A nasal continuous positive airway pressure device for lowering patient breathing effort comprising: an inspiratory tubing (102) in fluid communication with at least two nasal prongs (104); expiratory tubing (106); and a generator body (108) coupled therebetween, the generator body comprising: at least two jets (110a, 110b) for receiving gas from the inspiratory tubing; and a flow enhancer (112) for directing received gas, the flow enhancer comprising: a gas manager configured for channelling received gas towards a jet impingement point (116) via at least two jet paths (118a, 118b); a fluidic flip trigger configured for triggering a fluidic flip of channelled gas back towards the expiratory tubing by directing a first portion of exhaled patient breath towards the jet impingement point along a first pathway (122); and an isolated pathway manager for directing a second portion of the exhaled patient breath along a second pathway (126) towards the expiratory tubing, the second pathway isolated from the first pathway.
