RE: [PSUBS-MAILIST] sofnolime

Yes, in the life support paper on PSUBS there is a reference to Simon Fraser University research that boiled down to a very simple bottom line... 1 pound of absorbent lasts 4 person hours. Its much more complex than that, with things like temperature and humidity influencing the number, but that was reportedly a consistent finding. The study I think applied to Sodasorb, so I'm not sure if there is a difference with Sofnolime.

Also refer to ABS rules as far as how many hours are required overall -- generally 72hrs.

rgds,

Is there a formula to calculate the amount of absorbent you need? 
Air space + number of people + length of dive = amount of absorbent
