Abstract
Systems and methods for controlling breathing of a patient to maintain specified levels of CO2 in arterial blood. In one exemplary embodiment a respiratory conduit is configured to be coupled at one end to a patient interface device that is, in turn, coupled to the patient's breathing airway. The respiratory conduit is configured at the opposing end to be coupled to a pressurized air generating device. A control device is positioned in the respiratory conduit between the patient interface device and the pressurized air generating device and includes one or more vent apertures that allow a predetermined amount of exhaled air from the patient to escape from the respiratory conduit while retaining a predetermined fraction of the exhaled air to reintroduce to the patient during the next inhale. In this manner the system provides for a predetermined percentage of CO2 to be rebreathed by the patient.
