Abstract: An embodiment provides a system having a non-invasive ventilation patient interface. In one example, the system includes a headgear element and a non-invasive ventilation patient interface detachably coupled to the headgear element. The non-invasive ventilation patient interface includes a conduit having an entrainment opening and a nasal opening disposed along a conduit axis. A pressure sensing element is provided proximate to the nasal opening. One or more orifices proximate to the entrainment opening are configured to expel a jet of gas. One or more surfaces have a first end and a second end, with the first end being proximate to the one or more orifices and directing a flow of the jet of gas expelled from the one or more orifices, the second end being closer to the nasal opening than the first end. In an operational state, the jet of gas adheres to the one or more surfaces via the Coanda effect, thereby entraining ambient air into the entrainment opening to deliver the jet of gas and the ambient air through the nasal opening of the conduit.

Abstract: Provided is a system for adsorbing a gaseous component comprising nitrogen from a pressurized flow of air containing the gaseous component. The system comprises a first adsorption bed, and a second adsorption bed. Each of the adsorption beds are suitable for selectively adsorbing the gaseous component from the flow of air to produce a product gas having a higher oxygen concentration than that of the air. The system includes an adjustable feed gas supply which alternately supplies the first adsorption bed and the second adsorption bed with the air. The first adsorption bed is supplied with air during a first half cycle of operation of the system, and the second adsorption bed is then supplied with air during a second half cycle of operation of the system. The feed gas supply enables adjustment of at least one parameter relating to the amount or respective amounts of air being supplied to the first adsorption bed in the first half cycle and/or to the second adsorption bed in the second half cycle. A connection and valve assembly is provided between the first and second adsorption beds. The connection and valve assembly diverts a portion of the product gas, produced from the respective absorption bed being supplied with the flow of air during the respective half cycle, to the other adsorption bed. This causes previously adsorbed gaseous component to be released from latter. The released gaseous component then escapes from the system, e.g. to the atmosphere, via a vent. A sensor system determines a measure of the flow rate of waste gas, including the released gaseous component, escaping from the system via the vent. The at least one parameter can be adjusted based on the measure in order to tune the performance of the system. Further provided is a method for operating the system.

Abstract: A ventilation device for providing a gas mixture for a user including a compressor to output compressed air; a valve to receive the compressed air and medical gas and selectively output a gas flow of at least one of the medical gas and the compressed air; a patient interface configured to provide the output gas flow of the valve; and a controller to control the valve to deliver substantially only the medical gas to the patient interface during a first portion of the inspiratory period and deliver substantially only the compressed air to the patient interface during a second portion of the inspiratory period.
