Abstract: There is an apparatus including a mandible positioner for positioning the mandible of a patient with respect to the maxilla of the patient and a breathing assistance apparatus. The breathing assistance apparatus has a sensor arranged to detect at least one element representative of a breathing state of the patient. A source of breathing gas includes a patient interface and has at least a first operable position and a second operable position. The source of breathing gas provides a different ratio of carbon dioxide and oxygen to the patient when in the first operable position than in the second operable position. The source of breathing gas may be moved between the first operable position and the second operable position in response to signals from the sensor. For example, the source of breathing gas may provide rebreathed air to the patient in the first position and atmospheric air in the second position.

Abstract: A method for modifying the breathing of a patient while the patient is experiencing sleep apnea, for example Cheyne Stokes breathing. An instantaneous pulmonary ventilation of a patient is monitored. Limit cycle behavior of the instantaneous pulmonary ventilation is identified. A transient intervention is applied to the patient during a phase of a limit cycle of the instantaneous pulmonary ventilation. The transient intervention has an effect on a breathing state of the patient.

Abstract: A system for reducing central sleep apnea (CSA) is described in which certain methods of increasing a patient's rebreathing during periods of the sleep cycle are used. By increasing rebreathing during periods of overbreathing, the over-oxygenation which typically results from the overbreathing period can be reduced, thus reducing the compensating underbreathing period and effectively reducing the loop gain associated with the central sleep apnea. Nasal occlusion and a leak resistant oral interface provide control for gas leaks from a patent interface.

Abstract: The present invention relates to systems and methods for automatically and continuously regulating the amount of mandibular displacement to an optimal value during obstructive sleep apnea treatment. Obstructive sleep apnea therapy is implemented by a device which automatically reevaluates an applied mandibular displacement and continually searches for a minimum displacement required to adequately distend a patient's pharyngeal airway. The minimum optimal displacement varies with body position, stage of sleep throughout the night, the patient's body weight, and whether alcohol or sleeping medicine has been ingested.

Abstract: A remote-controlled mandibular positioner for conveniently and precisely positioning the mandible during a sleep center or in-hospital study of patients who are candidates for mandibular positioner therapy. The remote-controlled mandibular positioner is used during sleep to perform a therapeutic titration study during full polysomnographic monitoring to determine the mandible position effective in treating obstructive sleep apnea. During the titration study, the mandible is advanced by a technician using the remote-controlled mandibular positioner until all apneas and hypopneas are eliminated. The titration study determines whether a mandibular positioner will be effective in treating a particular patient, and if so, the degree of mandibular ventral displacement required for effective treatment of obstructive sleep apnea.

Abstract: A nasal adaptor device and seal for delivering gases under pressure to the nasal airway of an individual including an aerodynamically contoured manifold to receive gases from an inlet and to divide the gases for flow to a pair of flange members, preferably having a non-spherical curved "egg-shaped" surface, which members are, complementary to the nares of an individual without cannulating the nares to provide a seal to withstand positive pressure of gases to be distributed to the nasal airways. The devices and nares seals of this invention are especially useful in treatment of obstructive sleep apnea and in ventilation of individuals for whom positive pressure ventilation is indicated.
