  • Publication number: 20200094004
    Abstract: Systems, methods, and/or apparatuses for acclimatizing a user to positive airway pressure (PAP) therapy are provided. Generally, a sub-therapeutic treatment pressure is provided initially. It may be ramped up to a full treatment pressure over the course of one or more therapy sessions. The pressure level may be ramped up based on, for example, sleep state, sleep phase, patient compliance with types of treatment (e.g. bilevel vs. CPAP, etc.), clinician input (either at the site, remotely, via pre-programmed smartcards, etc.), etc. Such techniques may be used alone or in combination.

  • Patent number: 10576226
    Abstract: An air delivery system includes a controllable flow generator, a primary controller, and an auxiliary controller. The flow generator is operable to generate a supply of pressurized breathable gas to be provided to a patient for treatment. The primary controller is associated with at least one primary control feature to select at least a first aspect of operation of the flow generator. The auxiliary controller is associated with at least one auxiliary control feature to select at least a second aspect of operation of the flow generator. The second aspect selected by the auxiliary controller is different than the first aspect selected by the primary controller. The primary and auxiliary controllers may be interchangeably usable to control operation of the flow generator.

  • Patent number: 10569041
    Abstract: A mask system for use between a patient and device to deliver a breathable gas to the patient includes a mouth cushion, a pair of nasal prongs, an elbow, and a headgear assembly. The mouth cushion is structured to sealingly engage around an exterior of a patient's mouth in use, and the pair of nasal prongs are structured to sealingly communicate with nasal passages of a patient's nose in use. The elbow delivers breathable gas to the patient. The headgear assembly maintains the mouth cushion and the nasal prongs in a desired position on the patient's face. The headgear assembly provides a substantially round crown strap that cups the parietal bone and occipital bone of the patient's head in use.

  • Publication number: 20190269870
    Abstract: An air delivery system for providing a supply of air from a source of air at positive pressure to an interfacing structure located at the entrance to the airways of a patient includes a manifold adapted to connect with the supply of positive air pressure and at least one tube connected to the manifold and adapted to deliver the supply of air to the interfacing structure. Each tube is structured to allow movement between an open phase in which the tube allows the passage of air and a collapsed phase in which the tube is collapsed. Each tube is structured such that weight of a typical patient's head against bedding apparel is sufficient to collapse the tube from the open phase to the collapsed phase.
