Air backup for a nitrox dive?

[caruso]

So yes their bickering killed them thanks.

A collapsing wall and entrapment which led to an overextended stay at depth which led to narcosis that likely exacerbated an already fatal situation welcome

Hey caruso you gotta take a look at Chowdhurys dice with DCS

A far more relevant situation applicable to dives being conducted everyday
by everyday divers

Pokes big holes in the big joke of going for a chopper ride to the chamber
and the doctor will kiss it better

and you really should hurry and read the book before you come on here quoting more wrong stuff
and putting your wrong take on it

an overextended stay at depth which led to narcosis

at 230 feet an overextended stay at depth which LED to narcosis

Mate there may well be a few other books for you to read as well

Say I have Spare Air (the air model, not nitrox) and I have an OOA situation on a nitrox dive. Am I correct in assuming that it's safe to switch to the 20.9% backup for my ascent? I can't wrap my head around it at the moment.

Yes, it is correct!

I already read all the good ones.

I think they're still diving.

you are by the letter of the statement correct but not in practice....... you are not trying to enjoy diving you are trying to escape from diving just as you would from a burning building, and just like teh building you may literally be renting a space in that building but when it is on fire you are in escape mode its no longer where you live.

They would still be diving but not enjoying it.
