Experimental lung research
-
Smoking is known to have a long-term impact on lung function; however, the acute physiological response of smoking a single cigarette and the influential role of pack years and cigarettes per day on pulmonary indices remains an area of interest, especially among young smokers. ⋯ The present study indicates that the consumption of a single cigarette may alter lung mechanics and FENO production among young smokers. Further research is needed to assess the mechanisms and washout period after which these parameters return to normal.
