With weight loss, SDB symptoms diminish. With age, muscles in the pharyngeal area atrophy, thus increasing obstruction. CNS depressants and muscle relaxants may have a counterproductive sedative or relaxant effect. Proper sleep hygiene is desirable, with 8 hours total sleep time considered optimal. Maintenance of a consistent sleep schedule also mitigates problems.
Obstruction is more prevalent in a supine position.
In 38 of 75 patients, OSA was abolished with the device alone. Three nonapneic snorers had unchanged scores. No correlation with age was noted. A variety of treatments are available, depending on disease severity, patient anatomy, and natural inclination with regard to treatment. Some patients are claustrophobic and cannot use CPAP but can tolerate OAs.
