Available in PDF, EPUB and Kindle. Book excerpt: The Laboratory of Hyperbaric Physiology of the Medical Clinic of the University of Zurich came into existence in 1960 thanks to private initiative and a readiness to undertake risks; the success ful start was made possible with help from the French Navy and the United States Navy. A prerequisite for the development of the laboratory was also the benevolence of the authorities of the University of Zurich toward a research project from which scarcely any practical use could be expected for the land-locked country of Switzerland. The development of the laboratory and the systematic research were supported generously from 1964 by Shell Intemationale Petroleum Maatschappij of The Hague. The basic theme of the research was always the well-being and functional ability of the human being in an atmosphere of abnor mal pressure and or abnormal composition. Many connections became obvious with respiratory physiolo gy, circulatory physiology, and physiology at great heigts, and close contact with other special laboratories of the Medical Clin ic proved very valuable. With a relatively small number of steady collaborators it was possible to master an extensive experimental program. Special thanks are due to Mr. Benno Schenk, who as technical head was responsible for the exact performance of all the hyperbaric experiments.

This book was released on 1966 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The additional decrease in ambient pressure which occurs when a compressed air diver flies in an aircraft within a short time after diving may be sufficient to precipitate decompression sickness, even though the dive itself was in accordance with the U.S. Navy decompression tables. The current practice by both military and civilian divers of using air transportation after compressed air diving suggests the need for specific instructions regarding the decompression required before flying after diving. In order to quantitate the importance of this problem, an experiment was designed in which large dogs were exposed to compressed air for 7 hours at their 'no-bends' pressure threshold as determined after the method of Reeves and Beckman. After pressurization, the animals were decompressed within 2-3 minutes to sea level. A sea level decompression interval of 1, 3, 6, or 12 hours was given prior to further decompression to a simulated altitude of 10,000 feet. The incidence of decompression sickness at altitude was 92.9% for the 1 hour surface decompression interval, 30% for the 3 hour interval, 27.8% for the 6 hour interval and 0% for the 12 hour interval. From these large animal studies it may be postulated that a surface decompression interval of at least 12 hours should be allowed before flying after compressed air diving of a depth and duration to require the use of diving tables.

Download or read book Evidence based Approach to the Analysis of Serious Decompression Sickness with Application to EVA Astronauts written by Johnny Conkin and published by . This book was released on 2001 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is important to understand the risk of serious hypobaric decompression sickness (DCS) to develop procedures and treatment responses to mitigate the risk. Since it is not ethical to conduct prospective tests about serious DCS with humans, the necessary information was gathered from 73 published reports. We hypothesize that a 4-hr 100% oxygen (O2) prebreathe results in a very low risk of serious DCS, and test this through analysis. We evaluated 258 tests containing information from 79,366 exposures in altitude chambers. Serious DCS was documented in 918 men during the tests. A risk function analysis with maximum likelihood optimization was performed to identify significant explanatory variables, and to create a predictive model for the probability of serious DCS [P(serious DCS)]. Useful variables were Tissue Ratio, the planned time spent at altitude (Talt), and whether or not repetitive exercise was performed at altitude. Tissue Ratio is P1N2/P2, where P1N2 is calculated (N2) pressure in a compartment with a 180-min half-time for N2 pressure just before ascent, and P2 is ambient pressure after ascent. A prebreathe and decompression profile Shuttle astronauts use for extravehicular activity (EVA) includes a 4-hr prebreathe with 100% O2, an ascent to P2=4.3 lb per sq. in. absolute, and a Talt=6 hr. The P(serious DCS) is: 0.0014 (0.00096-0.00196, 95% confidence interval) with exercise and 0.00025 (0.00016-0.00035) without exercise. Given 100 Shuttle EVAs to date and no report of serious DCS, the true risk is less than 0.03 with 95% confidence (Binomial Theorem). It is problematic to estimate the risk of serious DCS since it appears infrequently, even if the estimate is based on thousands of altitude chamber exposures. The true risk to astronauts may lie between the extremes of the confidence intervals since the contribution of other factors, particularly exercise, to the risk of serious DCS during EVA is unknown. A simple model that only accounts for four important variables in retrospective data is still helpful to increase our understanding about the risk of serious DCS.

Download or read book The Physician s Guide to Diving Medicine written by C.B. Carlston and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to be a physician's guide for those interested in diving and hyperbaric environments. It is not a detailed document for the erudite researcher; rather, it is a source of information for the scuba-diving physician who is searching for answers put to him by his fellow nonmedical divers. Following the publication of The Underwater Handbook: A Guide to Physiology and Performance for the Engineer there were frequent requests for a companion volume for the physician. This book is designed to fill the void. Production of the book has been supported by the Office of Naval Research and by the Bureau of Medicine and Surgery, Research and Development Command, under Navy Contract No. NOOOOI4-78-C-0604. Our heartfelt thanks go to the many authors without whose contributions the book could not have been produced. These articles are signed by the responsible authors, and the names a~e also listed alphabetically in these preliminary pages. Every chapter was officially reviewed by at least one expert in the field covered and these reviewers are also listed on these pages. Our thanks go to them for their valuable assistance. We are grateful to Marthe Beckett Kent for editing Chapter III. Our thanks also go to Mrs. Carolyn Paddon for typing and retyping the manuscripts, and to Mrs. Catherine Coppola, who so expertly handled the many fiscal affairs.

Download or read book Basic Decompression written by Bruce R. Wienke and published by . This book was released on 2008 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: "3rd Edition of BASIC DECOMPRESSION THEORY AND APPLICATION takes all rudiments of decompression theory and phase mechanics to considerable depth, while focusing on diving applications in a historical perspective. Topics span many disciplines, and the targeted audience is the commercial diver, hyperbaric scientist, doctor, physical scientist, technical diver, and dive instructor. The intent of the 3rd Edition is to present a working view of decompression in diving, mostly focusing on theory with application, including equations. The discussion is neither a medical nor physiological synthesis. Such aspects are simplified, and for some certainly oversimplified. Nonetheless, it is directed toward the diver and reader with some rudimentary understanding of decompression. Background in the physical or life sciences is helpful but certainly not necessary. Discussed are the mechanics of tissue gas exchange, bubbles and nucleation, supersaturation, perfusion and diffusion. Also included are chapters on "Mixed Gases and Decompression" - "Decompression Tables, Meters and Models" - "Decompression Risks and Statistics." References and numerical examples (with solutions) are included for more detail and extended diver analysis."--Publisher's website.
