Abstract:
1. An apparatus, comprising: a flow generator for providing pressurized air, a humidifier in communication with the flow generator to add humidity to the pressurized air; a user interface in communication with at least one of the flow generator and the humidifier to receive pressurized and humidified air and configured to provide a positive pressure therapy; a battery coupled to the humidifier and the flow generator to provide power to the flow generator and humidifier; and a control unit coupled to the battery to monitor current drawn from the battery, the control unit configured to calculate a remaining battery operation time based on the drawn current, and the control unit being coupled to at least to one of the humidifier and the flow generator and adapted to modify current drawn by at least one of the humidifier and the flow generator to reduce a total current drawn from the battery when the remaining battery operation time is insufficient to sustain the positive pressure therapy over a predetermined therapy time.
