Does anyone know how the Vytec calculates this?

Because if I take the change in cylinder pressure and either the max or ave depth, and duration, I don't get the same answers, eg

Breathing Rate (litres per min)= Cyl Vol * Cyl DP / Abs P (ave Depth) / duration


Cheers, Paul

How big a difference are you getting on the diff results? Breathing rate ............ is that the same as SAC?

Due to ADD I didn't check your formula!

Do you have any dive statistics to give? I have a little SS I created and I'd love to see how far I am out from the 'real figure'.

I just Googled ............ do any of these help?

Remember dive tables?
