Hey, doesn't "normoxic" mean regular air?

Just what the heck is normoxic trimix training, anyway?
It means the same fO2 as air. Technically, Air would be Normoxic Trimix with 0% He, but that's not going to be how most use the term. Normoxic Trimix is "just" replacing some of the Nitrogen with Helium.

Normoxic trimix means a mixture of trimix with 19 percent oxygen or more. This is compared to hypoxic (also known as full trimix) which is required below 200 ft. to make sure that you don't have oxygen toxicity issues on your bottom mix. The O2 levels in hypoxic mixes are below 19 percent and many require the diver to breathe a mix of nitrox to perform their descent to a certain level lest they get light headed on the way down due to a lack of oxygen.

Normoxic trimix is used to dive to depths of up to 200 ft. Also, it is combined with a technical diver class which covers the use of any decompression gas and any amount/level of decompression that I take down enough decompression gas to perform. By the end of the summer, I plan to be diving some deep wrecks and I want to be able to do it safely. I don't like to use deep air.

By the way, I like Rob's explanation better.
