A method for analyzing therapeutic gas is disclosed. The method includes a therapeutic gas being added as a supplement to a mixture gas, and the mixture gas supplemented with the therapeutic gas being delivered through a conduit. The method further includes receiving a sample gas, comprising a sample of the mixture gas supplemented with the therapeutic gas, from the conduit through a gas sample line. The method additionally includes raising or lowering the humidity of the sample gas, by passing the sample gas through a water-permeable tubular membrane, wherein the sample gas leaving the water-permeable tubular membrane is a humidity conditioned sample gas. The method also includes analyzing the humidity conditioned sample gas to determine a mixing ratio and concurrent with passing the sample gas through the water-permeable tubular membrane, maintaining a section of the water permeable tubular as a ventilated water permeable tubular membrane, by operations that include exposing outer surfaces of the ventilated water permeable tubular membrane to an ambient air flow. The therapeutic gas includes nitric oxide.
