A device and method of generating an enriched gas within a nasal vestibule of a patient includes a housing, a chamber, a chamber inlet, a pump, a molecular sieve bed, a release outlet, and a breath duct. The chamber is configured to be received within the nasal vestibule. The pump is configured to direct an ambient air from an ambient environment into the chamber. The molecular sieve bed is positioned within the chamber and configured to collect a predetermined molecule from the ambient air thereby generating the enriched gas. The release outlet is configured to discharge the enriched gas from the chamber into the nasal vestibule. The breath duct longitudinally extends through the housing such that the breath duct is configured to fluidly communicate a fluid flow through the housing for nasal breathing by the patient while the chamber is positioned within the nasal vestibule.

Disclosed is a respiratory interface device (1) and components thereof. The respiratory interface device (1) comprises a body (2), a frame (3), and an inlet conduit (4). The frame has a front wall (10a), side walls (10b), and side arms (12), and a support platform (11) extending rearwardly from the front wall (10a). An inlet opening (13) is defined in the support platform (11). The body (2) forms a chamber with the support platform (11) and comprises at least one nasal outlet (5), a base opening (7), and at least one further opening (6), through which the support platform (11) extends. The inlet conduit (4) comprises a connector (18) that clamps the body (2) and the support platform (11) together.

A method includes receiving data associated with a sleep session of a user. The method also includes determining that the user is experiencing or has experienced an event based at least in part on the data. The method also includes causing pressurized air to be directed from a respiratory device to a multi-compartment bladder in response to determining that the user is experiencing or has experienced the event to aid in modifying a position of a head of the user.

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.

Devices, systems, and methods for monitoring respiration using surface temperature, humidity, air pressure, carbon dioxide gas sensors, pulse oximetry sensors and electromyography sensors, and/or acceleration sensors to obtain information related to respiration rate (RR), exhalation/inhalation strength, exhalation/inhalation volume, exhalation/inhalation acceleration, and/or exhalation/inhalation regularity.

A nasal interface uses asymmetrical nasal delivery elements to deliver an asymmetrical flow through the interface to both nares or to either nare, and a mouthpiece may be inserted to maintain a leak, to improve dead space clearance in the upper airways, decrease peak expiratory pressure, reduce noise, increase safety of the therapy for smaller patients and reduce resistance in the interface allowing desired flow rates to be achieved at reduced motor speeds of associated flow generating devices. Different forms of fittings, such as sleeves or inserts can be attached to nasal delivery elements to improve or optimise the therapeutic effects of nasal high flow. It may allow high pressures to be achieved at lower flow rates, reduce noise, improve patient comfort and efficiently clear anatomical dead space.

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.

The present invention provides new devices, systems, and methods for delivering enriched oxygen to recipients (e.g., chronically ill patients, such as COPD patients). One aspect is a more efficient portable oxygen concentrator that is configured to deliver an enriched oxygen airflow having a significantly lower overall oxygen concentration and greater overall volume administered as compared to currently marketed or known portable oxygen concentrators. Administering the lower oxygen concentration at higher volumes allows for the present portable oxygen concentrators to deliver an equivalent number of moles of oxygen as administered by traditional portable concentrators while increasing the efficiency of the system and the ability of the system to maintain the therapeutic level of oxygen concentration for a longer period.

An oxygen delivery apparatus wearable by user includes a frame including nose pads connected to a bridge portion, an oxygen inlet defined by one of the nose pads, an oxygen inlet defined by the frame, and a hollow channel contained by the frame. The oxygen inlet and oxygen outlet are in fluid communication via the hollow channel. The frame can be formed as a monolithic structure using additive manufacturing. A nasal prong can be connected to the oxygen outlet such that a prong outlet of the prong is in fluid communication with the hollow channel. The prong outlet is positioned within a nostril of the user during use of the apparatus. A method of fabricating the frame includes obtaining measurement information for at least one of a head feature or facial characteristic of the user and generating a digital model of the oxygen delivery apparatus using the measurement information.

An oxygen facemask that has pathogen filtering capability can be used in conjunction with a capnometer to measure carbon dioxide levels in a patient. Facemask can be used to provide critical breathing assistance to patients. In certain instances, a patient’s blood CO2 level can be the difference between a good versus a bad outcome. Accordingly, in certain circumstances there is great value in evaluating a patient’s CO2 with a capnometer from breath exiting the facemask, which correlates to CO2 in their blood. Because some of these patients carry airborne transmissible viruses, an exhalent filtration system is envisioned included in the facemask that filters the patient’s breath from those helping the patient in a common space. The exhalent filtration system incorporates both filtering air exiting the facemask directly into a common space and indirectly into the common space by way of the capnometer.
