I recently(monday) had a BSAC nitrox instructor telling me that 13/30 trimix was hypoxic(give the man a biccy) and that any attempt to breathe that mixture at the surface would immeadiately render me unconcious! 10/50 meant I would be dead.
OK so the big yellow blender looks after things and I avoid any severe activity like surface swims...
But I have Skiied at over 3000M, and I dont recall taking it easy. Checking the link I was about on track with my maths, I`ve flogged my guts out at an equivalent of 13%O2, without rendering myself unconcious; more than once.
QED
He was talking bolloks.
Sort off!
