Available in PDF, EPUB and Kindle. Book excerpt: Eighty dives were executed to explore the use of helium-oxygen mixtures in mixed-gas diving with regard to oxygen toxicity. The double-blind technique was used to test 40% and 50% oxygen in helium mixtures at eight depth-time intervals. The Experimental Diving Unit method of underwater electrocardiography was used for the first time in an attempt to predict the onset of oxygen toxicity prior to the convulsion manifestations. No evidence of oxygen toxicity was exhibited even though the presently accepted depth-time oxygen exposure limits were greatly exceeded. (Author)

Available in PDF, EPUB and Kindle. Book excerpt: A decompression procedure for use of helium-oxygen mixtures in mixed gas SCUBA to permit repetitive dives to a depth of 200 feet has been developed employing modified Haldane principles. The repetitive diving procedure provides a system by which a diver can determine the necessary increase in decompression time on successive dives, based on the amount of excess inert gas tension in body tissues after completion of previous dives. The amount of decompression required is decreased by the time interval at the surface between dives. The information required for use of this system is obtained from four tables: (1) Decompression table (2) No decompression dive table (3) Surface interval credit table and (4) Repetitive dive time table. A method for use of oxygen decompression at 30 and 20 foot water stops is also provided. The validity of this procedure is based on tests of 486 dives in which 28 three-dive series and 68 oxygen decompression dives were made. The procedure as reported is considered satisfactory and is recommended for further testing under operational conditions in the field before service-wide use. (Author).

Download or read book Evaluation of Breathing Mixtures to be Used During Decompression for Mixed Gas Surface Supplied Dives written by Peter O. Edel and published by . This book was released on 1982 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: One important tool in table computation is shifting inert gasses during decompression. Proper application of this technique may result in the saving of large percentages of decompression time. In the case of a dive involving the use of helium-oxygen on the bottom, the standard procedure involves switching the breathing mixture to nitrogen-oxygen during decompression. In this case, added advantages of improved thermal comfort to the diver and generally better communications from the diver to surface are provided by this switching technique. This technique has been extensively used with very good results in foreign naval and domestic, as well as foreign, commercial diving operations over the past decade and proper application of this technique would provide significant reductions in decompression requirements for and future recomputation of the U.S. Navy Surface Supplied Mixed Gas Tables. It is the purpose of this study to make a mathematical evaluation of various possible nitrogen-oxygen mixtures and optimum depth at which they might be applied during the decompression following a helium-oxygen exposure within the anticipated depth-time requirements of the U.S. Navy.
