This is known as the bends. You can use nitrogen but that will increase the risk after around 150 ft under the sea. That is why it is preferred to use Helium.

What? No, that's completely wrong.

The bends is caused from sudden pressure changes that cause gases(mainly nitrogen as it's ~70% of the atmosphere) to come out of your blood in bubbles.

Decompression sickness has nothing to do with oxygen poisoning.

Your wrong. He made a simply correct post.

from wiki

Scuba divers and submariners also rely on artificially-delivered O2, but most often use normal pressure, and/or mixtures of oxygen and air. Pure or nearly pure O2 use in diving at higher-than-sea-level pressures is usually limited to rebreather, decompression, or emergency treatment use at relatively shallow depths (~ 6 meters depth, or less).[77][78] Deeper diving requires significant dilution of O2 with other gases, such as nitrogen or helium, to help prevent oxygen toxicity.[77]

OK, tell me why he was correct and why I'm wrong.

I don't believe pressure has anything to do with how much oxygen there is compared to other gases, as all gases can be regulated.
