Snoring is a common condition affecting up to 60% of the adult population with significant physical and social consequences.95 Waller P.C., Bhopal R.S. Is snoring a cause of vascular disease? Lancet 1989 ; 1 : 143-146 [cross-ref]
Haga clic aquí para ir a la sección de Referencias Nearly all patients with obstructive sleep apnea (OSA) snore, and a significant number of patients who snore may suffer from OSA. OSA has been recognized as a prevalent and important cause of sleep disturbance with dire physical and social consequences if untreated. OSA is characterized by episodes of apnea and hypopnea during sleep. Apnea is defined as cessation of air flow for 10 or more seconds. When respiratory effort remains, the apnea is termed obstructive. Hypopnea refers to a greater than 50% reduction in air flow.20 Fredrickson P.A., Krueger B.R. Insomnia associated with specific polysomnographic findings Principles and Practice of Sleep Medicine, ed 2 Philadelphia: WB Saunders (1994).

Haga clic aquí para ir a la sección de Referencias Minimal criteria for the number of apneas or hypopneas per hour have varied among authors. Currently, more than five apneas or hypopneas per hour is used, most commonly, as minimal criteria for OSA syndrome and is reported as apnea-hypopnea index (AHI). OSA is considered mild if the AHI is 6 to 20, moderate if the AHI is 21 to 50, and severe if the AHI is more than 50.
The prevalence of OSA syndrome in the middle-aged work force is approximately 4% of men and 2% of women.103 Young T., Palta M., Dempsey J. , y al. The occurrence of sleep-disordered breathing among middle-aged adults N Engl J Med 1993 ; 328 : 1230-1235 [cross-ref]
