Re: JohnL needs a little help

Showing your humor impairment again.

A real polymath would be able to manage simple arithmetic. It’s not as though we had ever asked you to manage calculus.

Triox is what? I know of the following breathing gases:

1. Air

2. Nitrox aka Enriched Air: a mixture with >21% of Oxygen, the remainder being substantially Nitrogen. Common blends are 32% Oxygen and 36% Oxygen.

3. Heliox: a mixture of Helium and Oxygen

4. Trimix: a mixture of Helium, Oxygen and Nitrogen.

the choice of which has to do with depth, decompression and oxygen toxicity.

Personally I have used air for almost all of my dives. I prefer to decompress rather than use Nitrox, as I have good air consumption. Anything involving Helium gets expensive: fills go from free (I have an air compressor) to the $40-$60 range.

Triox? What’s that. I hope you don’t mean Ozone. It’s poisonous.
