Abstract: A patient interface may include a plenum chamber pressurisable to a therapeutic pressure, the plenum chamber further comprising two plenum chamber connectors; a seal-forming structure constructed and arranged to seal with a region of the patient's face; positioning and stabilising structure comprising two conduits configured to connect to a corresponding one of the plenum chamber connectors; a vent assembly having a plurality of vent holes configured to allow a continuous flow of gases exhaled by the patient from within the plenum chamber to ambient throughout the patient's respiratory cycle; and a heat and moisture exchanger (HMX) assembly including an HMX frame and a material positioned on the HMX frame, the material being supported by the HMX frame such that at least a portion of the flow of air entering the plenum chamber from the plenum chamber connectors passes through the material before entering the patient's airways.

Abstract: A humidifier for humidifying a flow of pressurized breathable gas to be delivered to a patient includes a dock and a humidification tub. The dock includes a device compartment that is configured to at least partially removably receive an RPT device that is configured to supply the flow of pressurized breathable gas. The dock also includes a humidification compartment that is fluidly connected to the device compartment. The humidification tub is configured to contain a supply of water and is at least partially removably received within the humidification compartment so that, in an operational configuration, the humidification tub is arranged to receive the flow of pressurized breathable gas and output the flow of pressurized breathable gas with increased humidity. The dock also includes a heater fixed to the humidification tub. The heater is configured to heat the supply of water.

Abstract: An apparatus for treatment of a respiratory condition, the apparatus comprising: a pressure generator configured to generate a flow of breathable gas; an intermediate component pneumatically connected to an air delivery tube, the intermediate component comprising a port configured to facilitate propagation of sound outside of the intermediate component; a sensor attached externally to the intermediate component and located adjacent to the port of the intermediate component, the sensor configured to sense sound propagated through the air delivery tube; and a controller. The controller can be configured to: receive a sound signal generated by the sensor as a result of sensing sound during operation of the apparatus, analyse the received sound signal, and effect a response based at least in part on the analysing.
