Abstract: The present technology is directed to systems and methods for generating concentrated oxygen for therapeutic purposes. For example, in some embodiments the systems described herein include an oxygen assembly that can provide pulses of oxygen and/or a continuous flow of oxygen to a patient. The oxygen assembly can include one or more media or adsorption beds configured to generate concentrated oxygen from ambient air, such as by removing nitrogen from ambient air flowing through the media bed. The one or more media beds can be removed from the system to facilitate replacement of the media bed by a user. The oxygen assemblies and media beds described herein can also include various additional features that are expected to improve the oxygen generation process and/or the operation of the oxygen generating systems.

Abstract: The present technology is directed to ventilator systems that can provide both ventilation therapy and oxygen therapy. The systems described herein may include a ventilation assembly that can provide inspiratory gas to a patient circuit and an oxygen assembly that can provide pulses of oxygen to an oxygen delivery circuit. In some embodiments, the oxygen delivery circuit is distinct from the patient circuit. For example, the patient circuit can include a corrugated conduit coupled a ventilation mask, and the oxygen delivery circuit can include a nasal cannula. The ventilation mask can be positioned over the nasal cannula so that the patient can receive both the inspiratory gases and the pulses of oxygen.
