Abstract
The concentration of exhaled carbon monoxide (CO) may be a useful factor for monitoring the control of airway inflammation in asthma. CO analyzers are not widely used at the present time, but they are portable and not expensive. This CO analyzer may be used in conjunction with home peak flow meters. Thus, exhaled CO measurements may be useful in monitoring the level of control of asthma and response to anti-inflammatory treatments in individual asthmatic patients.
