This book was released on 2006 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whilst a substantial amount of research has demonstrated the negative impact of sleep deprivation on human performance, studies looking at recovery of performance following sleep deprivation are limited. The current study examined recovery of performance following two nights deprivation where recovery opportunity was restricted to 6 hours each night over five nights. Following sleep deprivation it was hypothesised that (a) performance would not recover to baseline levels, and (b) different performance tasks would vary in how they recovered. Eleven healthy subjects aged 19 to 24 years were recruited and remained in the laboratory for nine consecutive nights: an adaptation and baseline night with 9 hours time in bed (TIB) from 2300 to 0800; two nights of sleep deprivation (SD) culminating in 66 hours of sustained wakefulness (SW); followed by five nights recovery sleep with 6 hours TIB from 0200 to 0800. During the experimental period subjects were tested on performance tasks every two hours for approximately 30 minutes. These included the Psychomotor Vigilance Task (PVT), measuring sustained attention, and three other tasks including Stroop, measuring cognitive interference; Serial Addition, measuring mental arithmetic and Six Letter Search, measuring working memory. Across the recovery period PVT performance remained impaired, stabilising at lower than baseline levels and failing to recover. In contrast, recovery of the other tasks occurred by the second recovery day. The PVT is highly sensitive to the effects of sleep loss, and is considered to be a basic indicator of sleepiness. Therefore, results indicate that even after five restricted recovery sleep opportunities subjects were still sleepy, albeit at stabilised levels. For the remaining more complex tasks, results may indicate a functional recovery with limited sleep. However, learning effects may have influenced the results on these tasks. Overall, results suggest that more complex tasks may recover more quickly from the effects of sleep loss.

Download or read book Resident Duty Hours written by Institute of Medicine and published by National Academies Press. This book was released on 2009-04-27 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medical residents in hospitals are often required to be on duty for long hours. In 2003 the organization overseeing graduate medical education adopted common program requirements to restrict resident workweeks, including limits to an average of 80 hours over 4 weeks and the longest consecutive period of work to 30 hours in order to protect patients and residents from unsafe conditions resulting from excessive fatigue. Resident Duty Hours provides a timely examination of how those requirements were implemented and their impact on safety, education, and the training institutions. An in-depth review of the evidence on sleep and human performance indicated a need to increase opportunities for sleep during residency training to prevent acute and chronic sleep deprivation and minimize the risk of fatigue-related errors. In addition to recommending opportunities for on-duty sleep during long duty periods and breaks for sleep of appropriate lengths between work periods, the committee also recommends enhancements of supervision, appropriate workload, and changes in the work environment to improve conditions for safety and learning. All residents, medical educators, those involved with academic training institutions, specialty societies, professional groups, and consumer/patient safety organizations will find this book useful to advocate for an improved culture of safety.

Available in PDF, EPUB and Kindle. Book excerpt: Clinical practice related to sleep problems and sleep disorders has been expanding rapidly in the last few years, but scientific research is not keeping pace. Sleep apnea, insomnia, and restless legs syndrome are three examples of very common disorders for which we have little biological information. This new book cuts across a variety of medical disciplines such as neurology, pulmonology, pediatrics, internal medicine, psychiatry, psychology, otolaryngology, and nursing, as well as other medical practices with an interest in the management of sleep pathology. This area of research is not limited to very young and old patientsâ€"sleep disorders reach across all ages and ethnicities. Sleep Disorders and Sleep Deprivation presents a structured analysis that explores the following: Improving awareness among the general public and health care professionals. Increasing investment in interdisciplinary somnology and sleep medicine research training and mentoring activities. Validating and developing new and existing technologies for diagnosis and treatment. This book will be of interest to those looking to learn more about the enormous public health burden of sleep disorders and sleep deprivation and the strikingly limited capacity of the health care enterprise to identify and treat the majority of individuals suffering from sleep problems.

Download or read book Recovery of Sleep Performance and Mood Following 38 Hours of Sleep Deprivation Using Naps as a Countermeasure written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In certain situations, soldiers must continue to perform their duties over an extended period of time, knowing that their regular sleep period will be missed and their time awake will extend well past 24 hours. Although equipment may be able to operate over extended work hours, personnel are not capable of continuing for days without proper rest and recovery. However, during the times when extended work hours are required, soldiers must find a way to maintain alertness in order to carry out their duties. When one chooses a countermeasure to aid soldiers' performance, the decision is based on how well the method will increase alertness and performance. However, one must also examine how a person will recover from the countermeasure, how long it will take before he/she is ready to continue the work schedule, and what consequences will occur due to the countermeasure. Many studies are aimed at how well countermeasures work in the short run, but neglect to examine the aftereffects.

Book excerpt: An ever-increasing number of military personnel and civilians alike must work daily without adequate sleep. Although considerable data show that sleep deprivation alters many aspects of behavior, little is known about changes in the brain substrate underlying the behavioral effects, and even less is known about the cerebral effects of recovery sleep. The overarching objective of this study is to investigate the effects of 2 full nights of sleep loss (66 hours total) and 2 full nights of recovery sleep on cognitive performance and brain function. We have studied 40 individuals for 6 nights and 6 days. Over the course of this period, subjects received 4 polysomnograms and 10 functional magnetic resonance imaging (FMRI) sessions. During the FMRI sessions, functional brain imaging data was collected while subjects performed each of 3 cognitive tasks. These data provide a rich amount of information concerning the effects of prolonged total sleep deprivation and recovery sleep on cognitive performance and the cerebral underpinnings of that performance. Early analyses of these data are revealing the course of deterioration and recovery in cognitive performance, the specific component processes of cognition affected by sleep deprivation, and the changes in brain function associated with sleep deprivation. We have also initially reported distinct patterns of recovery for different sleep parameters after sleep deprivation, and the possibility of using the FMRI measures to identify neural correlates of vulnerability and resilience to sleep deprivation.
