A nebulizer (10) for providing a select oxygen concentration and total flow of respiratory gas includes at least two oxygen nozzles (102, 104, 106, 108), each oxygen nozzle having an outlet. A pressurized oxygen supply is connected in fluid communication to each nozzle. A liquid outlet (80) corresponding to each nozzle (102, 104, 106, 108) is positioned proximate the nozzle outlet of the corresponding nozzle for nebulization of liquid from the liquid outlet (80) in a stream of oxygen flowing from the gas outlet of each nozzle (102, 104, 106, 108). A liquid supply (174) is connected in liquid communication to each liquid outlet (80). An oxygen adjustment mechanism is provided in fluid communication with at least one of the oxygen nozzles (102, 104, 106, 108) for selectively recruiting the at least one oxygen nozzle and preventing gas from flowing from the at least one oxygen nozzle. |
