It demonstrates how to devise effective treatment solutions when the traditional tools (medications, equipment, and staff) are unavailable or when providing care outside your primary area of expertise. In any crisis, from power failures and computer crashes to floods, tsunamis, and earthquakes, knowing how to deal with the unique challenges encountered saves lives and communities. This reference gives you that knowledge and inspires innovative crisis resolution. FROM REVIEWS OF THE FIRST EDITION: "Dr Iserson has given us a most remarkable book. Many readers may be familiar with David Werner's lay healthworker book, Where There Is No Doctor; this new volume could be titled Where There Is a Doctor–But No Stuff. Drawing from his experience providing care in international, wilderness, and disaster settings, he has compiled an impressive collection of bare-bones equipment and work-around strategies to provide the best possible care in resource-poor settings. While presenting many creative examples, the purpose of the book is not to offer an exhaustive list of solutions to missing resource challenges but to inspire creativity in readers who may find themselves needing to improvise." -- Family Medicine “There is a lot of material here and, if nothing else, it may motivate more people to practice low-tech medicine and be willing to go where health care is dependent more on caring than on cost. I recommend this book to anyone who must practice in austere environments, and it will be in my rucksack when I respond to the next disaster.” – The Journal of Emergency Medicine FEATURES: ·Simple-to-follow directions, diagrams, and illustrations describing practical techniques and improvised equipment necessary to provide quality care during crises ·Contains improvisations in anesthesia and airway management, dentistry, gynecology/obstetrics, infectious disease/laboratory diagnosis, internal medicine, otolaryngology, pediatrics and malnutrition, orthopedics, psychiatry, and surgery ·Covers situational analysis and basic needs in a crisis; specific triage, diagnosis, and stabilization efforts; medical interventions for surgical and non-surgical problems; and debunks some commonly reported improvised techniques ·Features public health measures, basic disaster communication techniques, post-disaster forensics, a model hospital disaster plan, and innovative patient-transport methods ·New to the second edition: More concisely written, more extensively illustrated, and updated improvisations and references LEARN HOW TO: ·Make an endotracheal tube in seconds ·Perform digital-oral and blind-nasotracheal intubations ·Make plaster bandages for splints/casts ·Give open-drop ether, ketamine drips, and halothane ·Use subcutaneous/intraperitoneal rehydration/transfusion ·Make ORS and standard nutrition formulas ·Clean, disinfect, and sterilize equipment for reuse ·Warm blood units in seconds inexpensively ·Take/view stereoscopic x-rays with standard equipment ·Quickly and easily stop postpartum hemorrhage ·Fashion surgical equipment from common items ·Build an evaporative refrigerator ·Make esophageal and precordial stethoscopes ·Quickly improvise a saline lock ·Make ECG electrode/defibrillator pads and ultrasound gel ·Evacuate patients easily from high-rise hospitals

Understanding how humans cope in extreme environments has expanded our knowledge of the physiological and psychological challenges involved and helped us to quit our comfortable paradigms built on “steady states”. Furthermore, measuring our reactions to intermittent stressors and determining the oscillations of our coping mechanisms has led us to unexpected understandings. This methodology has also directly improved our translational or multidisciplinary approach to the subject. Studying healthy individuals in extreme environments could improve our understanding of patients with impaired physiological capacities (who are coping with an environment that becomes extreme to them) and also improve our understanding of physiology and psychology in the elderly.This eBook collects articles that address this translational multidisciplinary approach in an integrative way. As a whole, this Research Topic aims to better understand human/animal physiology and psychology.

In the past few years, there has been an explosion of eye movement research in cognitive science and neuroscience. This has been due to the availability of 'off the shelf' eye trackers, along with software to allow the easy acquisition and analysis of eye movement data. Accompanying this has been a realisation that eye movement data can be informative about many different aspects of perceptual and cognitive processing. Eye movements have been used to examine the visual and cognitive processes underpinning a much broader range of human activities, including, language production, dialogue, human computer interaction, driving behaviour, sporting performance, and emotional states. Finally, in the past thirty years, there have been real advances in our understanding of the neural processes that underpin eye movement behaviour. The Oxford Handbook of Eye Movements provides the first comprehensive review of the entire field of eye movement research. In over fifty chapters, it reviews the developments that have so far taken place, the areas actively being researched, and looks at how the field is likely to devlop in the coming years. The first section considers historical and background material, before moving onto section 2 on the neural basis of eye movements. The third and fourth sections looks at visual cognition and eye movements and eye movement pathology and development. The final sections consider eye movements and reading and language processing and eye movements. Bringing together cutting edge research from and international team of leading psychologists, neuroscientists, and vision researchers, this book is the definitive reference work in this field.

The Handbook of Nutrition, Diet and the Eye is the first book to thoroughly address common features and etiological factors in how dietary and nutritional factors affect the eye. The ocular system is perhaps one of the least studied organs in diet and nutrition, yet the consequences of vision loss can be devastating. One of the biggest contributors to complete vision loss in the western hemisphere is diabetes, precipitated by metabolic syndrome. In some developing countries, micronutrient deficiencies are major contributory factors to impaired vision. However, there are a range of ocular defects that have either their origin in nutritional deficiencies or excess or have been shown to respond favorably to nutritional components. The eye from the cornea to the retina may be affected by nutritional components. Effects may be physiological or molecular. This book represents essential reading for nutritionists, dietitians, optometrists, ophthalmologists, opticians, endocrinologists, and other clinicians and researchers interested in eye health and vision in general. Saves clinicians and researchers time in quickly accessing the very latest details on a broad range of nutrition, ocular health, and disease issues Provides a common language for nutritionists, nutrition researchers, optometrists, and ophthalmologists to discuss how dietary and nutritional factors, and related diseases and syndromes affect the eye Preclinical, clinical, and population studies will help nutritionists, dieticians, and clinicians map out key areas for research and further clinical recommendations
