SUBMARINE ACCIDENTS AND ESCAPE AND RESCUE Effects of inert gas narcosis, hypo- and hyperthermia, hypoxia, hyperoxia, hypercarbia, and atmospheric contaminants on crew physiology and performance. Development of a physiologically-based algorithm for guiding escape vs. rescue decisions based on a mathematical model of the interaction of the disabled submarine environment and the crew condition. Factors include internal and external submarine environment (temperature, pressure, atmosphere composition, flooding, location of supplies and equipment, etc.) and their effects on crew physiology and performance. Estimates of crew survival, mortality, and morbidity for various disabled submarine scenarios. Optimization of rescue and escape supplies and equipment. Medical requirements for treatment of survivors and supply logistics for various disabled submarine scenarios. Development and evaluation of rescue and survival equipment and procedures. Decompression sickness risk assessment and amelioration. SCREENING, QUALIFICATION, AND HEALTH EFFECTS OF SUBMARINE DUTY Psychiatric, performance and motivational screening, selection and intervention procedures to reduce attrition rates for submarine personnel during both training for and actual submarine service to include both nuclear reactor and submarine schools. Evaluation of current medical qualification standards, prevention of stress-related disorders, and determination of disqualification criteria for various medical conditions as they relate to submarine duty. Epidemiological studies of submariners and health effects of long-term exposure to the submarine environment including studies of mortality, morbidity, precipitating factors, and the long-term course of diseases and injuries.
