During the administration of NO to a patient, NO reacts with oxygen in the respiratory gas to form NO.sub.2. Since NO.sub.2 is a toxic gas, minimizing the formation of this gas is important. A previously unknown property of NO is that an initial amount of NO.sub.2 is formed when NO and O.sub.2 mix.

During the administration of NO to a patient, NO reacts with oxygen in the respiratory gas to form NO.sub.2. Since NO.sub.2 is a toxic gas, minimizing the formation of this gas is important. A previously unknown property of NO is that an initial amount of NO.sub.2 is formed when NO and O.sub.2 mix. By adding NO to respiratory gas at a number of spaced-apart mixing points, the total initial amount of NO.sub.2 formed can be reduced. In a method and a device for mixing and administering NO, the gas containing NO is supplied to a flow divider for distributing the flow and sending sub-flows to a number of various mixing points.
