Types of


Sleep Apnea

Obstructive sleep apnea (OSA) is a common disorder resulting from the collapse of the pharyngeal airway during sleep.

It is estimated that one in five adults has some form of obstructive sleep apnea.

OSA has been associated with many medical comorbidities, obesity and surgical mortality.


Insomnia is the inability to fall asleep or stay asleep.

It is estimated that 50% of Americans have experienced insomnia at some point in their lives.

Approximately 10% of Americans suffer from chronic insomnia.

Restless Leg Syndrome

RLS is a neurological disorder characterized by an irresistible urge to move one's body to stop uncomfortable or odd sensations.

RLS affects an estimated 7-10% of the general population in North America.


Neurological chronic sleep disorder characterized by excessive sleepiness and sleep attacks at inappropriate times.

In the United States, it is estimated that this condition afflicts as many as 200,000 Americans but fewer than 50,000 are diagnosed.


Category of sleep disorders that involve abnormal and unnatural movements, behaviors, emotions, perceptions, and dreams that occur while falling asleep, sleeping, between sleep stages, or during arousal from sleep.



  • Obstructive sleep apnea (OSA) is estimated to affect approximately 20% of the American population (60 million lives).


  • It is estimated that less than 10% of those with OSA have been diagnosed which leaves a large patient population that needs to be treated.


  • Sleep apnea can result in high blood pressure, stroke, congestive heart failure, and even death. A national survey found that 69% of American adults fail to recognize sleep as a critical factor in maintaining health.


  • Recent studies have shown that in the pre-surgical population, approximately 40% of the patients have a high risk for OSA.


  • In one specific study, patients who had a high risk of OSA had a 19.6% postoperative complication rate as compared to 1.3% for those with low OSA risk.


  • A large study of approximately 50,000 patients with OSA undergoing surgery reported a fivefold increase in intubation and mechanical ventilation after orthopedic surgery compared to a twofold increase after general surgery.


  • Gupta and colleagues found that patients with OSA undergoing hip or knee replacement were at an increased risk of developing perioperative complications 29% vs. 9% in the general population.
