Normoxic is a gas mix with the same level of oxygen as found in air, (normal level of oxygen). Hypoxic is a gas mix with a lower level of oxygen than found in air.

It has 21%oxygen, but some of the nitrogen is replaced with helium to reduce narcosis at depth. Hypoxic Trimix is used to dive deeper than safely possible on Normoxic mixes.
