Hello Simon, I'm trying all my best and worst to find any recordings, texts or just anything about your two lectures at Eurotek 2016 (I couldn't attend it): 1:- “Removing carbon dioxide from your loop: why and how?" Basic CO2 physiology & the importance of maintaining normal CO2 levels during diving. 2:- “Intelligent Scrubbing: Improving safe use of CO2 absorbents”. The importance of efficient removal of CO2 from the exhaled gas during CCR diving. I'd be very thankful if you let me know where I may find those. Thank your very much! Best regards, Gregory.
