How could that work? How would you stop the gas in the inhale CL from flowing to the exhale CL? Pressure difference between those CLs would make the gas flow to the exhale lung. Or is there something that I donīt get?

Good question, maybe I wasn't clear or I'm being mush brained, but wouldn't the check/one way/flapper valves take care of that as it does in any dual CL design?
