Obstructive sleep apnea is an serious,sometimes fatal,illness characterized by snoring, partial or complete cessation of breathing during sleep, reductions in blood oxygen levels, severe sleep fragmentation, and excessive daytime sleepiness. Researchers and clinicians have recognized sleep apnea as one of the most common sleep disorders and with perhaps the greatest medical and social impact on society in terms of morbidity and mortality. The syndrome strikes both sexes and all races, ages, and ethnic groups, though it is less common in women prior to menopause, and may possibly be more common in blacks than in whites. The potential consequences of obstructive sleep apnea are significant and include hypertension,feeling unwell, coronary heart disease, myocardial infarction, pulmonary hypertension, congestive hear failure, stroke, neuropsychiatric problems, cognitive impairment, sexual disfunction, and injury due to accidents. It is estimated that cardiovascular deaths attributable to obstructive sleep apnea alone may be as high as 38,000 annually. In the United States,{12 MILLION} people between the ages of 30-60 are estimated to have obstructive sleep apnea, nearly one-quarter of them experience the disorder at a moderate or severe level.

Newly discovered phenomenon called complex sleep apnea.
The newly discovered complex sleep apnea, is a combination of both obstructive and central sleep apneas.

Western men with a neck circumference greater than 16.929 inches were shown to have a high incidence of sleep apnea and these results may apply to Asian patients.

Patients with complex sleep apnea at first appear to have obstructive sleep apnea and stop breathing 20 to 30 times per hour each night.
But unlike typical obstructive sleep apnea patients, their breathing problem is not completely alleviated by a CPAP machine, which forces air into the patient’s airway.
Instead, once the CPAP is applied to complex sleep apnea patients, the obstruction seems to dissipate, but still they do not breathe properly.
Symptoms of central sleep apnea then appear and fragmented sleep results, due to frequent pauses in breathing.
