Abstract
A respiratory assistance apparatus includes a conduit connecting a flow generator and an outlet. The conduit includes a venturi formation. The apparatus further includes an oxygen inlet in fluid communication or selective fluid communication with an oxygen outlet. The oxygen outlet is directed into the conduit and toward a mouth of the venturi formation. The flow generator provides a flow path for air to enter the conduit when the flow generator is not operating.
