Abstract: Devices and methods for providing respiratory therapy are disclosed. One device includes a first lumen, a second lumen, and a bridge with at least one opening. The first lumen has a first inlet end to receive a first flow of breathing gas, a first outlet end to deliver the first flow, and a first bend between the first inlet end and the first outlet end. The second lumen has a second inlet end to receive a second flow of breathing gas, a second outlet end to deliver the second flow, and a second bend between the second inlet end and the second outlet end. The bridge separates the first lumen and the second lumen, attaches to the first lumen at the first bend and the second lumen at the second bend, and is configured to maintain the first flow of breathing gas separate from the second flow of breathing gas.

Abstract: Systems and methods for providing respiratory therapy are disclosed. One device includes a nasal cannula comprising at least at one nasal prong, tubing and a breathing gas conduit. The nasal prong has a proximal tip and a distal end connected to the breathing gas conduit. The breathing gas conduit has an inlet port, an outlet port, and a walled flow path connecting the inlet and outlet ports, such that the conduit directs the breathing gas from the tubing to the proximal tip of the nasal prong. A nebulizer is secured to the nasal cannula and operable to aerosolize a medicament via a vibrating mesh. The vibrating mesh is secured to the nasal cannula and is positioned adjacent to the breathing gas conduit such that the aerosol is entrained with the breathing gas at proximal tip of the nasal prong.

Abstract: Systems, methods, and devices for humidifying a breathing gas using a vapor transfer unit are presented. The method includes providing a first vapor transfer unit having a gas passage and a liquid passage, delivering a liquid to the liquid passage, delivering a gas to the gas passage, humidifying the gas by delivering vapor from the liquid in the liquid passage to the gas in the gas passage, exiting the humidified gas outside the vapor transfer unit at first relative humidity and at a high gas flow rate, and reducing the gas flow rate through the first vapor transfer unit to less than a low gas flow rate, while preventing the relative humidity from exceeding the first relative humidity by more than an acceptable margin.

Abstract: An adaptive gas mixture controller system. A pulse oximeter interface receives pulse oximeter data. A gas blender interface communicates with a separate externally connected gas blender. A processor receives pulse oximeter data via the pulse oximeter interface and outputs data to the gas blender interface for adaptive feedback control of the gas mixture based upon the SpO2 level signals from the pulse oximeter interface. When the processor receives data from the gas blender indicating that the gas mixture has been manually changed, enters a manual override mode and halts sending adaptive feedback control signals to the gas blender. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Abstract: Systems and methods for providing respiratory therapy are disclosed. The system includes a nebulizer operable to aerosolize a medicament, a cylindrical mixing chamber, an impacting cap and a recirculation tube. The mixing chamber has an inlet port, an outlet port, an aerosol port in fluid communication with the nebulizer, and a drainage port. The inlet port receives a flow of breathing gas. The mixing chamber receives the aerosol via the aerosol port, entrains aerosol into the flow of breathing gas, and delivers the breathing gas entrained with aerosol to the outlet port. The impacting cap receives and coalesces a portion of the aerosol into droplets within the space defined by the mixing chamber and the impacting cap. The mixing chamber is also configured to direct rain-out resulting from the droplets to the drainage port. The system also includes a recirculation tube to return the rain-out to the nebulizer.

Abstract: Systems, devices, and methods for coupling a tracheostomy tube to a source of humidified breathing gas are disclosed. An adaptor includes a housing, a tracheostomy tube connection device, and a baffle. The housing has an interior surface, an exterior surface, and a breathing gas port. The tracheostomy tube connection device is positioned within the housing and includes an input port for receiving a flow of humidified breathing gas from the breathing gas port and an output port for coupling with the tracheostomy tube. The tracheostomy tube connection device has an internal surface defining a breathing gas passage and an external surface spaced from the interior surface of the housing to create a condensation passage. The baffle may be positioned between the breathing gas port and the input port to cause controlled condensation from the flow of humidified breathing gas by disrupting the flow of humidified breathing gas.

Abstract: 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.

Abstract: Apparatus and methods for delivering humidified breathing gas to a patient are provided. The apparatus includes a humidification system configured to deliver humidified breathing gas to a patient. The humidification system includes a vapor transfer unit and a base unit. The vapor transfer unit includes a liquid passage, a breathing gas passage, and a vapor transfer device positioned to transfer vapor to the breathing gas passage from the liquid passage. The base unit includes a base unit that releasably engages the vapor transfer unit to enable reuse of the base unit and selective disposal of the vapor transfer unit. The liquid passage is not coupled to the base unit for liquid flow therebetween when the vapor transfer unit is received by the base unit.
