Exhaled nitric oxide in asthma: from bench to bedside.

Author information

Department of Medicine, National Jewish Medical and Research Center, 1400 Jackson Street, Denver, CO 80206, USA.


With more than 600 publications, exhaled nitric oxide (NO) has been extensively investigated as a noninvasive marker of airway inflammation in a research setting. This clinical rostrum presents a synopsis of the latest research about this novel marker in asthma and suggests how it might move from bench to bedside. Specifically, we review the evidence citing the applicability of exhaled NO in diagnosing asthma, monitoring the response to therapy, evaluating current symptom control, and predicting exacerbations of asthma. These studies support a role for exhaled NO in the evaluation and treatment of asthma in the clinical arena.
