Abstract: Embodiments of gas concentrating systems and methods are provided. In one embodiment, the system includes, for example, a plurality of modules connectable and disconnectable from each other to thereby adjust the (gas) capacity and modality of the connected system. In this manner, a user need not maintain one system for on the go (ambulatory) scenarios and a wholly second system for stationary (e.g., at home) scenarios. The systems and methods further provide the ability to gradually upgrade the system capacity consistent with the user's lifestyle and medical needs.

Abstract: Systems and methods are provided for displaying status of a gas concentrator. The systems and methods include, for example, a display having a plurality of illuminable segments. The illuminable segments can be illuminated to form one or more displays indicating system status. The system status includes, for example, warmup, normal operation, low priority alarm(s), high-priority alarms, etc. In one embodiment, the systems and methods also read oxygen values of the gas concentrating system as one basis for determining system status. Other bases are also disclosed.
