ATS 2007, SAN FRANCISCO—An “electronic nose” may one day be used to diagnose asthma, say researchers who are presenting a preliminary study of the device at the American Thoracic Society 2007 International Conference, on Monday, May 21. The device contains chemical vapor sensors that react to the presence of volatile organic compounds, or VOCs, in a person’s exhaled breath. “A person’s breath contains a mixture of thousands of VOCs that may be used as markers of lung disease,” says researcher Silvano Dragonieri, M.D., of Leiden University Medical Center in the Netherlands.>>> Discuss This Story
