Abstract
A respiratory nitric oxide meter includes a respiratory connector designed to be supported in contact with a subject and to pass respiratory gases as the subject breathes. A flow pathway receives and passes the respiration gases. One end of the pathway is in fluid communication with the respiratory connector, and the other end is in fluid communication with a reservoir of respiratory gases. A nitric oxide concentration sensor generates electrical signals as a function of the instantaneous fraction of nitric oxide as the respiration gases pass through the flow pathway.
