VENTILATION STABILIZATION SYSTEM
First Claim
1. An apparatus, comprising:
- a mandible positioner for positioning the mandible of a patient with respect to the maxilla of the patient, the patient having a breathing state; and
a breathing assistance apparatus comprising;
a sensor arranged to detect at least one element representative of the patient'"'"'s breathing state;
a source of breathing gas including a patient interface and having at least a first operable position and a second operable position, the source of breathing gas being configured to provide a different ratio of carbon dioxide and oxygen to the patient when in the first operable position than in the second operable position; and
the source of breathing gas being movable between the first operable position and the second operable position in response to signals from the sensor.

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. An apparatus for interfacing with a patient to allow breathing gas to be provided to the patient is also provided.

9. A method for assisting the breathing of a patient, comprising the steps of:
-
protruding the mandible of a patient with a mandibular protrusion device; detecting the breathing of a patient; determining whether abnormal breathing conditions are present; and changing an amount of carbon dioxide concentration provided to the patient when abnormal breathing conditions are determined to be present. - View Dependent Claims (10, 11)

12. An apparatus for assisting the breathing of a patient having a breathing state, the apparatus comprising:
-
a mandibular positioning device; an interface adapted to provide breathing gas to a breathing orifice of the patient; a sensor attached to the interface, the sensor detecting at least one element representative of the patient'"'"'s breathing state; a fluid manifold connected to an exterior gas source, the fluid manifold connected to the interface; an exit connected to the interface; and a valve operably connected to the sensor to vary the amount of flow of exhaled gases from the patient into the fluid manifold. - View Dependent Claims (13)

14. An apparatus for assisting the breathing of a patient having a breathing state, the apparatus comprising:
-
a mandibular positioning device; an interface adapted to provide breathing gas to a breathing orifice of the patient; a fluid manifold connected to the interface; a sensor attached to the fluid manifold, the sensor detecting at least one element representative of the patient'"'"'s breathing state; and an exterior pressurized gas source connected to the interface and providing gas with a higher content of oxygen gas than atmospheric air to the patient in response to signals from the sensor.

15. An apparatus for interfacing with a patient to allow breathing gas to be provided to the patient, the apparatus comprising:
-
a mandibular positioning device for positioning the mandible of a patient with respect to a maxilla of the patient;
the apparatus further comprising feature A or feature B or both feature A and feature B;where feature A comprises a nasal interface having a nose seal, an oral interface having a mouth seal, and a gas passage through at least one of the nasal interface and the oral interface through which breathing gas can be provided to the patient; and where feature B comprises an oral interface having a mouth seal comprising an internal flange for sealing around an interior of the mouth, and an external flange for sealing around an exterior of the mouth. - View Dependent Claims (16, 17, 18, 19, 20, 21)
