<p>A respiratory nitric oxide meter (10) includes a respiratory connector (14) designed to be supported in contact with a subject and to pass respiratory gases as the subject breathes. A flow pathway (20) receives and passes the respiration gases. One end of the pathway (20) is in fluid communication with the respiratory connector (14), and the other end is in fluid communication with a reservoir of respiratory gases. A nitric oxide concentration sensor (24) generates electrical signals as a function of the instantaneous fraction of nitric oxide as the respiration gases pass through the flow pathway (20).</p> |
