and tongue forward. The negative pressure is created by a bedside console connected by a small tube to a mouthpiece worn inside the mouth during sleep. The device is successful in between a quarter and a third of people.

Medical uses

While oral pressure therapy resulted in some benefit, most people were not fully treated by its use. The device was successful in between a quarter and a third of people.

Contraindications

Oral pressure therapy should not be used to treat

central sleep apnea Central sleep apnea (CSA) or central sleep apnea syndrome (CSAS) is a sleep-related disorder in which the effort to breathe is diminished or absent, typically for 10 to 30 seconds either intermittently or in cycles, and is usually associated w ...

, oral pressure therapy does not apply pressure directly to the airway, but applies light negative pressure in the oral cavity. With this system, the user breathes normally through the nose with the mouth closed. Unlike mandibular repositioning devices (also known as oral appliances and dental devices), oral pressure therapy does not pull the lower jaw forward.
