We must remember that N2 was added back into heliox mixes to potentiate HPNS on deep dives (
Atlantis dive series). Most of us have continued to use trimix because it is cheaper but not because it has some advantage.
Although theres also some debate as to the N2 effects supressing the tendency to toxicity (hyper excitation or something, Im a telecomms guy, not a wetware guru).....
...fun all this, isnt it
