A remote-control assembly for adjusting a flow of oxygen from an oxygen concentrator includes an inducer module and remote controller. The inducer module, which comprises a receiver, is selectively couplable to the oxygen concentrator so that the inducer module is operationally coupled to a flow rate control knob of the oxygen concentrator. The remote controller comprises a transmitter and is positioned to selectively and wirelessly communicate a command to the inducer module, via the receiver, positioning the inducer module to turn the flow rate control knob to adjust a flow of oxygen from the oxygen concentrator.
