A shroud (1020) for a mask system includes a retaining portion structured to retain a frame (1040), a pair of upper headgear connectors (1024) each including an elongated arm (1026) and a slot (1027) at the free end of the arm adapted to receive a headgear strap, and a pair of lower headgear connectors (1025) 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.

A respiratory mask for providing positive pressure therapy having ball jointed elbow, one or more detachable forehead pieces and headgear comprising a spacer fabric region is disclosed herein. The elbow is configured to be removable when oriented to a predetermined position. The forehead pieces are provided in one or more sizes. The spacer fabric region comprises two or more layers wherein the raw edges are turned to the inside of the layers. The seal comprises features that improves seal performance and accommodates a wider variety of facial geometries.

The system includes an air flow generator configured to deliver an air flow at a positive therapeutic pressure during the treatment, and an expiratory valve with an open pressure connected to the air flow generator. The open pressure is dependent on the therapeutic pressure from the air flow generator. The expiratory valve further exerts a back pressure upon each exhalation from the patient sufficient to create a pneumatic splint in the patient's respiratory tract. The exhalation from the patient has a first half followed by a second half, and the back pressure is varied such that during the start of the first half, the back pressure is between 0 and 50% of a peak back pressure, and increases to a peak back pressure in the second half.

A customized sealing member is for a customized mask of a pressure support system. The steps to manufacture the customized sealing member include generating surface geometry data of a face of a patient, the surface geometry data corresponding to and representing a surface geometry of the face of the patient; generating customization data using the surface geometry data, the customization data representing how a seal blank should be modified for the patient; and customizing the seal blank using the customization data such that the customized seal blank is shaped according to the customization data.

Respiratory assembly for use in conjunction with a continuous positive airway pressure (CPAP) equipment is provided. The respiratory assembly includes a conduit coupler comprising a male member and a female member. The respiratory assembly also includes a disposable respiratory mask that defines a central opening therethrough that is sized to receive the male member. A gasket is positioned between the male member and the respiratory mask, the gasket encircling the central opening to provide a sealing thereto. A channel opening of one of the male member and the female member connects to a continuous positive airway pressure (CPAP) mask that couples to one or more of a patient's nare and mouth.

A conduit for delivering a supply of gas under a positive pressure includes a conduit wall having a first conduit end and a second conduit end. The first conduit end is adapted to be attached to the supply of gas. The conduit wall is deformable between (a) an open condition in which the conduit wall defines a conduit passage along which the supply of gas can travel between the first conduit end to the second conduit end, and (b) a collapsed condition in which the conduit wall substantially collapses the conduit passage.

A face mask for delivering oxygen to, and sampling carbon dioxide exhaled from, a subject includes a partition wall that divides the mask into a subject respiratory space that primarily contains carbon dioxide exhaled by the subject, and an oxygen reservoir space that primarily contain oxygen. The partition wall includes one or two holes to which naris conduits are respectively connected. The naris conduit are positioned in proximity to the subject's nares to closely obtain carbon dioxide samples. The naris conduits enable oxygen to flow from the oxygen reservoir space to the subject respiratory space during inhalation, while quickly expelling traces of CO.sub.2, and they configured such that exhaled CO.sub.2 quickly fills them up, during exhalation, and while expelling oxygen traces back to the oxygen reservoir space. During exhalation.

A system including a user information database structured to store first information corresponding to a consumer and a first fit score corresponding to a current product associated with the consumer, a product information database structured to store second information corresponding to a new product, a communication unit structured to communicate with a user device, and a processing unit including a fit score determination module structured to determine a second fit score of the new product based on the first information and the second information, to determine if the second fit score is greater than the first fit score, and to control the communication unit to push a notification to the user device in response to determining that the second fit score is greater than the first fit score.

A coupling arrangement for use in coupling a patient interface to the skin of a patient includes an adhesive arrangement and an application system. The adhesive arrangement includes: a substrate material having a first surface and a second surface opposite the first surface, a first adhesive material provided on the first surface, and a second adhesive material provided on the second surface. The application system is disposed on the first adhesive material and includes a number of separate portions, with each portion formed from a film material. Each separate portion includes: a base disposed on at least a portion of the first adhesive material, and a tab coupled to an interior edge of the base and extending upward and away therefrom, the tab being sized and configured to be grasped by the patient at an end portion opposite the interior edge.
