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.
