Do computers only adjust for nitrox by calculating the EAD and tracking time and depth for that adjustment or are they doing something more complex?
Do they give credit for faster offgassing when using nitrox on ascent and at the safety stop or are they just using air calculations (at EAD) for less accumulation?
I am a nitrox recreational diver so please limit answers to that level.
I like the above question and the interesting and informative answers.
And if I dive really shallow (less than 15 feet) with 40% nitrox, my residual nitrogen would be lower than if I had stayed on the surface because the partial pressure of nitrogen during my dive would be lower than air at sea level. Would the computer remember that and carry that over to my next dive?
I think you'd need higher O2 (less N2) or a shallower depth-10' would do it.
Check my math.
.79 ata N2 at the surface breathing air.
.87 ata N2 at 15 feet breathing 60% N2
(15+33) /33 X .60 = .87
