Title: Validation of Dive Computers
Author: Blogg, SL; Lang, MA; Møllerløkken, A
Abstract: This paper reviews a workshop on the validation of dive computers that was convened by the Baromedical and Environmental Physiology Group of the Norwegian University of Science and Technology on 24 August 2011 in Gdansk, Poland as part of the European Underwater and Baromedical Society annual scientific meeting. The use of dive computers by working (commercial inshore) divers in Norway to determine decompression status is not currently authorized by the legislative body, the Norwegian Labour Inspection Authority. The objectives of the workshop were to devise recommendations for the process of dive computer validation. Dive table and dive computer validation procedures were considered along with their applicability for commercial diving operations. Current European Union validation standards were reviewed, and the lengthy process of validation of the U.S. Navy dive computer explained involving man-dive testing of algorithms using decompression sickness (DCS) as an endpoint. Results from examinations of dive computer algorithms using a test chamber documented a relative conservatism among those dive computers tested. The use of venous gas emboli as an alternative to DCS as measurable endpoint for validation of dive computers was considered. Data were presented on recreational dive computer use and a dive computer management system for scientific divers was outlined. Discussion of presented data resulted in a set of consensus findings and recommendations that were presented to the Norwegian authorities.
