Breathing apparatus with multiple power sources

A breathing apparatus includes components that allow different operations of the apparatus with different power sources. For example, a respiratory therapy device for controlling respiratory therapy may include a power input circuit to receive a first power or a second power. The first power may be provided by a connectable low power source, and the second power may be provided by a connectable high power source. A controller of the breathing apparatus coupled to the power input circuit may be configured to detect one of the power sources and selectively activate one of a first mode of operation and a second mode of operation based on the detection. The first mode of operation may be a non-treatment mode having a first power, such as for data setting or data transfer with a respiratory treatment device, and the second mode of operation may be a treatment mode having a second power. 一种呼吸设备包括允许利用不同电源对设备进行不同操作的部件。例如，用于控制呼吸治疗的呼吸治疗设备可以包括功率输入电路以接收第一功率或第二功率。第一功率可以由可连接的低功率电源提供,并且第二功率由可连接的高功率电源提供。联接到功率输入电路的呼吸设备的控制器可以配
