First Claim
1. A device for treating sleep disordered breathing and diabetes comprising:
- at least one sensor detecting a physiological signal and transmitting physiological data to a controller; and
a controller to control an air flow generator to provide pressurized air to a patient according to a first treatment protocol, and wherein said controller is adapted to determine a blood glucose level from the physiological data and to change to controlling the air flow generator to provide pressurized air according to a second treatment protocol based on the determined blood glucose level, wherein the first treatment protocol controls pressure to generally remain constant over a breathing cycle of the patient, and wherein the second treatment protocol controls the pressure to vary over the breathing cycle of the patient and comprises initiating target ventilation control.

Abstract
A respiratory treatment apparatus (1) provides blood glucose monitoring and breathing control based on detected blood glucose information. In an example embodiment, a flow generator provides a flow of breathable gas at a pressure above atmospheric to a patient interface according to a pressure treatment control protocol such as a CPAP, APAP, bi-level CPAP, etc. A detector determines a blood glucose condition indicator with one or more sensors that are used to sense physiological information. In response to signals from the sensors, a controller, such as a digital signal processor, controls adjustments to the flow of breathable gas provided by the flow generator. The adjustments are determined by the controller based on the detected blood glucose indicator and/or changes thereto.
