Abstract:
Cough is a frequent chief complaint of outpatients, and is caused by various diseases. Fractional exhaled nitric oxide (FeNO) measurement is employed to evaluate airway eosinophilic inflammation. We investigated the usefulness of FeNO measurement for the differentiation of diseases in 202 patients who consulted our department. The numbers of consultations required to determine the therapeutic strategy were compared between before and after the introduction of FeNO measurement. The numbers of consultations before treatment were 2.00 +/- 1.31 (n = 140) and 1.60 +/- 0.65 (n = 62) before and after FeNO measurement, respectively (p = 0.046). In patients with cough variant asthma or bronchial asthma, the numbers were 2.15 +/- 1.60 and 1.40 +/- 0.67 before and after FeNO measurement, respectively (p = 0.003). FeNO measurement may be useful for cough treatment.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
