I was informed that the increase in breathing resistance with used sorb though was negligable compared to the work of breathing resistance caused by elbows and the gas changing direction and the like..

That is to say when you measure the Work of Breathing for the whole loop not just the scrubber the impact of the used material is minimal as the work of breathing caused by the scrubber is minimal compared to that caused by gas changing direction in the loop, one way valves etc.

Have you tested the impact with the whole loop or just the scrubber - if so is what I got told right as it makes sense...
