SLEEP APNEA Essay -- essays research papers

SLEEP APNEA What is Sleep Apnea? The Greek word "apnea" literally means "without breath." There are three types of sleep apnea: obstructive, central, and mixed; of the three, Obstructive Sleep Apnea (OSA) is the most common. Despite the difference in the root cause of each type, in all three, people with untreated sleep apnea stop breathing repeatedly during their sleep, sometimes hundreds of times during the night and often for a minute or longer. Obstructive sleep apnea is caused by a blockage of the airway, usually when the soft tissue in the rear of the throat collapses and closes during sleep. In central sleep apnea, the airway is not blocked but the brain fails to signal the muscles to breathe. Mixed sleep apnea is a combination of the two. With each apnea event, the brain briefly awakes sleep apnea victims from sleep in order for them to resume breathing, therefore sleep is extremely fragmented and of poor quality. Sleep apnea is very common and affects more than twelve million Americans. Risk factors include being male, overweight, and over the age of forty, but sleep apnea can strike anyone at any age, even children. Yet still because of the lack of awareness by the public and healthcare professionals, the vast majority remain undiagnosed and therefore untreated, despite the fact that this serious disorder can have significant consequences. Untreated, sleep apnea can cause high blood pressure and other cardiovascular diseases, memory problems, weight gain, impotency, and headaches. Moreover, untreated sleep apnea may be responsible for job impairment and motor vehicle crashes. Fortunately, sleep apnea can be diagnosed and treated. Several treatment options exist, and research into additional options continues. How is Sleep Apnea treated? There is currently no proven drug therapy for sleep apnea. However, there are 4 basic approaches to treatment, which are not mutually exclusive: 1. Modification of circumstances which may be causing sleep apnea or making it worse. This would include weight loss, avoidance of alcohol and sedative drugs, trying to sleep only on your side and stopping smoking. It would also help to improve nasal breathing if this problem exists; sometimes this can be done with some simple medication and occasionally it requires an operation. Finally it is important to avoid sleep deprivation. 2. Use Contin... ...y and which therapy in particular. The Evaluation Process An evaluation at the Sleep Disorders Center begins with an initial consultation with the director of the Center. In many instances, one visit is sufficient for a diagnosis to be made and a treatment plan formulated. For some patients, however, more extensive testing is required. If an all-night sleep study is required, it is performed at our laboratory in The Presbyterian Hospital /Columbia-Presbyterian Medical Center. The all-night sleep study is a safe and completely painless technique by which physiological functions in sleep are measured. Patients spend one or more nights in a private and comfortable laboratory during which a series of measurements are taken with sophisticated monitoring devices. Patients arrive at the laboratory in the evening and leave the following morning; it is usually not necessary to miss a day of work. In the course of your night at the sleep laboratory, over 1000 pages of data are collected, along with a complete video-tape record. This data is thoroughly reviewed by our expert staff and when necessary, by additional consultants. A detailed final report is usually ready within one week.
