Abstract

A respiratory therapy device generates a flow of breathable gas for therapy. The apparatus may include a flow generator in a housing to generate the breathable gas flow. The flow generator may have an operating voltage for such operations. The device may include a battery pack that is engageable with the housing. The battery pack may be configured to power the flow generator and may include a stand-by circuit configured to switch between stand-by and operating modes. The stand-by circuit may be configured to provide a stand-by operations voltage while in the stand-by mode that is less than an operating voltage of the flow generator and may be configured to detect current demand of the flow generator with the stand-by operations voltage while in stand-by mode such as for enabling an increase voltage from the battery pack to produce the operating voltage in the operating mode for the flow generator.
