The present technology relates to systems and/or methods for enabling a respiratory device to be configured when a clinician or healthcare professional is remote from the respiratory device. One form provides a method of configuring a respiratory device, the respiratory device comprising a processor configured to control operation of the respiratory device in accordance with a plurality of operating parameters. The method comprises determining a combination of settings for the device from an identifier sent to the device, the identifier corresponding to the combination of settings, and configuring the respiratory device accordingly. Another form provides a method of verifying the configuration of the respiratory device by outputting an identifier corresponding to the combination of settings for the device, and determining the settings from the identifier.

The presently disclosed embodiments relate to devices and methods for efficiently removing the nitrogen dioxide (NO.sub.2) from a gas stream while enhancing the concentration of nitric oxide (NO) in the gas stream without making any reaction byproduct that will adversely influence a respiratory treatment. The devices and methods for nitric oxide (NO) generation and nitrogen dioxide (NO.sub.2) removal or scrubbing can be embedded into other therapeutic devices or used alone.

A respiratory pressure therapy system for providing continuous positive air pressure to a patient via a patient interface configured to engage with at least one airway of the patient. The system includes: a flow generator configured to generate supply of breathable gas for delivery to the patient via the patient interface; at least one sensor; a display; and a computing device. The computing device is configured to: receive sensor data that is based on measured physical property of the supply of breathable gas; control, based on the received sensor data, the flow generator to adjust a property of the supply of breathable gas; receive, an input indicating assistance is needed with using the patient interface; receive one or more images of the patient with the patient interface; analyse the received one or more images; and based on the analysis, display instructions for positioning the patient interface.

A nasal prong (230) for sealing with a nasal passage of a patient includes a head portion (235) structured to seal and/or sealingly communicate with the patient's nasal passage and a column or stalk structured to interconnect the head portion with a base. The head portion (235) is configured to direct gas in use away from the septum and/or posteriorly relative to the nasal passage.

A stator assembly has coils in a distributed winding configuration. A poly-phase switched reluctance motor assembly may include a stator assembly with multiple coils in a distributed winding configuration. The stator assembly may have a central bore into which a rotor assembly having multiple poles is received and configured to rotate. A method of controlling a switched reluctance motor may include at least three phases wherein during each conduction period a first phase is energized with negative direction current, a second phase is energized with positive current and there is at least one non-energized phase. During each commutation period either the first phase or second phase switches off to a non-energized state and one of the non-energized phases switches on to an energized state with the same direction current as the first or second phase that was switched off. The switched reluctance motor may include a distributed winding configuration.

A neck strap, a crown strap assembly and a headgear for a breathing mask. The neck strap for a headgear includes a one-piece main body adapted to engage a patient's neck, first and second lower connection portions adapted to connect to first and second lower mask connection straps, and first and second upper connection portions adapted to connect to respective first and second lateral crown straps.

Disclosed is respiratory assistance apparatus comprising a flow generator configured to provide breathing gases to a patient, the breathing gases comprising supplemental oxygen provided from an oxygen source. The respiratory assistance apparatus controller is configured determine a target oxygen concentration of the breathing gases and calculate an estimated future value of the patient's blood oxygen concentration based on a difference between an initial oxygen concentration of the breathing gases and the target oxygen concentration of the breathing gases, and the patients blood oxygen concentration.

A stimulation device may include a tube, where the tube defines a lumen therein and a gas outlet. The gas outlet may be configured to allow gas to pass from the lumen to an exterior of the tube. The stimulation device may also include one or more first electrodes associated with the tube, one or more second electrodes, and a nasal cavity interface proximal of the gas outlet and the one or more first electrodes.

Devices for providing respiratory therapy to a patient are disclosed. One device includes first and second elongated lumens and a nosepiece. The elongated lumens each have a constant internal diameter. The nosepiece portion has a third lumen and a fourth lumen. The third and fourth lumens have constant internal diameters equal to those of the first and second lumens. The third and fourth lumens have inlet ends adapted to be connected to the outlet ends of the first and second lumens without constricting the internal diameter of the first and second lumens. The third and fourth lumens are configured to receive first and second flows of breathing gas from the first and second lumens and deliver the flows of breathing gas to outlets end of the third and fourth lumens. The second flow of breathing gas is maintained separate from the first flow of breathing gas within the nosepiece portion.

A method of estimating a parameter indicative of respiratory flow of a patient being administered flow therapy, comprising: optionally administering a gas at a flow rate to the patient using a flow therapy apparatus with a patient interface, determin—-ing a terminal pressure in, at or proximate the outlet of the patient interface or in, at or proximate the nares of the patient, determin -ing nasal RTF, determining a nasal flow parameter being or indicative of nasal flow based on the pressure and a nasal RTF, and optionally outputting the nasal flow parameter or parameter derived therefrom.
