Hi again
Some more questions for Tom Rose.
Being so informative, about your device, I hope you don't mind few more questions, Tom.

The O2 drying flow - you have to find a compromise between drawing adequate gas sample for monitoring CO2 and still not affecting to much the PPO2 in the loop. Is there a potential for the hyperoxia in certain situation like rapid decent? And again my understanding is you are using some kind of orifice/ venturi tube in your aspirator. Is there potential, pardon my language, for sucking in some sorb dust and plugging it? Finally the mysterious(for me) membrane open for water vapors and impenetrable for the CO2 molecules. Can you say something more about it or it is a trade secret?
