General Information
Obstructive sleep apnea (OSA) is the most prevalent sleep-breathing disturbance, affecting 24% of men and 9% of women in the general population [1,2].

An estimated 82% of men and 92% of women with moderate-to severe OSA have not been diagnosed.
Sleep Apnea Events
as a complete cessation of breathing (apnea) or a marked reduction in airflow (hypopnea) during sleep, and are considered clinically relevant if they last more than 10 s. The episodes of apneas and hypopneas may persist for 30-60s in some individuals.
Obstructive Sleep Apnea
  • repetitive obstruction of the upper airway often resulting in oxygen desaturation and arousals from sleep
  • excessive daytime sleepiness
  • unrefreshing sleep
  • poor concentration
  • fatigue
OSA is a serious condition that diminishes quality of life and is also associated with many common comorbid conditions. Studies have shown that patients with OSA will have an increased incidence of:
  • coronary artery diseases
  • hypertension
  • congestive heart failure
  • cerebrovascular accidents
  • gastroesophageal reflux disease
It is estimated that the average life span of a patient with untreated OSA is 58 years, much shorter than the average life span of 78 years for men and 83 years for women.
