If planning a Altitude dive on Nitrox do you use the theoritical depth to figure out "best mix"? I'm thinking you would, and if so it there a formula to convert theoritical depths back to actual depths for the purpose of EAD, MOD and Max Contingency depth? Any altitude tables I've used are not that precise, there has to be a formula.
For Example:
Planning a 120' ffw dive on Nitrox at an elevation of 2000'
Theoritical depth = 129' (from a table)
PO2 = 1.4
Max. Contigency PO2 = 1.6
Mix = 28%
EAD (Theoritical) = 115'
MOD (Theoritical) = 135'
Max Contigency Depth (Theoritical) = 160'
What would EAD, MOD and Max. Contigency be in actual depth?
Maybe I'm looking at this the wrong way, but the question occured to me last night, based on a dive I did last year (not as deep and on air, got pretty narc'd) that I plan on doing again this year but on Nitrox.
Thanks,
Garrett
