A nasal continuous positive airway pressure device for lowering patient breathing effort comprising: an inspiratory tubing in fluid communication with at least two nasal prongs； expiratory tubing； and a generator body coupled therebetween, the generator body comprising: at least two jets for receiving gas from the inspiratory tubing； and a flow enhancer for directing received gas, the flow enhancer comprising: a gas manager configured for channeling received gas towards a jet impingement point via at least two jet paths； a fluidic flip trigger configured for triggering a fluidic flip of channeled gas back towards the expiratory tubing by directing a first portion of exhaled patient breath towards the jet impingement point along a first pathway； and an isolated pathway manager for directing a second portion of the exhaled patient breath along a second pathway towards the expiratory tubing, the second pathway isolated from the first pathway.
