Is helium poisonous if you inhale too much?

Answer 1

Yes, a single deep breath of pure helium will drive all the oxygen out of your lungs and you will pass out. After that you will probably be breathing air again so you will recover, but remember, the first result of reduced oxygen to the brain is brain damage.
yes and no.............

Inhaling Helium in small amounts is safe enough, such as taking a breath of helium from a balloon to change your voice, but even doing this too many times in a row can cause headaches, disorientation or lightheadedness, since helium deprives your body of oxygen...and taking a single deep breath of pure helium can also lead to unconsciousness, and maybe death by asphyxiation.

Remember, the first result of reduced oxygen to the brain is brain damage. The second result is death.

But other than that and the voice changes helium is basically harmless in small amounts...Helium is also mixed with other gases such as oxygen, compressed air etc for diving purposes...

No. Just breath every once and a while. There is helium in the air we breathe and we're just fine. So after everytime you suck down some helium from a balloon or whatever, just take a deep breath so your brain gets the oxygen it needs.

Yes, your inner organs will collapse and then blood will stop rushing to your brain any you will die in a matter of hours.
you're supposed to be breathing oxygen instead, so if you breathe too much helium, you won't get enough oxygen
yes.
Yes. It kills brain cells and it's to high of a concentration for your body to handle. People were made for oxygen.... not helium. It also leads to brain damage.

------------------------

Breathing in too much helium can displace oxygen that you need and you may get dizzy while you're doing it.

If you breathe in just PURE helium, that can lead to suffocation, because our bodies need oxygen.

Inhaling continuous breaths of helium one after another starves the body of oxygen. A person will eventually pass out, and perhaps even worse. At most, inhaling once or twice from a helium balloon, separated by deep inhalations of air, will be a way to prevent the harm. So, bottom line is that it's okay to inhale a bit of helium for fun but you have to pay attention to how much you inhale so it won't harm your health.

Yes, breathing helium is harmful if that's all you're breathing. You need oxygen to live, and without O2 in the gas you breathe, you will lose consciousness and you can asphyxiate. Asphyxiation leads to death. Helium is used in what is called mixed gas breathing apparatus for use in deep diving. In this situation, the gas mixture is almost all helium, and oxygen is regulated in a way that the partial pressure of oxygen is "correct" and the diver gets enough but not too much O2 and can dive safely.
It isn't a bad thing to do....we had helium balloons sink then i sucked the helium out....make sure to suck in oxygen also, or else you will probably die or something. Helium makes your voice sound weird and awesome!! I love it but it isn't that good for me. It's fun, but it's not the best. Don't do it that often. I'd use helium balloons if I were you, not helium tanks. (:
