How long does it take for helium to make you unconscious?

The result is 0.22 seconds. Since lungs are not a rigid container, actual time to reach 1.7 psi may be slightly longer than 0.22 seconds.

What happens when you suck in helium from a balloon?

If you inhale helium from a balloon, you get a squeaky voice. You might also get light-headed because you’re breathing in pure helium gas rather than oxygen-containing air. This can lead to hypoxia or low oxygen. Helium is non-toxic and you’ll start breathing normal air as soon as you move away from the balloon.

Why does your voice get higher when you inhale helium?

That’s because helium is so much lighter than air. When sound waves speed up but their frequency stays the same, each wave stretches out. It’s a gas that is much heavier than air, so when it is inhaled, it shortens sound waves so the lower tones in the voice are amplified and the higher ones fade out.

Can You Suffocate from breathing helium?
