simply can’t replace the old cells fast enough anymore.
Oh good i remembered it roughly right. you happen to have a good layman-friendly source just laying around? id love a refresher. I don’t usually outsource my searches but i mustve used the wrong terms earlier, cuz i keep getting bunk ass health scam sites
This may be a good source for it: https://www.goodreads.com/book/show/25663961-how-not-to-die
The book is about food, but mostly it talks about oxidation of the body and how various foods affect that, because that seems to be the main factor for aging and other degradation of the body. (TL;dr: eat a lot of broccoli)
I’m not an expert though, so cannot judge how accurately the science is presented
Thanks, I’m not either so this will help me a ton. Thanks!
This website I found has a decent summary: https://en.wikipedia.org/wiki/Oxidative_stress
Hey, tyvm :)
It’s true. The medical field over the last few decades has curbed when to give patients high flow concentrated oxygen for this reason.
So I know it’s a joke, but isn’t this why dietary antioxidants are good for you, is because they literally help inhibit the oxidation of your body?
Also pure oxygen is bad long term
Oxygen ravages electrons all day at the end of the electron transport chain and nobody bats an eye, but you steal one pair off some DNA and everybody loses their minds!
It’s true my friend works with it and their hair went blue
Makes me think of the DHMO awareness campaign
HOW DARE YOU BAD MOUTH RUST LIKE THAT! Rust is natural, and isn’t anything bad. Let your body rust, and accept it’s warm embrace.
!/s!<
Have you tried doing it in Rust?
Oxygen is one of the key components of dihydrogen monoxide, and we all know how dangerous that stuff can be.
We joke but oxygen is a caustic poison and when it came on the scene, evolution practically had to start over
there are three constants in life.
taxes, rule 34, And oxidation.
the fact that I made a rule 34 joke about this without even seeing this comment is so great
great minds think alike, or something.
Wait until OP learns about dihydrogen-monoxide.
I thought this will somehow relate to rust programming language
What oxygen does to your lungs is what Rust does to your brain
