This book was released on 2016-10-05 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biophysics of diving and decompression in the human body are complex. The average individual experiences atmospheric pressure swings of 3% at sea level and over 20% at altitudes greater than a mile. Divers and their equipment can experience compressions and decompressions in orders of greater magnitude than pressures outside water, all within considerably shorter time spans. The understanding of the mechanics behind diving is based on absolute pressure and pressure changes. While these mechanics are readily quantified in physics, chemistry, and engineering applications, the physiological and medical aspects of pressure changes in living systems need to be understood clearly to assess the safety of routine divers. This monograph is a compilation of a body of knowledge on biophysics, gas transport, bubble studies and physiological models used for diving and hyperbaric applications. Information in the monograph is divided into three parts that cover biophysics and models, data correlation and validation approaches and practical applications, respectively. The book is a useful resource for researchers and maritime professionals who wish to understand the biophysics behind underwater diving and decompression for the purpose of maritime operations as well as diving simulation applications.

Available in PDF, EPUB and Kindle. Book excerpt: 'One of the best accounts ever written of deep-water diving and its staggering, haunting dangers' Robert Kurson, New York Times bestselling author of Shadow Divers Deep underwater lurks a mysterious man-made illness. It has gone by many names over the years – Satan’s disease, diver’s palsy, the chokes – but today, medics call it decompression sickness. You know it as the bends. That’s the devil British diver Martin Robson faces each time he plunges beneath the surface. In the winter of 2012, Robson was part of an expedition to Blue Lake, southern Russia, which sought to find a submerged cave system never seen by the human eye. On the final day of the expedition, as Robson returned from diving deeper into the lake than anyone had before, disaster struck: just seventy-five feet down, he was ambushed by the bends. Robson knew that if he continued up to the surface he would probably die before help arrived. Instead, he sank back into the water, gambling on an underwater practice most doctors believe is a suicidal act. Soon the only hope he had of saving his life would rest in the hands of a dramatic mercy mission organised at the highest levels of the Russian government. Between the Devil and the Deep is the first book to tell the terrifying true story of what it feels like to get the bends, taking you inside the body and mind of a man who suffered the unthinkable. Writer Mark Cowan also explores the grimly fascinating history of decompression sickness, the science behind what causes the disease, and the stories of the forgotten divers who pushed the limits of physical endurance to help find a solution.

Download or read book Scuba Physiological written by Simon Pridmore and published by Simon Pridmore. This book was released on 2021-10-26 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: If you are a diver, what you learned about topics such as decompression sickness and narcosis in your scuba diving classes is unlikely to have been as complete as you thought. Most of it will have been over-simplified and some of it will just have been plain wrong, as diver training agency texts have not kept pace with the science. Scuba Physiological gives you a chance to catch up. A recent book called The Science of Diving was a collation of work done by scientists in the field of decompression research as part of a three-year project called PHYPODE (Physiology of Decompression). The book did not reach the diving public; mainly because it was written by scientists for other scientists and they speak a different language than most of us. Simon Pridmore is not an expert on diving medicine but he knows something good when he sees it. When Simon read The Science of Diving (with help from Google), he thought it was worthwhile working on it to try to make it more accessible. The original authors agreed that this was a good idea and Scuba Physiological is the result. There have been great advances to make diving safer, but, despite nearly 170 years of research, the fundamental nature of decompression sickness and decompression stress remains unknown and there are still glaring gaps in our knowledge. Scuba Physiological provides a good summary of what we know, as well as a glimpse of where the science is taking us and some invaluable tips to make you a safer diver now. Among many other things, you will learn: 1. Pre-dive hydration, exposure to heat, whole body vibration and oxygen breathing may reduce the risk of DCS. 2. Post-dive, our bodies have most bubbles running around them 30 to 40 minutes AFTER we have surfaced. Post-dive hydration and certain other post-dive behaviours are therefore also essential. 3. The effects of nitrogen narcosis continue for a period of time AFTER a dive. 4. All dive computers have a known DCS risk rate. 5. Exercise during the period up to 120 minutes after surfacing may increase your risk of DCS. 6. Never use a weightlifter's breath-hold and release technique when pulling yourself into the boat post-dive. 7. A little dark chocolate before a dive may be a good thing for you. What the experts say: “With this latest volume, Simon Pridmore makes a significant contribution to the body of practical knowledge in the science of scuba diving. If you are looking for a thorough understanding of the science of diving and how it might be impacting your safety and enjoyment of diving, this book is a must read.” Dan Orr, President, Academy of Underwater Arts & Sciences and President Emeritus, Divers Alert Network Foundation "This book makes it easy to understand the latest discoveries in diving research and our current understanding of what happens to our bodies when we dive." JP Imbert: Decompression designer and technical diving pioneer "There are some lovely thought-provoking ideas and questioning of current dogma. This book is well worth the read. " Dr Ian Sibley-Calder, HSE Approved Medical Examiner of Divers, Occupational Health Physician "This book is an excellent discussion of the issues. It is an enjoyable, simplified read of a complex subject and easy for a non-scientist to comprehend. I consider this an essential text for every diver's shelf."

Available in PDF, EPUB and Kindle. Book excerpt: You will find in this book some valuable and reliable lessons about safe diving The editors of and authors of this book are a cadre of scientists and physicians with broad experience and knowledge of diving physiology and decompression theory. As is often the case, it requires a group effort to succeed in advancing practical knowledge. The colloquialism "the whole is greater than the sum of its parts" is often true and the PHYPODE Reasearch Group epitomizes this concept. By logically grouping the various elements of diving science and medicine with provocative "food for thought" sections, the text offers valuable lessons to those interested in the current state of diving. Despite nearly 170 years of reasearch, the fundamenal nature of decompression stress remains elusive. As is well outlined in this book, great advances have been made to the practical elements allowing for safe diving. Nonetheless, there are glaring voids of knowledge related to the nature of bubble nucleation, its consequences and methods to ameliorate risk. The synergy exhibited in this text not only provides a foundation for what is known, it offers a glimpse of where research is taking us. - Professor Stephen R. Thom, Dept. of Emergency Medicine, University of Maryland School of Medicine This is a book for all diving fans who want to discover their passion through a scientific approach. EXCERPT Decompression illnesses (DCI), or as they are called more scientifically: dysbaric disorders, represent a complex spectrum of pathophysiological conditions with a wide variety of signs and symptoms related to dissolved gas and its subsequent phase change.1, 2 Any significant organic or functional dysfunction in individuals who have recently been exposed to a reduction in environmental pressure (i.e., decompression) must be considered as possibly being caused by DCI until proven otherwise. However, apart from the more obvious acute manifestations of a single, sudden decompression, individuals who have experienced repetitive exposures (e.g. commercial or professional divers and active recreational divers) may also develop sub-acute or chronic manifestations, even if subtle and almost symptomless. ABOUT THE AUTHORS Dr. Costantino Balestra started to study neurophysiology of fatigue then started studies on environmental physiology issues. He teaches physiology, biostatistics, research methodology, as well as other subjects.

Download or read book Diving Physics with Bubble Mechanics and Decompression Theory in Depth written by B. R Wienke and published by . This book was released on 2008 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on physics and associated mathematical relationships. Basic principles are first presented, and then practical applications and results are detailed. The intent here is to present a working view of physical phase mechanics, then followed by application to decompression theory in diving. It is directed toward the diver and reader with a basic understanding of decompression. Basically the mechanics of tissue gas exchange, bubbles and nucleation, supersaturation, perfusion and diffusion, and related mechanisms are discussed. The targeted audience is especially the doctor or physiologist, physicist, chemist, mathematician, engineer or biologist by training and also the commercial diver, technical diver, instructor, hyperbaric technician, underwater researcher, looking for greater detail.
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.

" Dr Ian Sibley-Calder, HSE Approved Medical Examiner of Divers, Occupational Health Physician "If you ask a lay person what causes DCS they will likely tell you, "I don't know, I think it has something to do with bubbles". If you ask a dive instructor they might discuss things like shaking a soda bottle. And, if you ask a physician, you may get an account referring to things like leukocyte adhesion, the coagulation of components inside a vein and the endothelium lining. Finally, you find one of the top people in the world who do hyperbaric research on divers, ask them the same question and they will say, "I don't know, I think it has something to do with bubbles. The bottom line is that we don't necessarily know what causes DCS. This book is an excellent discussion of what the third person you asked in the above scenario might say.
