Abstract : The status of several closed circuit oxygen scuba is reviewed and recommendations for future developments are made. The German Drager and the USN Mark 3 are discussed in some detail and the USN Mark 4 is briefly described. Further improvements of the Mark 3 are enumerated and continued development is recommended, concurrently with development of the wholly new Mark 4 unit. A brief review of early closed circuit oxygen scuba is included along with an anotated bibliography of previous reports pertinent to this type breathing apparatus. (Author)
