Diving Report. Incidents and Accidents in Breath-Hold Diving. Both fatal and nonfatal cases are collected to identify risks and aid in public education. Data from case reports is included in the DAN Annual Diving Report. Project Dive Exploration (PDE). Dive profiles, diver characteristics and diver behaviour are uploaded by volunteers using the dive computer's dive log software and recorded for statistically accurate analysis. This is a prospective observational study of the demographics, medical history, depth-time exposure and medical outcome of a sample of the recreational diving population, with the intention of finding the incidence of decompression sickness in population subgroups and the relationship of DCS probability to depth-time profile and dive and diver characteristics. The data also provides an injury-free control population for comparison with DAN's injury and fatality data to identify possible risk factors associated with injury and death. The results of this study are likely to be useful in the development of future decompression models. Divers using one of many compatible dive computers may contribute their electronic dive log data to PDE. DAN Membership Health Survey (DMHS). To establish the prevalence of cardiovascular risk factors, diabetes and asthma, access to primary health care and the diving practices of DAN Members to help the diving community decide on preventive measures for injuries and fatalities. Database of Dive Exposure and Dive Outcomes. Data from the US Navy, Duke University, PDE, DAN Europe's Dive Safety Lab and the Institute of Nautical Archaeology are converted to a format which can be used as a reference database for calibration and evaluation of decompression algorithms. Diver Physical Fitness Study. Physical fitness of divers and the physical fitness required for typical diving activities will be assessed. Fatality Database. DAN collects data on diving fatalities of recreational divers in the US, Canada and diving destinations frequented by US and Canadian divers, compiles case reports, and includes the data in the DAN Annual Diving Report. Publications DAN publishes research results on a wide range of matters relating to diving safety and medicine and diving accident analysis, including annual reports on decompression illness and diving fatalities. Most are freely available on the internet, many of these at the Rubicon Research Repository. Conferences Rebreather Forum 3 In May 2012, DAN along with the American Academy of Underwater Sciences and the Professional Association of Diving Instructors hosted the Rebreather Forum 3 (RF3) which was organised by Rosemary E Lunn.
