Abstract
No abstract available. Article truncated after 150 words. Obstructive Sleep Apnea (OSA) is a life-altering disease with a prevalence of 10% in men and 9% in women (1). In some groups (severe obesity, BMI > 40 kg/m2) the prevalence may be as high as 40% (2). One of the most controversial areas in the field of sleep medicine for many years has been the definition of the syndrome. Investigators who first identified OSA created the apnea index (AI), the number of apnea events per hour. An apnea was defined as a complete cessation of airflow for at least 10 seconds. When continuous positive airway pressure (CPAP) treatment for OSA was first introduced, a definition that third-party payors, such as the Center for Medicare and Medicaid Services (CMS), could use to determine which patients qualified for treatment was needed. The definition at that time was 30 apnea events during a 6-hour recording, which corresponded to an AI of 5 …
