Hey Harry,
Well Ive been busy digging through my papers trying to find where this came from with no sucess - indeed quite the contrary as Ive found I have lots of referances to exactly the opposite being the case! (He as an inert gas reduces time to tox compared to N2 as inert gas!) lol. Frankly Im starting to think I was talking bollock5

re: ppHE contribution to toxing - however it doesnt change my overall position on unecessarily high ppo2s on deep dives
Damn I got something wrong!! - guess theres a 1st time for everything
