ABSTRACT
There has recently been an explosion of interest in the analysis of breath constituents as a way of monitoring inflammation and oxidative stress in the lungs. Although most studies have focused on exhaled nitric oxide (NO), recently several other volatile gases (carbon monoxide, ethane, pentane) have also been used. In addition, several endogenous substances (inflammatory mediators, cytokines, oxidants) may be detected in expired breath condensates, opening up new perspectives for exhaled breath analysis.
