The results of a six-month intensive study of the problems peculiar to civil aviation in the 40,000 to 50,000 foot flight range are reported, leading to a comprehensive set of recommendations for equipment design, testing practices, personnel selection and indoctrination, and overall research and development policy. In addition to reviewing much of the pertinent literature of the past twenty-five years, the report analyzes in detail the results of recently completed experiments dealing specifically with rapid decompression under conditions representative of the civil aviation potential emergency. From this analysis a system is derived for predicting the time of onset, depth, and duration of functional impairment in decompressions while breathing air or enriched mixtures. In addition, a criterion is proposed for pre-decompression breathing mixtures which will preclude post-decompression impairment. Included are numerous comparative tables and figures describing typical oxygen equipment, a bibliography of over 200 reports, abstracts of some key articles, and several reference charts and nomographs. Certain unpublished data on cerebral oxygenation are included in complete form. Author
