| Hi all, and thanks for your replies!
Phoenix - Thanks for that link, that PDF was most interesting. (And nice to meet you at Wraysbury too).
schford - I thought I had a reasonable grasp of how partial pressures 'worked' but I realise now that my understanding is a bit shakier than I thought. I understood the way things worked dealing with fractions of the loop, but not quantities. So, I think that gives me a reasonable idea of why the scrubbers are less effective at depth. Thanks!
Drmike - read your story re the near miss, most interesting.
Turbanator - I'll see if I can pick up that book. I'm not likely to get a 'breather in the near future, but want to make sure that when I finally do make the jump, I have as good a grounding as possible in the way things work as far as the theory goes.
Janos: I see what you mean about the diluent/BOV issue - noted!
Padowan - another thing I'd missed. The raised WOB at depth causing a greater production of CO2 also presumably contributes to the shortened scrubber life span.
In general, thanks also everyone for the info about how you manage hypoxic diluents. It's useful to know that there are plenty more than one answer for these things!
Thanks again,
David
