The base member includes a plurality of segments configured to facilitate the close nesting or alignment of multiple portable intravenous stands; and thus reducing the amount of space required for storing the portable intravenous stands when not in use. The hydrogen concentration cell has a first gas diffusion electrode, a second gas diffusion electrode and a proton conductive membrane therebetween. The source of the depletion mode FET is serially coupled to the drain of the enhancement mode FET. , awaiting deployment, an asset descriptor manifest is received from the distribution server.
