how come the helium gas is dangerous for human beings???

Answer 1

Who said helium is dangerous ?
It is used for breathing-gas, mixed with oxygen, by deep sea divers.
Not dangerous at all.

Answer 2

Simply because of the fact that humans need oxygen in order to make new red blood cells so that their brains can function properly. Helium gas is dangerous in the same ways that other gasses are dangerous.

Answer 3

the rationalization deep sea divers and astronauts breath a blend of helium and air is to help prevent bends -- it truly is what occurs at the same time as air bubbles assemble on your joints and different places in the body once you decompress. that is really painful, might want to be deadly, and in case you reside to inform the tale, you would possibly want to be crippled for existence. So the astronauts and deep sea divers have a reason to respire helium. they don't breathe organic helium through the way, and it would not bypass on for weeks. it really is element of the decompression or the re-get admission to procedure. there is a few helium in the air we breathe on a daily basis. Minute quantities, even with the undeniable fact that that is there. even with the undeniable fact that the human mind isn't designed to handle rather a lot of helium. There have not been adequate learn carried out on the end results of helium on the mind to both make sure or refute the little old women in the back of the counter, yet in my opinion, i might want to hesitate to ingest something that wasn't necessary and noticeably something that had the flair for deleterious effects. definite, it sounds humorous once you breathe it and commence speaking like Donald Duck, even with the undeniable fact that it would not be so humorous in case you began to believe you've been Donald Duck.

Answer 4

we normally breathe a mix of oxygen (21%) Nitrogen (78%) y other trace gasses, when you change that concentration and inhale helium instead (100%) then you have n oxygen gas to carry on with the normal physiology of your body, that means that your body starves for oxygen (hypoxia) and hence can die
it depends how long you inhale helium (a couple who died from crawling into a giant balloon filled with helium)
the helium in a normal party balloon can most likely not cause hypoxemia but damage your vocal cords as it passes trough them (due to the difference in temperature and physics of the gas: different from oxygen)

Answer 5

Because your body needs oxygen not helium. When you breathe in the helium you can kill brain cells.

Answer 6

Not always !!!!!, the mixture of Oxygen with Helium- HELIOX is used for the Treatment of Acute Asthma.

Answer 7

it constricts the vocal chords and the lerinex. you lose a lot of oxygen and you sound rediculous. Shall i continue?
