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, 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.
