Book Synopsis Bends Explained by : Jeffrey H. Rudell Md
Download or read book Bends Explained written by Jeffrey H. Rudell Md and published by iUniverse. This book was released on 2009-07 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Details about many of the divers that I evaluated are included with comments on the way their dives got them into trouble and the chamber at City Island, NAHC. I discuss their treatment profiles and the results of their treatment. It presents a larger series of bent divers than any I am aware of. Should you find another comparable series contact me at [email protected]. Ideas about bends have changed from the concept that a bubble formed in the nervous system because of a rapid ascent or the joint by cavitation-negative pressure. Rapid ascent or joint motion caused the culprit to appear and pressure would make the bubble go away. Now we are focused on treating tissue damage with oxygen. But, we are still using pressure and oxygen to increase the partial pressure of oxygen in the affected tissue. The treatment of choice is the 5 hour long U.S. Navy Treatment Table 6 which washes out the nitrogen in the tissue and washes in the oxygen. Careful understanding of how my patients got bent and how they responded should make any diver more cautious regarding repetitive diving and a multi-day series of dives. Pressure at the deepest part of the dive washes in the nitrogen over time. Fatty tissue, that includes the central nervous system and peripheral nerves, absorbs more nitrogen than watery tissues such as muscle. Shaping-up to dive includes weight loss, abstinence during the duration of the series of dives, and improving lung function. Physical conditioning prevents tachycardia, a rapid heart beat, during exertion. A program of regular exercise two or three times a week prevents early fatigue during prolonged exertion, or increases stamina. Exercise such as walking 20 or more minutes a day for several weeks before diving is as important as paying for the trip. Swimming accustoms one to buoyancy, relaxing in the water, and adjusting temperature regulating reflexes such as vaso-constriction in the skin on immersion. Dive accidents sometimes do not have a treatable solution. Most "accidents" resolve after one re-compression breathing oxygen under pressure. Many patients were treated multiple times, and some did not get complete relief of their symptoms and/or neurological findings. Immediate therapy traditionally is in-water re-compression which has its drawbacks. It is difficult to administer and hypothermia, fatigue, and drowning are risks. Surface-On-Deck oxygen breathing from a face-mask or immediate re-compression in a chamber are always effective treatments. Transport to a facility has logistical problems and the destination chamber may not be functional when it is needed. The U.S. Navy Diving Manual Rev.6 Vol. 5 20-4.4.2.1 has procedures for In-Water Re-compression using AIR, 20-4.4.2.2 In-Water Re-compression Using Oxygen. Both sections advise going to 30 fsw and additional instructions for decompressing. If oxygen is used and the decompression has been completed then 3 hours of oxygen breathing is the procedure. One cylinder of oxygen and a face mask are good for one diver for 3 hours. Where are the other cylinders for other divers? The book is about the chamber that I personally operated and staffed. I was almost continually available. The number of bent divers that I treated, not all are included in the book because they were routine, speaks for itself. AAA, Avoid An Accident-Plan Safe Dives.
Download or read book The Bends written by John L. Phillips and published by Yale University Press. This book was released on 1998-01-01 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the invention of compressed air in the 1840s, human divers could enter previously inaccessible deep water environments and engineers could design underwater mines and monumental bridges that had never been possible before. But a painful, sometimes fatal illness--decompression sickness, or the bends--mysteriously afflicted many of those who used compressed air. This book is a wide-ranging history of the wonders compressed air brought about and the suffering its unknown hazards inflicted. John L. Phillips explores the intertwining roles of science, technology, engineering, medicine, and politics in the invention of compressed air, the recognition and identification of decompression sickness, and the hundred-year-long process of learning to understand and treat the bends. The book begins with an overview of the biology and chemistry of respiration and a discussion of the steam engine that could generate compressed air. Drawing on previously unpublished letters, diaries, and notes, Phillips tells the story of early uses of compressed air, first observations of decompression sickness, growing awareness of the bends during construction of the Brooklyn Bridge, and efforts to understand the pathophysiology of the illness. He then considers employee health and safety issues, the science of diving today, and human limits to exploring the ocean deeps. In the history of compressed air and its illnesses, Phillips finds important lessons for dealing with other diseases yet to be confronted in the modern world.
Book Synopsis Between the Devil and the Deep by : Mark Cowan
Download or read book Between the Devil and the Deep written by Mark Cowan and published by Unbound Publishing. This book was released on 2021-07-22 with total page 361 pages. 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.

Book Synopsis How the Color Line Bends by : Nina M. Yancy
Download or read book How the Color Line Bends written by Nina M. Yancy and published by Oxford University Press. This book was released on 2022 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: "How the Color Line Bends explores the connection between prejudice and place in modern America. Existing scholarship suggests that living near Black Americans presents a "threat" to White Americans, which in turn influences White opinions on policies related to race. This book rejects the tendency to position White people as tacit victims and Black people as threatening, instead recasting White Americans as active viewers of their surroundings. This reframing brings a critical focus on power and positionality to scholarship on racial threat, and challenges the neutrality typically assigned to the White perspective. The book first presents ethnographic analysis of Louisiana residents caught in a racialized debate over incorporating a new city in the Baton Rouge area, using interpretive methods to show how race colors White residents' perspective on local geography and politics. Then, the book applies its conceptualization of a White perspective to the quantitative study of prejudice and place, revisiting the classic racialized policy issues of welfare and affirmative action. These analyses emphasize White Americans' diverse beliefs and surroundings but also their common structural position, and how an interest in defending that position shapes the White perspective. This emphasis supports new empirical insights on the behavior of racially tolerant White people, perceptions of the Black middle class, and the consequences of segregation for racial politics. The book also includes discussion of the author's own positionality as a Black woman researcher in conversation with White interview subjects, and the risks of Whiteness studies that leave Black people invisible"--
