I agree with gary g, the O2 setup in this (rather old) report was probably of the "respiratory disease" type, e.g. 2 liter/min with this nose thingy.
With a proper O2 setup I abort a beginning attack within 5 to 10 minutes, never exceeding a Kip #4.
In the current cycle I had to try the cold air twice: At the start of the cycle in February (I ordered O2 the following morning) and a fortnight ago when I ran out of O2 on Sunday evening. On both occasions the temperature was a few degrees above freezing. I did a 3 km march and after 20 minutes the attack ended, but going 2 notches higher on the Kip scale.
However, I suspect it was not so much the cold air than the hyperventilation that helped. At least, I had no pain in my right leg, which with 'normal' walking starts to hurt after only 100m, due to circulation problems there. This indicates that a lot more O2 circulated in my blood during the CH marches.
So I suspect hyperventilation on cold air is marginally better than on normal air.
