Available in PDF, EPUB and Kindle. Book excerpt: Manned space flight alters cardiovascular function. Confinement and weightlessness cause function changes similar to inactivity, designated as cardiovascular de-conditioning. This includes decreased exercise and orthostatic tolerance. The influence of weightlessness as a separate environmental factor cannot yet be determined since manned space flights involve multiple changes in environmental factors that also effect cardiovascular function. Preliminary data and laboratory studies suggest that with a good life support system man can tolerate the weightlessness of space flight for at least one month.

The introductory chapter demonstrates how human neuromuscular system can withstand the stresses of short-term space travel. The succeeding chapters describe human responses under space acceleration stress. These topics are followed by discussions on human stress tolerance capacity; psychological aspects of space flight; instrumentation in biomedical capsules in space flight; and the phenomenon of space weightlessness. The final chapter deals with the impact of the environment on the man and the impact that the man has on the environment, including environmental, metabolic, and waste removal parameters. This book is of value to space scientists and researchers.
Download or read book Spaceflight Associated Neuro Ocular Syndrome written by Andrew G. Lee and published by Academic Press. This book was released on 2022-07-16 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prolonged microgravity exposure during long-duration spaceflight (LDSF) produces unusual physiologic and pathologic neuro-ophthalmic findings in astronauts. These microgravity-associated findings collectively define the Spaceflight Associated Neuro-ocular Syndrome (SANS). In this book, the editors compare and contrast prior published work on SANS by the National Aeronautics and Space Administration’s (NASA) Space Medicine Operations Division with retrospective and prospective studies from other research groups. The book describes the possible mechanisms and potential etiologies for SANS, and provides an update and review on the clinical manifestations of SANS including: unilateral and bilateral optic disc edema, globe flattening, choroidal and retinal folds, hyperopic refractive error shifts, and focal areas of ischemic retina (i.e., cotton wool spots). The ocular imaging findings (e.g., retinal nerve fiber layer, optic disc, and choroidal changes on optical coherence tomography) of SANS is also described, including the intraorbital and intracranial findings on orbital ultrasound and magnetic resonance imaging. The knowledge gaps for in-flight and terrestrial human research including potential countermeasures for future stud is also explored, including reports on the in-flight and terrestrial human and animal research being investigated by NASA and its partners to study SANS both prospectively and longitudinally and in preparation for future long duration manned missions to space including the moon, the asteroid belt, or Mars. We think this is a unique topic and hope that NASA and its research partners continue to study SANS in preparation for future longer duration manned space missions. Written in an easy-to-read manner, the book adopts a translational approach and explores the science and the clinical manifestations of Space flight associated neuro-ocular syndrome. It is also multi-disciplinary and suitable for both clinicians and researchers in ophthalmology, neurology, and aerospace medicine interested in SANS SANS is a unique space flight disorder that has no terrestrial equivalent. The book involves contributions from international experts across multiple disciplines to tackle the problem of SANS Summarizes and reviews the current findings of SANS, including possible mechanisms and potential etiologies, clinical manifestations, current reports on the in-flight and terrestrial human and animal research, and ocular imaging findings

This book was released on 2012-01-30 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.

Available in PDF, EPUB and Kindle. Book excerpt: Safe Passage: Astronaut Care for Exploration Missions sets forth a vision for space medicine as it applies to deep space voyage. As space missions increase in duration from months to years and extend well beyond Earth's orbit, so will the attendant risks of working in these extreme and isolated environmental conditions. Hazards to astronaut health range from greater radiation exposure and loss of bone and muscle density to intensified psychological stress from living with others in a confined space. Going beyond the body of biomedical research, the report examines existing space medicine clinical and behavioral research and health care data and the policies attendant to them. It describes why not enough is known today about the dangers of prolonged travel to enable humans to venture into deep space in a safe and sane manner. The report makes a number of recommendations concerning NASA's structure for clinical and behavioral research, on the need for a comprehensive astronaut health care system and on an approach to communicating health and safety risks to astronauts, their families, and the public.

Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
Download or read book The Neurolab Spacelab Mission written by Jay C. Buckey and published by Lyndon B. Johnson Space Center. This book was released on 2003 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offers solutions and best practices to respond to recurrent problems and contemporary challenges in the field Since the publication of the first edition of Environmental Impact Assessment in 2003, both the practice and theory of impact assessment have changed substantially. Not only has the field been subject to a great deal of new regulations and guidelines, it has also evolved tremendously, with a greater emphasis on strategic environmental, sustainability, and human health impact assessments. Moreover, there is a greater call for impact assessments from a global perspective. This Second Edition, now titled Impact Assessment to reflect its broader scope and the breadth of these many changes, offers students and practitioners a current guide to today's impact assessment practice. Impact Assessment begins with an introduction and then a chapter reviewing conventional approaches to the field. Next, the book is organized around recurrent problems and contemporary challenges in impact assessment process design and management, enabling readers to quickly find the material they need to solve tough problems, including: How to make impact assessments more influential, rigorous, rational, substantive, practical, democratic, collaborative, ethical, and adaptive How each problem and challenge-reducing process would operate at the regulatory and applied levels How each problem can be approached for different impact assessment types-sustainability assessment, strategic environmental assessment, project-level EIA, social impact assessment, ecological impact assessment, and health impact assessment How to link and combine impact assessment processes to operate in situations with multiple overlapping problems, challenges, and impact assessment types How to connect and combine impact assessment processes Each chapter first addresses the topic with current theory and then demonstrates how that theory is applied, presenting requirements, guidelines, and best practices. Summaries at the end of each chapter provide a handy tool for structuring the design and evaluation of impact assessment processes and documents. Readers will find analyses and new case studies that address such issues as multi-jurisdictional impact assessment, climate change, cumulative effects assessment, follow-up, capacity building, interpreting significance, and the siting of major industrial and waste facilities. Reflecting current theory and standards of practice, Impact Assessment is appropriate for both students and practitioners in the field, enabling them to confidently respond to a myriad of new challenges in the field.
