Nitric oxide is a gas detectable in exhaled breath of humans and is recognized as a useful biomarker for asthma diagnosis and mon- itoring. Several studies have shown evidence of higher levels of exhaled nitric oxide in patients with respiratory diseases as com- pared with the healthy population. The possibility of using exhaled nitric oxide measurement as a tool for diagnosing and monitoring occupational exposures to allergic or toxic irritants is reviewed and discussed.
