My Rescue manual (took it in 2006). Probably in the DM manual too.I think I read that too about using it if you ran out of O2 but can't remember where. You remember where that was from?

I don’t understand the joke but it sounded funny.Just make sure to inform the crew beforehand so they have a fresh stock
of rotten vegetables to throw at you whilst you are doing all that sucking
1.4 metres ABOVE surface [...] would breathing EAN32 after the dive benefit you in terms ofonoff gassing? Yes, but it would be very, very insignificant
So what your saying is staying in an upper floor at the resort prior to flight home has more benefit
You know what I made a mistake on my calculation on my last post. Breathing EAN32 at the surface gives an EAD being at 0.86 ATA, but that is not 1.4m above sea level. I don't know what altitude that would be, any ways, the point remains, the difference in off gassing would be negligible.
Works well if they've been in the back of the boat breathing diesel exhaust fumes while they chum the water... heck even if it's just a tank of air it will be beneficial.I've heard of captains, DM etc giving a nitrox tank to someone with sea sickness.
It looks like the difference is very slight. I ran two profiles using my dive Excel spreadsheet. You can download the spreadsheet here.
