Book Description
This study examined the effectiveness of a planned cockpit rest period to improve alertness and performance in long-haul flight operations. The Rest Group (12 crew members) was allowed a planned 40 minute rest period during the low workload, cruise portion of the flight, while the No-Rest Group (9 crew members) had a 40 minute planned control period when they maintained usual flight activities. Measures used in the study included continuous ambulatory recordings of brain wave and eye movement activity, a reaction time/vigilance task, a wrist activity monitor, in-flight fatigue and alertness ratings, a daily log for noting sleep periods, meals, exercise, flight and duty periods, and the NASA Background Questionnaire. The Rest Group pilots slept on 93 percent of the opportunities, falling asleep in 5.6 minutes and sleeping for 25.8 minutes. This nap was associated with improved physiological alertness and performance compared to the No-Rest Group. The benefits of the nap were observed through the critical descent and landing phases of flight. The nap did not affect layover sleep or the cumulative sleep debt. The nap procedures were implemented with minimal disruption to usual flight operations and there were no reported or identified concerns regarding safety. Rosekind, Mark R. and Graeber, R.

Book Description
A unique resource on sleep medicine Written by contemporary experts from around the world, Sleep: A Comprehensive Handbook covers the entire field of sleep medicine. Taking a novel approach, the text features both syndrome- and patient-oriented coverage, making it ideally suited for both clinical use and academic study. Sleep: A Comprehensive Handbook begins with a brief introduction to the basic science of sleep, from neurobiology to physiologic processes. This leads into sections offering comprehensive coverage of insomnia, sleep apnea, narcolepsy, parasomnias, movement disorders, and much more. Sleep and related disorders are also discussed, followed by chapters on considerations for special patient groups. Special materials for practitioners include a sample interview and questionnaire as well as a chapter on operating and managing a sleep center. The text concludes with discussions of sleep assessment methods such as polysomnography, actigraphy, and video EEG monitoring. With full coverage of over 100 key topics in sleep medicine, Sleep: A Comprehensive Handbook offers the most practical, thorough, yet handy resource available on adult and pediatric sleep medicine. Praise from the reviews: "...no other publication in the field can begin to compare with the breadth or depth of the 'Handbook'...I cannot imagine a functioning sleep disorders clinic without at least one copy on standby as a ready reference." PscyCRITIQUES "Sleep: A Comprehensive Handbook is a first-rate textbook with concise, up-to-date information covering a wide range of subjects pertinent to the practice of sleep medicine."

Book Description
This book brings the neurosciences to operational and clinical aviation medicine. It is concerned with the physiology and pathology of circadian rhythmicity, orientation, hypotension and hypoxia, and with disorders of the central nervous system relevant to the practice of aviation medicine. The chapters on circadian rhythmicity and orientation deal with the impaired alertness and sleep disturbance associated with desynchrony and with the effects of linear and angular accelerations on spatial awareness. Hypotension and hypoxia cover cerebral function during increased gravitational stress, clinical aspects of exposure to acute hypoxia, the mild hypoxia of the cabin of transport aircraft, adaptation and acclimatization to altitude and decompression at extreme altitudes and in space. Disorders of particular significance to the practice of aviation medicine such as excessive daytime sleepiness, epilepsy, syncope, hypoglycaemia, headache and traumatic brain injury are covered, while neuro-ophthalmology, the vestibular system and hearing also receive detailed attention. The potentially adverse effects of the aviation environment and of disorders of the nervous system are brought together, and the text covers the neurological examination as it relates to aircrew and explores current management and therapeutics. The Neurosciences and the Practice of Aviation Medicine is an essential work for those involved in the practice of aviation medicine where familiarity with the effects of the aviation environment on the nervous system and understanding the pathophysiology of relevant clinical disorders are of prime concern. The authors from leading centres of excellence are physiologists concerned with the aviation environment and physicians involved in the day-to-day practice of medicine. They bring to this authoritative text wide experience and expertise in both the experimental and clinical neurosciences.
