PD87 Divers Alert Network:  2008 Technical Diving Conference. The two-day conference, planned for Jan. 18-19, 2008, in Durham, N.C., will feature four half-day workshops. Discussions will include the operational and medical aspects of technical diving. The forum will also address ways to improve effectiveness and safety.Workshops OverviewPHYSIOLOGY WORKSHOP PLANRespirationNormal respiration and gas exchange at sea level with emphasis on oxygen uptake, CO2 elimination, and ventilatory control. Dependency of CO2 elimination on ventilation. CO2 retention and individual susceptibility. Effects of tidal volume and dead space on alveolar ventilation. Hypo- and hyperventilation. Ventilatory capacity, physical fitness, and respiratory muscle fatigue. Effects of immersion and gas density. Airway collapse and effort independent expiratory flow. Equipment dead space, static lung load, breathing resistance, and work of breathing. Effect of HPNS on respiration. Case reports.CNS Oxygen ToxicityRelevant mechanisms of CNS t
