Nitrox workshop dings - Divers Alert Network

Rubicon Foundation Archive (http://rubicon-foundation.org)VI. Final Discussion and Workshop RecommendationsA. Marroni: Thank you for mentioning Project Safe Dive. As you know, we've changed thename as well to DSL, Diving Safety Lab. We are doing it with the help and support ofUwatec that's supplying us with 300 computers. We are already doing a sub-project of theresearch that concerns nitrox and are collecting nitrox dives.DANNitrox Workshop Consensus RecommendationsFor entry-level, recreational open-circuit nitrox diving:• No evidence was presented that showed an increased risk of DCS from the use of oxygenenriched air (nitrox) versus compressed air.• A maximum PO2 of 1.6 arm was accepted based on its history of use and scientific studies.• Routine CO2 retention screening is not necessary.• Oxygen analyzers should use a controlled-flow sampling device.• Oxygen analysis of the breathing gas should be performed by the blender and/or dispenserand verified by the end user.• Training agencies recognize the effectiveness of dive computers.• For recreational diving, there is no need to track whole body exposure to oxygen(OTU/UPTD).• Use of the "CNS Oxygen Clock" concept, based on NOAA oxygen exposure limits, shouldbe taught. However, it should be noted that CNS Oxygen toxicity could occur suddenly andunexpectedly.• No evidence was presented, based on history of use, to show an unreasonable risk of fire orignition when using up to 40% nitrox with standard scuba equipment. The level of risk isrelated to specific equipment configurations and the user should rely on the manufacturer'srecommendations.M. Lang: Barring any other comments, I want to thank you again, on behalf of the Divers AlertNetwork Board of Directors, for your participation. This has been a successful use of ourtime and we look forward to the proceedings publication. Thank you for your support.195
