Abstract:
Exhaled gaseous signal molecules such as nitric oxide(NO),carbon monoxide(CO) and hydrogen sulfide(H2S) can be measured with a non-invasive technique.The fraction of NO level in exhaled gaseous of patients with airway inflammatory illness(such as bronchial asthma) significantly increases.No in exhaled gaseous is one of the markers in the diagnosis of asthma,and it is also a marker of anti-inflammatory response for patients with asthma.The fraction of CO level in exhaled gaseous of patients with bronchial asthma is also si-gnificantly elevated.Both NO and CO in exhaled gaseous in other airway inflammatory illness,such as chronic obstructive pulmonary disease,chronic bronchitis and cystic fibrosis are also evidently changed.Measuring exhaled gaseous signal molecules can provide important basis for the diagnosis and treatment of airway inflammatory illness.
