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.

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.

    - 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.
