Hi,
> Hi Robert could you explain better SCR mode?
I am a bit in a rush, so only briefly:
I discussed this a bit some time ago with John Kendall (one of the GUE instructors and SCR divers).
It should be safe to only use the steady state solution of the time dependent O2 content (as it is reached very quickly).
I have a piece of paper with some calculations and a boxed equation that says
ppO2_ss = ppO2_in - (1 -fO2_in) * O2consumption / (SAC * r)
where O2consumption is what the body metabolizes per minute (in l/min) and SAC is the surface air consumption (in l/min) and r is the ration of droped gas in the rebreather. Those three parameters should be gotten from the preferences/UI somewhere.
Does that help?
Best
Robert
