Term Papers on Sleep Apnea
Sleep Apnea General Psychology Steven O'Brien, Psy.D Sleep, why do people sleep at all? Why can't we just stay awake? Some biologist suggest that sleep provides the opportunity to conduct self-repair and purge the body of it's waste that has built up during the day's activity. Nevertheless, the body is capable of repairing itself and disposing of wastes during waking hours, so sleep in a way really isn't necessary for routine maintenance (e.g., urinating, etc.). Dr. Quentin Regestein, lead sleep and sleep disorders researcher at Harvard Medical School also believed that sleep kept our distant ancestors out of harms way during the night when they could not see as well as their night roaming predators. Sleep is regulated by a connected series of structures in the deep midline areas, and along other way stations that extend through the central axis of the brain, these structures relay information about things that affect sleep. In Dr. Regestein notes, he spoke of experiments that were performed by researchers. The researchers he spoke of would destroy specific brain structures of a lab animal and then note how the animal slept. For instances, in one lab animal the researcher cut through the axis of the brain at one level, which would prevented the animal from awakening; showing that brain structures below the level of the cut were responsible for awakening the lab animal. The American Sleep Disorders Association (ASDA), Association for the Psychophysiological Study of Sleep (APSS), Association of Sleep Disorder Centers (ASDC), and the American Psychiatric Association (APA) has studied sleep and sleep disorders since the early 1970's. Out of all the sleep disorders currently being studied, sleep apnea has gain world wide attention, affecting over 15 million people. Apnea, derived from the Greek word "want to breath." Sleep Apnea (cessation of air flow at the mouth for greater than 10 seconds) can reflect 1) loss of central nervous system drive to maintain ventilation, 2) mechanical upper airway obstruction, or combinations of both. The second edition of Anesthesia and Co-Existing Disease states "Conversely, obstructive forms of sleep apnea are due to an abnormal relaxation of the posterior pharyngeal muscles" - there is persistence of respiratory movements, but airflow is absent due to upper airway obstruction. Study shows awakening occurs when the arterial partial pressure of carbon dioxide rise or oxygen falls. Severe apnea, which affects about 1 percent of the general adult population, often results in 400-500 awakenings a night. Moreover, depending on the severity and the number of episodes of sleep apnea, the patient's daily life and survival can be greatly endangered. According to the Wisconsin Sleep Cohort Study, over an eight-year period, a 37 percent death rate has been reported among persons with apnea (20 episodes or more per hour). The Wisconsin Sleep Cohort Study also reported sleep apnea is more likely to occur in men then women, for the male hormone, testosterone is believed to be related to sleep apnea. Admittedly, researchers believe a female hormone, progesterone stimulates respiration and therefore may help prevent breathing problems. In the Wisconsin Sleep Cohort Study, the researchers noted a strong link between smoking and sleep apnea. Smokers that smoked 40 or more cigarettes a day had the greatest risk of developing sleep apnea then patients who had never smoked. The medical community has yet to fully understand the intra play of factors producing the sleep apnea syndrome. Sleep affects psychological well-being. Because sleep apnea deprives patients of sleep, numerous of studies have consistently shown that sleep loss affects daytime performance, sleepiness and mood. One of the first capacities that Dr. Arthur J. Speilman of the Department of Psychology in New York spoke of, is the ability to produce creative solutions to problems., and how being deprive of sleep can impair a patients fun...
