In conjunction with the diagnosis of conditions in and treatment of the lungs, a small amount of NO is supplied to the lungs in some cases. A gas mixture for this purpose is disclosed in which an inert, non-toxic trace gas is present in an exact concentration in relation to NO, in order to simply and safely control the amount of NO then supplied to the lungs. The amount of NO supplied can be determined by determining the concentration of the trace gas. A method and device for administering breathing gas to a patient together with the aforementioned gas mixture are also disclosed.
