• Obstructive Sleep Apnea (OSA) is a debilitating, often life-threatening sleep disorder.
• OSA is extremely common: 24% of adult men and 9% of adult women.
• Prevalence is similar to diabetes or asthma.
• Mild OSA becomes more severe with time.
  Mild:          AHI 5–15
  Moderate:  AHI 15–30
  Severe:     AHI >30
  AHI = Apnea Hypopnea Index, number of events (>= 10 seconds) per hour of sleep
• An estimated 38 million Americans have OSA, with 15 million moderate to severe OSA.
• Approximately 25% are being treated.
• Approximately 1 million patients being diagnosed per year in the USA.
• Loss of tongue muscle tone during sleep causes the obstruction in most patients with OSA.
• Continuous Positive Airway Pressure (CPAP) device is the established therapy.
• More than 4 million patients have CPAP machines in North America.
• Studies have shown that more than 46% do not comply with CPAP.
