DIVING EVALUATION

THIS STUDY WOULD DEFINE THE STATE-OF-THE-ART FOR THE USE OF HYDROGENOXYGEN MIXTURES FOR DIVING OPERATIONS BY COMPILING INFORMATION RELATIVE TO PAST AND CURRENT RESEARCH EFFORTS IN THE U. S. AND FOREIGN COUNTRIES. THIS INFORMATION WOULD BE UTILIZED TO DEVELOP A RATIONALE FOR THE USE OF THIS MIXTURE FOR APPROXIMATE CONDITIONS AND DEFINE AREAS IN WHICH HYDROGEN-OXYGEN MIXTURES WOULD OFFER PHYSIOLOGICAL ADVANTAGES NOT POSSIBLE WITH CURRENTLY USED DIVING MIXTURES. FURTHER RESEARCH REQUIREMENTS PRIOR TO OPERATIONAL USE OF THIS MIXTURE WOULD BE INDICATED FROM THIS STUDY AND RECOMMENDATIONS FOR CURRENT AND FUTURE RESEARCH AND DEVELOPMENT NEEDS WOULD BE INCLUDED IN THE FINAL REPORT.
