Abstract: The present invention is directed to a nitric gas dispenser for mammals on the run. The dispenser has a housing that contains a valve mechanism. The valve mechanism is interconnected between a nitric gas dispersal component that provides nitric gas at a desired pressure and a gas delivery system that provides the nitric gas at the desired pressure to the mammal. The valve mechanism controls the flow of the nitric gas between the nitric gas dispersal component and the gas delivery system. The dispenser also has a pressure sensor that is positioned along the gas delivery system and determines when the mammal is taking a breadth. If the pressure sensor determines the mammal is taking a breadth, the pressure sensor transmits a breadth signal to a microprocessor. The microprocessor then determines if the mammal is within a prescribed time frame for the mammal to be administered nitric gas.

Abstract: A system controls and manages administration of a therapeutic gas, such as NO, O2, or the like, to a spontaneously breathing, non-ventilated patient such that concentrated NO is as low as reasonably possible while delivering the desired amount of NO to the distal portions of the lungs. The system includes an entrainment cell that provides remote, turbulent mixing with low temporal latency and can be used with a nasal cannula or a mask. The entrainment cell uses room air to dilute the therapeutic gas; however, supplementary gases can also be used. A baffle can be included to promote mixing and a flow sensor can also be used if desired. Multiple ports can be included in the entrainment cell. An equalizing valve is also disclosed.
