Inhaling Oxygen before launch? Sounds like a very good idea, I had toyed with similar but don't have access to the bottled stuff, so I'd have to crack my own via electrolysis, store it in bags then have a big suck. Just haven't had time to try this yet.
Lung damage from pure 100% oxygen ? True if you breathe it for hours, but I doubt one or two
lung fulls are going to do much damage, particularly if followed by a period of decreased
respiration. Hyperbaric oxygen is delivered under pressure, in a special chamber, so unless
you plan to invest in such a chamber, hyperbaric conditions do not apply for most of us.
Another suggestion might be to dose up with Q10 for several days beforehand.
Oxygen is the slow path to ATP, which is really the energy molecule for the cells, and apparently Q10 can increase mitochondria efficiency and increase production/storage of ATP. It has been effective for some types of athletic performance, I believe mostly sprint sports?
I do agree that cellular energy stores get rapidly depleted by spice, leaving one drained afterwards - and diet / supplements / exercise are probably a counter for some of this.
One saftey comment I think worth mentioning, is the flammable nature of 02 - often lighters / smoking and 02 do not mix well, 02 tends to make everything burn - really really well. (funny bout that - oxidisation...)
I have heard fairly reliable stories of people literally catching
on fire - because they smoked with high % of oxygen in lungs / around them,
so if you are mucking around with pure 02 - BE CAREFUL WITH NAKED FLAMES !!!
Still - IMHO - there is merit in researching ways to boost cellular energy
stores prior to hyperspace travel, and a few breaths of 100% O2 might do the trick.
Perhaps it would be better to do the deep 02 breaths, then do 1 or 2 breaths of
normal air - so that the spice is not going into 100% 02 in your lungs.
Otherwise you might get a lot of oxidation of the spice, before it even
gets into your bloodstream?
Anyway - Good work that traveller...
