The system may include a scan mechanism that causes the optical element to scan the cornea at a plurality of depths, and the controller may determine a measurement of the fluorescing agent in the cornea as a function of depth.

Abstract: Asthma creates inflation of the epithelial cells in the airway of a patient. Inflammation causes epithelial cells to increase the production of nitric oxide far above the normally low levels. Therefore, clinicians can detect biomarkers of Asthma and other maladies by measuring the concentration of exhaled nitric oxide (“eNO”) for fractional exhaled nitric oxide (“FeNO”).

Accordingly, disclosed are systems and methods to determine the amount of nitric oxide exhaled that compensate for a variable flow rate of exhaling, and do not assume a constant flow rate.
