Download or read book Computation of Continuous Decompression Schedules for Deep Sea Dives written by James S. Robertson and published by . This book was released on 1968 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A digital computer program for calculating either continuous ascent or stop type decompression schedules is described, and examples of applications are given. The formulas used for continuous ascent were obtained analytically as solutions of differential equations relating the inert gas tension in the current critical tissue to the safe depth and with the actual depth kept equal to the safe depth at all times after an initial fast rise from the bottom to the safe depth. Thus the rate of decompression of the critical tissue controls the rate of ascent. Gas tensions in nine tissues having the same range of gas exchange half-times as have been used in EDU reports are calculated on a continuous basis, with the one having the deepest safe depth being the current critical tissue. The stop type ascent portion of the program may be used to generate a staged ascent using the same parameters for comparison with the continuous ascent schedule. The starting conditions for ascent may either be computed by the program from the dive history or be communicated to it as a subroutine in connection with another program. The program may be used either to prescribe ascent schedules or to analyze dives for which the history is known.

Available in PDF, EPUB and Kindle. Book excerpt: Underwater Physiology is a collection of papers that deals with the physiologically limiting effects of undersea, high pressure exposure ranging from fundamental biological reactions, through integration of physiological stresses, and to limits actually experienced in deep diving. Papers discuss oxygen, the mechanisms of toxicity, and the effects of oxygen on cells and systems such as its pathological and physiological influences in the neurosensory ocular tissue. Other papers discuss the physical effects of pressure and gases on cellular function, protein structure, and the possibility of alleviating symptoms through the administration of drugs. Tests in mice show that various gases exhibit qualitative and semi-quantitative differences in the characteristics of sickness, reactions to hypoxia, and the time before the onset of symptoms. A computer, programmed for nonlinear gas transfer and other variables, running in real time can compute directly from the breathing mixture and provide a real time solution to decompression sickness under various conditions. A combined therapeutic approach, recompression and dextran (an effective lipemic clearing agent) should be capable of treating decompression sickness in humans. Other papers investigate the influence of inert gases and pressure on the central nervous system, as well as, situations in undersea and manned chamber operations. This collection can prove valuable for physiologists, biochemists, cellular biologists, and researchers involved in deep sea diving.

Download or read book Repetitive Diving Decompression Tables written by and published by . This book was released on 1957 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: A decompression procedure for repetitive diving to depths of 190 feet was devised employing modified Haldane principles which have been reported previously. The repetitive diving tables provide a system by which a diver can determine the necessary increase in decompression time on the second and successive dives, based on the amount of excess inert gas tension in his body after completion of the previous dive. The amount by which the decompression time must be increased varies inversely with the time (on surface) interval between dives. The information for using this system is obtained from four tables i.e. Decompression Table, No Decompression Table, Surface Interval Table and the Repetitive Dive Table. The validity of this procedure was tested by performing 62 repetitive dives with random combinations of depth, time and surface interval.

This book was released on 2012-12-06 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the third annotated bibliography on this subject area to be compiled by these authors. The first, published by Gordon and Breach, Science Publishers, in 1971, was entitled AN ANNOTATED BIBLIOGRAPHY ON DIVING AND SUBMARINE MEDICINE. It covered material published during the 1960's. The second volume, entitled UNDERWATER MEDICINE AND RELATED SCIENCES: A GUIDE TO THE LITERATURE, published in 1973 by Plenum Press, covered primarily material published during 1970 and 1971, with some material from 1968 and 1969. The present volume covers material published during 1972 and 1973, but here again some earlier material has been included. The purpose of these annotated bibliographies is to make available a large proportion of the published material, in abstract form, indexed in such a manner as to make it possible to compile a reasonably complete annotated bibliography on any specific subject area in the field. It is possible thus to learn where the work is being done, by whom, and how extensively. Also, it becomes obvious what areas of research are lacking or inadequate. These specific searches can also form a background of reference material on which to base further research, or from which to write monographs or state-of-the-art surveys. Papers, articles and reports listed here are in most cases readily available.
