Book excerpt: Current battlefield doctrine indicates that Army aviators must be prepared to engage in sustained operations against enemy forces. Fighting around the clock creates a tactical advantage because of the continuous strain that is placed upon enemy forces. However, this strategy can backfire if there are insufficient U.S. personnel to adequately staff the day and night shifts with well-rested crews. Fatigue produces slow and inaccurate performance, errors of omission, and deteriorations in mood and motivation. In some situations where adequate sleep is not possible, the administration of stimulants is the only effective countermeasure for sleep loss. This study was conducted to determine the efficacy of prophylactic Dexedrine administration for maintenance flight performance in sleep deprived helicopter pilots. Ten UH-60 pilots were exposed to two 40-hour periods of continuous wakefulness in 1 week of testing. During both periods, subjects completed flight in a specially-instrumented UH-60 helicopter, as well as electroencephalographic, cognitive, and mood tests. During one of the deprivation periods, the subjects were administered a 10-mg dose of Dexedrine

Book Synopsis The Efficacy of Dexedrine for the Sustainment of Helicopter Pilot Performance During 64 Hours of Continuous Wakefulness by : John A. Caldwell
Download or read book The Efficacy of Dexedrine for the Sustainment of Helicopter Pilot Performance During 64 Hours of Continuous Wakefulness written by John A. Caldwell and published by . This book was released on 1998-10-01 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this investigation was to establish the efficacy of Dexedrine for sustaining aviator performance despite 64-hours of extended wakefulness. Although earlier flight studies yielded favorable results with no significant side effects, they were restricted to sleep-deprivation periods of only 40 hours. Due to requirements for longer periods of sustained wakefulness, it was necessary to study the efficacy of Dexedrine for maintaining aviator performance during 3 days and 2 nights without sleep. To accomplish this, computerized evaluations of aviator flight skills were conducted at regular intervals as subjects completed standardized flights in a UH-60 helicopter simulator, both: under Dexedrine and placebo. Laboratory-based assessments of cognitive, psychological, and central nervous system status were completed as well. Dexedrine (10 mg.) was given prophylactically (prior to signs of fatigue) at midnight, 0400, and 0800 on both deprivation days in one cycle, and placebo was given on both days in the other. Results indicated simulator flight performance was maintained by Dexedrine for up to 58 hours, while performance under placebo rapidly deteriorated. The drug was most beneficial

Available in PDF, EPUB and Kindle. Book excerpt: To determine the efficacy and safety of using Dexedrine to sustain aviator performance during periods of sleep deprivation, a placebo-controlled study was conducted. Six U.S. Army helicopter pilots completed five, 1-hour flights in a specially-instrumented UH-60 simulator while their performance was evaluated via a computerized scoring system. Immediately following each flight, data were collected on electroencephalographic (EEG) activity, cognitive/psychomotor performance, and subjective mood ratings. The testing sessions began with flights at 0100, 0500, 0900, 1300, and 1700. One hour prior to each of the first three sessions on the drug-administration days, the aviators were given 10 mg of Dexedrine or placebo. Statistical analyses of the flight maneuvers revealed that Dexedrine improved aviator control on every maneuver with the exception of the hovering turns and the formation flight. Performance on the stationary hovers, the low level navigation, the climbs and descents, straight- and-level segments, standard-rate turns, and the left-descending turn all manifested at least one Dexedrine-related enhancement.

Book Synopsis A New Beginning in Sight by : Eric J Arnott
Download or read book A New Beginning in Sight written by Eric J Arnott and published by CRC Press. This book was released on 2006-11-20 with total page 889 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consultant eye surgeon, Eric Arnott, was one of the original pioneers of small-incision surgery. He was the first to perform modern Phaco surgery in Europe and designed lens implants that have restored the sight to millions of patients. The word autobiography is simply insufficient to describe this book, which is a remarkable testament to the life, works and marriage of a remarkable man. The book details the original invention of the lens implant by Harold Ridley, who Eric worked with in his early years of medical training. It goes on to follow the development of small-incision Phaco surgery, instigated by Charlie Kelman, and the disinterest and contempt held by the peers of these ophthalmologic pioneers. The author describes every advance in this field of ophthalmology in fascinating detail. The importance to Eric of religion, spirituality, family life and helping others less fortunate than himself is reinforced in this enthralling and at times very amusing read. Arnott draws you into his narrative, rousing thoughts of disbelief as you are compelled to continue reading, each new chapter and event in his life proving as fascinating as the last. Entertaining and illuminating, A New Beginning in Sight provides a detailed history of ophthalmology and is essential reading for ophthalmologists, other specialists and non-specialists alike.

Book excerpt: Making decisions is such a regular activity that it is mostly taken for granted. However, damage or abnormality in the areas of the brain involved in decision-making can severely affect personality and the ability to manage even simple tasks. Here, Barbara Sahakian and Jamie Nicole LaBuzetta discuss the process of normal decision making - our strategies for making decisions, biases that affect us, and influential factors - and then describe the abnormal patterns found in patients with conditions such as severe depression, Alzheimer's, and accidental brain damage. Using striking examples and case studies from their own research to show the impact of abnormal decision making, they introduce the concept of 'hot' and 'cold' decision making based on the level of emotions involved, showing that in various psychiatric conditions extreme emotions alter the pattern of decision making. Looking at the ways in which the brain can be manipulated to improve cognitive function in these patients, they consider the use of 'smart drugs' that alleviate these problems. The realization that smart drugs can improve cognitive abilities in healthy people has led to growing general use, with drugs easily available via the Internet. They raise ethical questions about the availability of these drugs for cognitive enhancement, in the hope of informing public debate about an increasingly important issue.

This book was released on 2002 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dextroamphetanmine (Dexedrine) is a stimulant capable of temporarily reversing many of the effects of sleep deprivation. This report substantiates the efficacy of Dexedrine for aviation sustained operations. Specifically it is shown that this countermeasure maintains flight skills psychological mood and physiological activation in sleep-deprived pilots. Dexedrine's positive impact is not offset by marked disruptions In recovery sleep although "lighter sleep" was noted after the drug than after placebo. It is concluded that Dexedrine is a viable remedy for fatigue in aviation sustained operations but it is not a substitute for proper crew-rest scheduling. There is no replacement for adequate restful sleep.

Download or read book Aerospace Health and Safety: Today and the Future written by Irina Mordukhovich and published by Frontiers Media SA. This book was released on 2023-11-20 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aviation plays vital roles in commerce, defense, science and leisure travel. Irrespective of the purpose of flight, crew and passengers are challenged by exposure to a variety of environmental conditions that can differ widely from work and travel environments on the surface of the Earth. With anticipated changes in aviation and space technology, new challenges to health and safety of crew and passengers can be expected. In this Research Topic, we welcome contributions from those whose work and interests are relevant to the health and safety of crew and passengers. This includes, but is not limited to, health and safety professionals, FAA examiners, corporate medical officers, aerospace and occupational physicians, physiologists, military and scientific team members, public health professionals, as well as engineers who are tasked with crew and passenger health and safety design projects. While 4.1 billion passengers fly on commercial airlines annually (and this figure is even higher when taking into account privately owned aircraft and military flight), for the most part aviation is safe. Passengers do arrive at their destinations with little concern to their own well-being and flight is generally well tolerated. However, older flyers, people with (diagnosed or undiagnosed) preexisting disease, and other vulnerable passengers (such as young children and pregnant women) may be at risk of complications and crew may be at special risk due to the frequency and duration of their many flight-related exposures. Health and safety issues for crew and passengers include but are not limited to: potentially severe circadian rhythm disruption, potential health effects of low-level cosmic ionizing radiation exposure at altitude, reduced oxygen delivery and tissue hypoxia at cabin pressurization, cabin air contamination by engine gases, toxic materials used in uniforms and some cabin seat materials, occupational noise, pesticides used for cabin disinsection, lack of adequate crew rest on layovers or between flights, cardiovascular demands of flight and effects of flight-related dehydration, the current absence of screening protocols especially in the context of a rising number of elderly and vulnerable flyers, lack of healthy nutrition at airports and in flight, availability of food and hydration as well as adequate cabin temperature under delay conditions, effects of alcohol use on flight-related physiological and behavioral health risks, anxiety and psychological distress associated with air travel, the effects of long-haul or ultra-long-haul flights on thromboembolic events as well as smoking cessation efforts and related psychological outcomes, job-related stress and harassment among crew. Cosmic ionizing and non-ionizing radiation exposure have drawn attention as have historic exposures of crew and passengers to second-hand cigarette smoke. The threat of political and interpersonal violence and altercations involving aviation cannot be overlooked. On-board medical emergencies run a wide gamut and the capacity to respond becomes more problematic as the duration of flights becomes longer or in the case of flight over oceans and the poles. In addition, in-flight and post flight embolisms and myocardial infarctions are more prevalent than might be expected. We hence encourage manuscripts that address in-flight medical response, including the capabilities on different types of aircraft on potential interventions by crew and medical volunteers. In addition, aviation as a vector for the carriage of disease is a significant concern to public health and security of populations world-wide, and we welcome submissions regarding infectious disease epidemiology and medicine as it relates to air travel. Insects and occasional unplanned travel by birds and rodents can present additional public health concerns. We are approaching an era where space travel may soon be increasingly common. Future flights for near-Earth orbit by leisure travelers and as well as travel to the moon and Mars raise a host of new questions with health and safety implications. What are the proposed health and safety accommodations going to be? Who will be allowed to travel? Perhaps the most interesting question is - who will make the rules?

Available in PDF, EPUB and Kindle. Book excerpt: Taking Precautions Against Fatigue in Aviation Pilot fatigue is a significant problem in modern aviation operations, largely because of the unpredictable work hours, long duty periods, circadian disruptions, and insufficient sleep that are commonplace in both civilian and military flight operations. The full impact of fatigue is often underappreciated, but many of its deleterious effects have long been known. Compared to people who are well-rested, people who are sleep deprived think and move more slowly, make more mistakes and have memory difficulties. These negative effects may and do lead to aviation errors and accidents. In the 1930s, flight time limitations suggested lay-over durations, and aircrew sleep recommendations were developed in an attempt to mitigate aircrew fatigue. Unfortunately, there have been few changes to aircrew scheduling provisions and flight time limitations since the time they were first introduced, despite evidence that updates are needed. Although the scientific understanding of fatigue, sleep, shift work, and circadian physiology has advanced significantly over the past several decades, current regulations and industry practices have in large part failed to adequately incorporate the new knowledge.
