A method of managing sleep therapy includes inputting characterization data associated with each of a plurality of patients into a database system stored in a memory system and inputting outcome data associated with each of the plurality of patients resulting from use of one of a plurality of interface systems in sleep therapy. The method further includes determining a management option for sleep therapy for a person via execution of the algorithm based at least in part upon an optimization of at least one outcome parameter for the person predicted by at least one model of the algorithm based at least in part upon characterization data of the person input into the database system.

A system for concentrating oxygen inside a mask with filters is provided. The system comprising a mask body having a contoured shape that fits above the patient's nose and mouth; filters which allow gasses but not contaminants to pass through; a port with detachable cap for gas sampling; an inlet port connected which can be open to room air or attached to standard oxygen tubing or a ventilator circuit. The mask may be worn with or without an oxygen source. The mask body is firmly sealed against the patient's face with the filters functioning to prevent microbial contamination of the environment while concentrating oxygen within the lumen of the mask.

A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient's face.

The present specification is directed to a seal forming structure for a patient interface for delivery of air to a patient's airway, wherein the seal forming structure comprises a first section of a thermoformable material and a second section of another material. The present specification is also directed to a patient interface comprising such a seal forming structure, wherein the patient interface further comprises a shell. The specification is also directed to methods for manufacturing such a patient interface.

A method of creating a custom color adhesive securement arrangement for use with a patient interface includes performing a scan of a patient's face, extracting color values of a portion of the patient's face from the scan, determining one or more colors based on the extracted color values, obtaining an adhesive sheet having the one or more colors, and cutting the securement arrangement from the adhesive sheet.

A patient interface comprises a plenum chamber and a seal-forming structure. The seal-forming structure comprises a support structure arranged to support a sealing portion that is adapted to sealing engage the patient's face in use. The seal-forming structure may also include a seal biasing portion configured to inflate under pressurization within the cavity in the cushion assembly in use to extend the reach of the sealing portion and decouple the sealing portion from external forces.

A tracheostoma device holder for holding a tracheostoma device superimposed of a tracheostoma of a person. The tracheostoma device holder may include a plate and a tracheostoma device fitting. The plate may be configured for attachment over a tracheostoma via a proximal side thereof. The plate may include a through hole. The tracheostoma device fitting may include a through passage arranged superimposed the through hole. The tracheostoma device fitting may extend distally from the plate. The plate may further include a disc of a thermoplastic material and a plate material arranged at least laterally of the disc. The plate material may have a melting point different from a melting point of the disc.

A patient interface comprises a support structure and a seal-forming structure. The support structure is arranged to support the sealing portion and is configured to connect to the frame. The sealing portion comprises textile and is attached to the support structure along an outer perimeter of the sealing portion such that in use the sealing portion may be in tension due to reactive stress of the support structure and/or a resilient stretch characteristic of the textile such that the sealing portion exerts a force against the patient's face.

A respiratory assembly is provided. The assembly includes at least one post having a nasal engaging portion on about a first end thereof for delivering treatment gases to the nasal cavity of a patient. A pair of tubes capable of receiving gas from a hose or fluid source are selectively engaged with the pair of posts for delivering treatment gases from the inlet through the receptacle and into the nasal cavity of the patient. A splitter may be positioned between the hose or fluid source and the pair of tubes. Ball and socket joints may provide enhanced flexibility of the assembly while in use.

A shroud for a mask system includes a retaining portion structured to retain a frame, a pair of upper headgear connectors each including an elongated arm and a slot at the free end of the arm adapted to receive a headgear strap, and a pair of lower headgear connectors each adapted to attach to a headgear strap. The retaining portion, the upper headgear connectors, and the lower headgear connectors are integrally formed as a one piece structure.
