Tomorrow I am flying to Italy to join the other European UTD Instructors and divers who are taking part in the Ratio Deco Decompression Study / Conference this weekend October 11/12, 2014. Over the last several years Italian diving doctors and researchers have being doing a research study on UTDs Ratio Deco decompression strategy. They have found it to be significantly better than other methods or models for decompression. In fact, they have found that the way we structure our ascent profile, use O2, and shape the deco into S-curves significantly improves your decompression outcome and ultimately reduces your risk of DCS. This is something we have known and practiced for years at UTD, however this is the first medical / scientific study which proves it.” The results show Ratio Deco is a superior method / model for decompression, whether it be mandatory stage decompression or simply a safe recreational ascent profile. I will be giving a talk at the conference, along with the doctors who did the research, and hopefully together we will be able to help the divers and instructors who are attending this conference understand how Ratio Deco works and why Ratio Deco works. We will also address how all divers can implement Ratio Deco into their diving, making each ascent safer. I will be putting together a post conference article revealing the scientific findings and presentations. My goal is to influence more everyday divers and encourage other training agencies to adopt some of our methodology, even if it is simple steps like promoting the idea of conducting your first safety deco stop at 50% of your depth and then 1 min per 10/3m ascent from there. The archaic idea of leaving your bottom depth, lets say 100/30m, and ascending to 15/5m to conduct your first “safety stop is outdated and dangerous. As this study shows, to significantly reduce your risk of DCS and improve the way you feel after a recreational dive, you should ascend to 50% of your depth, so so from 100’/30m to 50/15m and then ascend one minute per 10/3m from there. Arrive at the surface 5 min later. Compared to a 15/3m stop for three minutes, because of the shape (linear) and place you started your first stop, 50/15m, bubble growth and number of bubbles are significantly reduced, therefore reducing your risk of DCS.
