Hello medical fans, question included.
I thought about posting this in wannabees section but figured I'd get more professional response here!
The leathal "Critical threshold" altitude is where excatly?
I spoke to a friend who spoke another one of his friends (mountain climber) and he says it's 22.000. Speaking to another chap tells me it's 18.000.
Who's right (Or maybe there's reference material somewhere?)and what does the CAA believe to be correct? (just in case exam answer would be entirely different from real life).
Cheers and stay fit.

Is this what you mean? Time Useful Consciousness There is also a term called 'Death Zone' which I've heard to be 20,000ft, 25,000ft, or 8,000m - so take your pick.

So
I reckon what I meant and I've seen as a question is the "DEATH ZONE". My dilemma is that there doesn't seem to be a solid reference or that some countires believe it to be at different levels.
Trouble is on my exam the options will be: 18.000, 22.000, 20.000, 25.000
Thanks for the trouble though!

In that case it's a stupid question and has no practical relevance to aviation that I can see. But then one could say that about a lot of these CAA questions....
If CAA doesn't indulge in negative marking on these multi guess type questions I'd go for 20,000. Though having spent a miserable night at 19,000ft I'd say from personal experience it was lower

From a practical point of view, 10,000 feet has long been regarded as the height above which pilots need oxygen, with the proviso that the ones that smoke probably need it at around 8,000.
Are the CAA really asking mountaineering questions? Perhaps they could throw in a few questions on technical diving limits!

well, i dug out my my old atpl books and found this:
18.000 feet: hypoxia almost instantly, uncontiousnes within 7min
22.000 feet: no info
25.000 feet: more severe hypoxia, uncontiousnes within 5min
30.000 feet: instant loss of coordination, unc. within 2min
33.000 feet: pure oxygene needed, unc. within 15-25 sec
NOTE: big differences exists between persons and "dayly shape"
